How to disassemble and clean any laptop yourself. Step by step guide. How to disassemble a laptop? Instructions for disassembling a laptop yourself How to open an asus eee pc flare series

During the operation of a laptop, sooner or later the need for service arises. More often this is due to excessive overheating of the device, as a result of which slow operation is observed. Overheating occurs when the cooling system malfunctions. A large amount of dust accumulates in the fan and makes it difficult for it to function effectively.

Disassembling a laptop

Service maintenance involves cleaning the cooling system and replacing thermal paste on the chips. These procedures usually require complete disassembly of the device.

Another reason to disassemble a laptop may be the need for an upgrade. Modern technologies are developing at a pace that even owners of advanced cars cannot always keep up with. In this case, manufacturers offer users to increase the capabilities of the device by adding or replacing components. Some devices provide convenient access to the components necessary for this, which allows you to avoid disassembling the entire device. For other devices this will be a necessity.

In addition to these reasons, disassembly may be required for repairs. If any component fails, it must be replaced. And without disassembling there is no way to get to such a component.

Important! Manufacturers assemble devices in their own way. It is difficult to create any universal disassembly scheme. But the main steps are approximately the same for each model.

Preparation

Before you start disassembling your laptop, you need to prepare necessary tools. For convenience, it is recommended to take:

Screwdriver Set;
several cups for screws;
sheets of paper for notes and diagrams;
thermal paste for chips;

This list is typical for standard laptop servicing. It can be supplemented with anything else, depending on the purpose of disassembly.

How to disassemble a laptop

Disassembly can be considered using devices from HP as an example. The devices of this company have a fairly typical design. During disassembly, a certain procedure must be followed. If this order is neglected, the results can be very disastrous. Let us describe the main stages of disassembling the device.

Disconnect the battery

Battery disconnection

The first step is to always disconnect the battery from the case. Usually, the battery can be disconnected quite simply by removing the latches. However, in some models the battery is located internally, making it difficult to quickly access. Disassembly of such devices must be done with the greatest care and attention.

Disconnecting the battery is necessary in order to de-energize the device components. After all, if you disassemble the device under voltage, there is a high probability of shorting any contacts and thereby causing short circuit. This will inevitably lead to failure of some components. And such “service” turns into very serious and expensive repairs.

Unscrew all visible bolts on the bottom

Unscrewing the bolts

Direct disassembly should begin by unscrewing the visible bolts on the bottom. They can hold the laptop lid together, hold the motherboard or any component. The bolts can be of different lengths, so you need to remember their location. To do this, you can use a sketched diagram.

It is worth noting that different screwdrivers may be required to remove the bolts. Most often, it is a cross and in the form of an “asterisk”.

If the bolt does not come off, you may need to select a different tool. If you apply too much force when unscrewing, you can damage the bolt head. The notches may become misaligned and further use of the bolt will be difficult.

Remove all the caps on the bottom and unscrew all the bolts underneath them

Removing covers

Many devices have special covers on the bottom of the case that provide access to some components of the device. These covers are bolted on. They also need to be removed. Under the covers there will be components and their fastenings. The bolts under the covers also need to be unscrewed.

Disable Wi-Fi module, hard drive, RAM, DVD

Disabling components

Next, you need to remove the components to which you have access. Usually the first step is to remove the Wi-Fi module. It is mounted on special guides and connected to two antennas. The antennas must be carefully disconnected by pulling the wires. Sometimes you may need to pry the plugs with something.

If access to the hard drive is opened, it must be removed. The disk is secured with bolts, after unscrewing which you need to carefully pull the component. If there are no obstructions, the disc should come out easily.

Covers on the bottom usually hide access to the RAM for easy replacement. To disassemble a laptop, it is not necessary to remove the RAM, but it can be done for convenience. The RAM strips are secured using special latches. Having bent these latches, you need to smoothly pull the bar and pull it out.

At this point in disassembly you can usually pull it out disk drive. It is attached to special bolts or latches. Once the fasteners are loosened, the drive is pulled out from the side.

In further disassembly of the device, differences begin depending on the manufacturer. You need to turn the device over and look at the keyboard. It can be removable or non-removable. A detachable keyboard is usually fairly easy to identify. It is a kind of module, clearly separated from the very top cover of the laptop.

If the keyboard is removable, remove it

Removing the Keyboard

If it is discovered that the keyboard can be removed, then this is where further disassembly continues. Most manufacturers secure this keyboard with latches. In this case, a pick or some flat object that can be used to pry the keyboard can be very useful. Using this “spatula” you need to go around the entire perimeter of the keyboard and unclip the fasteners. This must be done as carefully as possible, since the fasteners are plastic and quite fragile. Excessive force can easily damage or even break them. The consequence will be a permanent gap between the case and the keyboard. Once the fasteners are released, the keyboard should come off.

Some keyboards are equipped with additional frames on top. In this case, before removing the block itself, you need to remove this frame.

Everything is quite simple, but it turns out that many manufacturers additionally glue the keyboards. In this case, it will take a little more time and patience to disconnect the component.

The keyboard is attached to motherboard using a special cable that must be disconnected. This procedure is carried out with the utmost care so as not to damage the wiring.

We unscrew all visible bolts under the keyboard, remove all cables and connectors

Disconnecting cables

Once the keyboard is removed, you need to inspect the surface underneath it. There should be a large number of bolts holding the parts together. The bolts need to be unscrewed. Just like in the beginning, the location of the bolts needs to be remembered. Next, the cables going from the components to the motherboard are disconnected. Removing cables can be quite a labor-intensive process. All cables are disconnected differently. Some need to be pulled sideways, others up. Don't forget about the snap fasteners that need to be bent.

Carefully open the laptop from the side around the perimeter and remove the top cover

Removing the Top Cover

Next comes, perhaps, the most labor-intensive process, which will require remarkable patience from the examiner. It is necessary to detach the top cover and open access to the motherboard. To do this, using a mediator, you need to walk around the entire perimeter of the device and unclip the fasteners. Under no circumstances should you rush. If the lid does not come off after the first time, then you need to repeat the procedure again. This continues until the top cover comes off with a little force.

Unscrew the remaining screws and disconnect the connectors, remove the motherboard

Motherboard

After removing the top cover, the exposed surface is inspected. If there are any screws, they must be removed. The same goes for the back of the laptop. Once the screws are removed, you can begin to disconnect the connectors. Once this procedure is completed, the motherboard can be removed and properly serviced.

Reassembling in reverse order

Once the maintenance is completed, it becomes necessary to assemble the device. The device is assembled in the reverse order in exactly the same way. The screws are screwed into place. Cables, connectors and sockets are connected. Inserted HDD, drive and RAM. If no latches were broken during disassembly, the laptop should reassemble without any problems. There should be no gaps.

Service maintenance

Since the most common reason for disassembling a laptop is its service, it is necessary to understand how it is carried out.

First of all, the disassembled device contains the cooling system. It is necessary to unscrew all the screws holding it above the processor and near the cooler. The screws near the processor are usually labeled with numbers. They need to be unscrewed in accordance with this number. This is designed to prevent uneven load on the processor, which could damage its contacts.

After the screws are unscrewed, you need to remove the cooling system. Next, the cooler itself is removed. If a lot of dust has accumulated in it, it must be removed. This is done using a special brush. If necessary, the cooler is lubricated.

Next is replacing the thermal paste on the processor. The old paste must be removed using a cotton swab soaked in alcohol. The new paste is applied in a very small amount and distributed in an even layer over the surface of the chip. The cooling system is reassembled in reverse order and the service is completed.

Differences in the disassembly process between different manufacturers

Various manufacturers

Laptops from HP, Asus, Acer and Lenovo are disassembled almost identically. The entire procedure remains the same for all models. But some differences are still present. They consist, first of all, in the location of the screws, the type of fastenings and the design of the keyboard. There may also be differences in the location of the device components themselves, such as the cooling system, processor, video card, etc.

As for the materials from which the devices are made, it is usually plastic. It is light, strong and durable. However, HP prefers to produce models with an aluminum body. It is much stronger than plastic, and also heavier.

Tips for subtleties when disassembling a laptop yourself

Tips for disassembly

Disassembling a laptop yourself is a rather complicated process, especially if you have no experience in this matter. There are several basic tips, following which, even the most inexperienced user will understand how to quickly and correctly disassemble a laptop.

It is very important to remember which bolts were in which places. Otherwise, there is a possibility of damaging not only the mounting points themselves, but also ending up with a completely loose device. Such a device will definitely not last long.

One of the most important advice is that you should not apply too much force when disassembling. It’s better to double-check again to see if there is any screw left. Some screws may be hidden behind stickers or special support structures. There's no need to rush. Excessive zeal in applying force will lead to very significant damage. Moreover, such breakdowns not only have aesthetic disadvantages, but can even affect the operation of the device.

Even if the purpose of disassembly is not to clean the cooling fan and replace thermal paste, such procedures will definitely not be superfluous. Thermal paste must be applied to the chips in a very thin layer, which will smooth out possible surface irregularities.

If any problems arise during disassembly that cannot be resolved, it is better to contact service center. And in general, if there is no desire to thoroughly study the structure of the device, it is more advisable to leave the disassembly to qualified specialists.

All basic disassembly articles describe the process associated with the main part of the device, which contains the motherboard and all components. But sometimes it may be necessary to disassemble the upper part. There is a matrix and some other components, depending on the configuration of the device. This part is also not difficult to disassemble. You just need to unscrew all the screws, unclip the fasteners and disconnect the cable. All this may be required if the laptop screen itself has failed. The screws in this part are usually hidden with special plugs.

Important! Any independent disassembly of the device is a risk. In this regard, manufacturers regulate this issue very clearly. If the device is subjected to unauthorized disassembly during the warranty period, the warranty is immediately void. This fact must be taken into account, especially for owners of very expensive devices.

Video

There are many videos on the Internet about step-by-step disassembly popular models laptops. Before you begin this procedure, it is best to familiarize yourself with such materials. Now you can find videos for almost any model. Such videos show the disassembly process in as much detail as possible, with necessary and useful comments from those who have already successfully carried out such a procedure.

So, here we have the Asus EEE PC 900 netbook:

Specification

Dimensions L x W x H	225 x 170 x 21.5/35 mm
Weight	0.99kg

It is quite small and very convenient. And in general, this is one of the most popular netbooks of all times.
It has an older brother EEE PC 901. The difference is not big - one number in the title, a slightly more powerful processor and the presence of a Bluetooth module. If it is difficult to do something with the processor, then with BT it is quite possible to help. In theory, after all these alterations, the happy owner will have the opportunity to listen to his favorite music on Bluetooth headphones without any problems.

But, to the point! Let's start to sort it out.

First you need to unscrew all the bolts marked in the picture above. You can immediately remove the SSD module by unscrewing the 2 bolts that hold it in place.

You don't have to worry about sorting the bolts - there are only 2 varieties.
The short ones attach wi-fi and ssd, and all the rest (16 pieces) are the same.

After that, lift the keyboard and disconnect the cable.

Under the keyboard there will be several more bolts (5, I think) that secure the aluminum plate.
At this step you will have to overcome the fear of removing the device from warranty :)

I have already reached the point of professionalism:

In addition to the bolts, the plate will also be held in place by the latches that are located on the sides of the cover and the touchpad cable, which is detached in the same way as the Asus EEE PC keyboard cable.

Well, here we have the payment. Note the blue spots on the chip and the back of the cover. This is a thermal pad through which the processor and bridges are cooled. The lid itself serves as a radiator (it’s aluminum for a reason).
In order to conveniently solder the eeepc board, it must be completely removed from the netbook case. But before that, you need to disconnect all the cables that go to it. This is a vga cable for microphone, speakers and camera. Finding them is not difficult - there are no other wires there yet except these. That is, you need to disconnect everything :)

Here is the VGA connected to the board

But it’s no longer in the connector:

After everything has been disconnected, you need to disconnect the board. The latches that hold it in place are located in the touchpad area.

In order to remove the board from them, just pry it off with a screwdriver. They are very difficult to break, so you don't have to worry about it.

Let's lift it and look...

We understand that we still need to disconnect the wi-fi module of our netbook. Two wires black and white. These are wires to the antennas that are located behind the screen.

After this, the board can be completely removed from the Asus EEE PC case. And remove the wi-fi module itself so that it doesn’t get in the way :)

That's all! The board has been dismantled and is ready for upgrading.
You can admire it:

Netbook motherboard asus eee pc 900 top view:

Asus eeepc 900 netbook motherboard bottom view:

blue round - bios battery
in the middle - ddr2 connector

Mysterious marks were discovered on the board itself, left to us by Chinese assemblers. The meaning of these signs has not yet been deciphered. :)

Interestingly, the cooler is located under the board and takes heat not from above the processor (as usual), but from below from under the board. I wonder if it's overheating?
There are speakers in the front of the case. In principle, this is perhaps the standard arrangement for them in most netbooks.

That's all. As soon as the bluetooth is soldered in, I will take more photos and continue the story about upgrading or tuning the Asus EEE PC 900.

Nowadays, almost everyone has a home. Personal Computer. Definitely, each person uses it at his own discretion - someone likes to sit and visit various Internet resources, including social media, someone plays games on a computer, and for others a PC is a means of earning money. Every user of this device knows that it is necessary to periodically look inside the system case and clean it of accumulated dust. This dust gets there thanks to the cooling system, which allows you to keep the temperature inside system unit fine. The dust accumulated there tends to contaminate the fans, which leads to the thickening of the oil on the moving axis and these fans begin to spin slower and slower.

Many people have a laptop, which in terms of functionality is indistinguishable from a personal computer. This computer is made using all-in-one technology in a miniature case. Do not think that this device does not need to be monitored and maintained, cleaned of dust and the like. Laptops love cleanliness and well-groomed just like a personal computer. Therefore, it is necessary to disassemble it every six months and clean it of accumulated dirt and dust.

Many people wonder how to disassemble a laptop. acer aspire, hp pavilion? The answer is very simple - unscrew all the bolts and open it. But everything is not done that easily. There is a possibility of damaging some parts, therefore, in this topic we will talk about how easy it is to disassemble a laptop.

We take our dirty device, which you want to disassemble for subsequent cleaning, and turn it upside down. Basically, there are various mounts for devices such as a hard drive, optical drive and much more. There is also a special compartment for replacing RAM and WiFi module.

Filming battery, unscrew absolutely all the bolts. Please note that the bolts may also be on the battery compartment. Therefore, if the lid cannot be opened freely, then look carefully at where you forgot to unscrew the bolt.

Before removing the laptop cover, pay attention to the devices that need to be removed first. This will be a hard drive, optical drive. The hard drive is removed by sliding. It has a special grip tape on it. You slide the hard drive and it detaches from the laptop.

You need to remove the optical drive, which is also removable. Sometimes it can be easily removed by unscrewing a special screw on the bottom of the laptop, but on some models there is a double-sided mount, that is, the drive is fixed on the keyboard side. If you can't easily release the drive from your PC, don't rush.

How to disassemble asus laptop, dell, toshiba, if dust has accumulated? The next step consists of disconnecting all the cables that connect to the back. It is necessary to remove various visible cables and cables, mainly the cooler cable and cables wireless communication WiFi. Be sure to disconnect the WiFi cable, as it is located along the display matrix.

So, having disconnected all the cables and cables that are there, you can remove the main part, which is a means of cooling the processor - the cooler. Often, over time the laptop is used, the lower part under the processor begins to heat up more and more - this indicates that the cooler has become weaker or a lot of dust has accumulated on its body, which does not allow air to enter the special exhaust slots.

Cleaning the cooler alone is not enough, so it is necessary to clean the entire cooling system - the radiator, its grids, as well as the radiator mounting on the processor. Be careful when removing the heatsink from the processor - unscrew the four screws and apply a little force to move the heatsink itself. A little effort is necessary because the old thermal paste may have dried out and needs to be replaced with fresh one, which can again restore heat transfer to the radiator.

Many people are interested in how to disassemble a laptop keyboard? Now, after the above procedure, you can turn the laptop over to its working position and begin removing the keyboard. Typically, the keyboard is attached to the case with special latches, and you can remove it by picking up the tab. If you don't find any protrusions, then your keyboard is most likely bolted under a special plastic surround. You must first remove this trim and unscrew the keyboard. After this it can be raised.

Now you need to disconnect all cables visible under the keyboard. It is imperative, first of all, to remove the keyboard cable itself, there is a risk of damaging it, so the keyboard must not be lifted immediately, but some part where you can safely remove the cable. All cables on the laptop are removed from the special mount by lifting the latch up or moving it to the side.

How to disassemble a laptop and clean it? There are very few operations left to disassemble the laptop. Now that the main closing elements have been removed, it is now necessary to remove the display. To do this, you need to look at where the cables from the matrix come from. Some laptop models have a special cover on the side, under which there are two cables from the matrix - one cable is responsible for supplying a signal to the matrix itself, and the second cable is responsible for backlighting the display itself. They need to be disconnected from the motherboard.

After these cables have been removed, you can begin to unscrew the covers that are connected to the display axis, and then under the covers, unscrew the remaining fastening bolts that strongly press the display to the axis.

Now you can carefully remove the cover with the display from the main part. If separating two parts from each other is difficult, do not make special efforts. You need to look carefully to see if there are any unscrewed screws left. Otherwise, you may damage the lid's axial rotation mechanism. In some laptop models there are no more bolts under the cover - the case is secured with latches. This model has bolts, which means you need to unscrew them.

So, we move on to the point - how to properly disassemble a laptop. After the above procedures, you can safely remove the top cover of the laptop. As mentioned earlier, there are latches on this housing, and in order to touch them and disconnect the upper housing from the lower one, you need to use an amateur radio spatula or you can use a screwdriver with a narrow end.

Now you need to remove the motherboard from the bottom of the case. First, take a closer look at the motherboard. You should notice all the screws on it and unscrew them. Next, look closely at the remaining connected cables. This may be a loop from the connected speakers and should be disconnected. On some models, external interfaces can be made separately and connected to motherboard through the loop. They should also be disabled. After all this, carefully remove the motherboard from the case.

Many people are interested in how to disassemble a laptop battery? There is no need to disassemble the laptop battery, and you cannot repair it. If you feel that your battery no longer holds the laptop as before, this means that some battery cells have exhausted their performance, and replacing these cells will not be so easy, because you can damage the battery case, which will then make it impossible to install it in the laptop. In this case, it is necessary to completely replace the battery on the laptop, and you need to look for exactly the same battery or order it from the manufacturer.

Now that the main part is disassembled, you can begin disassembling the display case. To disassemble the case, you need to remove special rubber plugs that serve as feet between the main body and the display. We carefully pull them out and see the bolts there. We unscrew the bolts and use an amateur radio spatula or a narrow screwdriver to run along the two display housings to release the latches.

With the display cover removed, you now need to detach the display itself from the bottom cover. The matrix is secured with several bolts around the perimeter. After unscrewing these bolts, you can see the inverter under the matrix.

Now, before removing the matrix, you need to disconnect the cable.

The disassembly of the laptop has come to an end. Now you can safely clean each part of the laptop individually. From the plastic case you can remove the electronic elements remaining on it, such as connectors, speakers and many others. After freeing the housing from electronic components, this housing can be washed with soap and warm water.

How to disassemble a laptop cooler and why is it necessary? Most often, the cooler may begin to lose airflow speed and then it is necessary to disassemble it. It is worth considering that not all cooler models can be disassembled.

Some cannot be taken apart at all without breaking it. Only replacement is required here. Those coolers that are disassembled have a hole on the back side behind the sticker, along the axis of which there is a special fastening plastic that holds the axis itself and does not allow the blades with the magnet to fall out of the coil. This plastic can be pulled out with a needle and then the blades themselves can be removed. After cleaning the axle and the blade itself, it is necessary to lubricate the axle with machine oil and reinstall it on the reel. Then you need to put the mounting plastic in place so that it holds the magnet with the blades. If cleaning and lubricating the cooler did not help achieve good results, then the cooler requires complete replacement.

How to choose a laptop
(2600)

An interesting observation: all over the world they are searching for the phrase “ How to disassemble a laptop"more than 17,000 people, but " how to properly disassemble a laptop» only 208! Paradox).

First of all I would like to point out that any practical use of this article - solely at your own peril and risk! Remember, it's better to ask or Google (and sometimes just think a little longer) than to try to do something you don't understand.

Disassemble the laptop it was necessary to find a bad place contact in the power circuit. For this purpose, it was removed (for study, tightening contacts and, if necessary, soldering in problem place) wiring harness with a connector for connecting the adapter, going to the motherboard. It is difficult to name the component for which extraction I would have to disassemble the laptop in more detail!

For those who are just disassembling a laptop, I advise you to start reading the article from bottom to top!

For this repair we will need a screwdriver(cross) (choose the size carefully using the screws) and a wooden or plastic plank, which you don’t mind periodically sharpening to the point of a chisel. A good option- disposable Chinese chopstick. It will practically be a consumable item.

When disassembling I recommend using small lockable ones containers for screws with signatures that clearly allow you to restore their purpose and location during assembly. Lockable, because there is a high probability that after disassembly something will distract from the process, and it will be necessary to assemble and pack the disassembled device until better assembly times, and also so as not to scatter the screws all over the area during some local cataclysm. Whatever is on hand will do. This time we had plastic Eppendorf tubes on hand:

First of all, install the connector into the housing and carefully lay out the wiring harness as shown in the photo. It is almost impossible to insert the connector itself incorrectly - its shape is quite unambiguous. After installation, we attach the grounding screw to the housing with orange conductive coating.

Now we put the left speaker in place and secure it with two carefully preserved screws.
Screws need to be delayed until a reasonable moment. It’s not worth making it too strong, “for centuries” - you can ruin the aesthetics of the screw slot, as well as deform the plastic. In addition, it will complicate the next possible disassembly.

Let's move on to the right loop of the monitor. Carefully lay the Wi-Fi antenna wire deep to the right of the right speaker, put the monitor hinges in their proper places and secure them with the appropriate screws.

The hinges are usually quite tight, so it is best to straighten them both at once and screw them together, placing the monitor body in the most comfortable position.

Views of the motherboard from below and from above, respectively:

When working with printed circuit boards It is extremely important to be careful with static electricity. Regularly equalize your potential and the ground potential on the board (by touching the metal connector housing on the side of the board, for example). This is especially true when using woolen clothes and/or concentrated fidgeting in a chair, which will be difficult to do without. Ideally, it is good to use an antistatic wrist strap.

We install the motherboard in its proper place (it is also quite difficult to place it incorrectly). Do not forget to be careful when its connectors or other parts rest against the laptop body. If excessive force is applied, the contact of these parts with the board may be disrupted. Bending deformation is also not beneficial to the board.

Carefully hide the monitor cable deep to the right of the left speaker and connect it to the corresponding connector. The arrows indicate where to connect the cable:

We work very carefully and “sensually” with fastening the connectors of cables and simple wires. Smoothly holding both parts, we slowly apply insertion force until a characteristic soft click is felt. Depending on the connector, it can be very soft and not very clicky, but you can feel it quite well, in my opinion. You don't need to use too much force, it could damage the connector's solder joint or something worse.
It is convenient to disconnect the cables with our homemade wooden chisel. Its shape is a tribute to your ingenuity and love of comfort. It is usually convenient for it to be about 5-10mm wide and sharp enough to fit into a narrow slot. Also, the wooden stick will not close the contacts when you accidentally touch the board with it.

The screws that need to be installed in the next step are shown with red arrows. Next we connect the cables of the Power button with the LED, as well as network card to the motherboard:

These two cables do not have a plastic connector at the end, but instead have a tab for easy removal. The tongue and cable, pressed against each other, form a structure rigid enough to be carefully inserted into the connector on the motherboard. With a sufficiently slow and careful application of force, you can feel that the cable has entered all the way. You can evaluate this by placing the end of the cable to the connector before inserting it and estimating the length to which it should go. Also, with some skill, you can carefully try to use only the tongue to insert the end of the cable into its proper place.

When we see during disassembly that there are many holes for screws, and only some of them are occupied at this stage, it is better not to be lazy and at least write down or sketch, or better yet, take a photo of this moment. Remembering such things can be difficult. For example, in the photo above you can see that of all the holes at this stage, only two require screws. The remaining holes imply through use with the top and/or bottom cover.

Now it's time to connect the expansion cards on the other side of the motherboard. Don’t forget to connect the connectors of the power wires, the battery board and the wi-fi antenna going into the monitor.

We insert the Wi-Fi card into its proper place in the mini PCI-E connector. Before doing this, we make sure that the contacts are clean. We do not touch the metal contact plates with our fingers. The card is secured with two screws.

We do the same with the modem. Its connector is vertical. Gently press it until you hear a characteristic smooth click. It is best to do this slowly to feel that the connector is fully seated. We also fix it with the corresponding screw from our “cash box”:

Now we put the optical drive in place. Its shape also leaves no doubt about the correctness/incorrectness of its placement. We insert the connector in the same way as we did with the network card, without touching the contacts. The drive should be pushed into the connector from right to left when looking at the open laptop in a natural way. We fasten it with a screw from the side back cover.

The next stage of assembly will be connecting and securing the top cover:

I would like to immediately draw your attention to the fact that the operation of removing this cover, in my opinion, is the most potentially dangerous for both breakage and damage to the appearance of the device. There are two things to remember when disassembling.
Firstly- after you have unscrewed all the imaginable and inconceivable screws that, in your opinion, hold the cover, you need to find where the plastic latches are located that can (and, most likely, will) hold it in addition to the screws. There can be two breakdowns here - either careless prying of the lid with something hard and flat, leaving unpleasant traces of “opening” the patient in the areas where the lower and top covers, or the latch can break off, which can lead to the joint being loose and cracks forming in it. Therefore, I recommend using a flat tool made of a material that is obviously softer than the material of the lids for prying. This can be a disposable Chinese stick, planed with a knife from the wide end to the state of a chisel, or a similar piece made of soft plastic. I recommend making this “tool” by hand, because due to its softness, it doesn’t last long, after which it needs to be resharpened. However, this is a price to pay for the aesthetic pleasure of the joint in the case after assembly (if there was one in the first place). Once one side of the lid remains, which is held only by the latches, it is useful to rock the lid up and down, thereby carefully freeing it from their grip. At this moment, the main thing is not to rush, because it is one of the most “traumatic” for the person being repaired.
Secondly- as a rule, there are cables from the cover to the motherboard, the connectors of which can be located approximately in the center of the motherboard. It is quite easy to damage them in various parts. Therefore, after the cover has given way, carefully look under it, find out how and how it is connected to the motherboard in order to carefully disconnect it, without bringing the cables to critical deformation when lifting the cover.

In this case, the cables to the motherboard are quite accessible without lifting the cover.
By the way, Toshiba carefully indicated the markings of the screws for convenience. The presence of such markings (F number) on an empty thread also indicates that a screw needs to be tightened on this layer of the assembly.

Among the fastening cables there are connectors with a folding plastic clamping strip:

We fold it back for installation, place the end of the cable clearly in the shallow recess for it (fix it in the transverse direction), and then insert it approximately along the dimples on the cable from the previous clamp. We close the plank. A correctly clamped cable should hold quite tightly. If it is removed, then you need to once again carefully and correctly position the cable in the recess for it and deepen it into the connector to the end before snapping it into place. Patience and accuracy when connecting cables will pay off when you don’t have to disassemble a fully assembled device again, because some of the equipment on board will not work (in this case, the touchpad or the lights on the case, or the buttons for the player above the keyboard, for example).

It is convenient to place the keyboard by tilting it towards you. Then it will be easy to connect the cable. Its connector is also equipped with a folding bar:

The keyboard is often secured with latches on the sides. In our case, they are below and above (the lower ones are marked with arrows). There are still two screws on top (above the F1-F2 and END-INS buttons). The area above the keyboard is covered with a white plastic strip that simply snaps into place.

After snapping the plastic strip over the keyboard, the top of the case is ready.

Now let's go back to the bottom cover. Install the screws as in the photo:

We put the hard drive in place. As always, carefully and gently (and most importantly - to the end) we combine the connectors. There is no need to screw in the disk housing fixing screws yet.

A line of remaining screws on the back cover. Compartment cover screws hard drive The disk itself is fixed in the body of the laptop. Finally, close and tighten the three screws of the central memory compartment, modem and network card.

All that remains is to install the battery, remove the bandages and check the functionality!

After everything has loaded successfully and there are no visible problems, it’s good to go into the device manager in Windows or lspci and its ilk in Linux or system information on Mac to make sure that the peripheral is successfully recognized and is working. After successfully passing the test, you can finally exhale, relax and enjoy the integrity of the device, which was just distributed in an even layer on the table and boxes, and is now breathing life.

If possible, carry out work on a clean, flat surface, free of small abrasive particles. Rolling on the table is inevitable, so the patient's body may be scratched. From an uneven surface, small parts will always strive to run down.
Handle screws carefully and pack them in secure containers so they can be fast packaging[semi]disassembled device until better times of assembly. The likelihood of procrastination is quite high, and, in my opinion, this is a good habit.
Be careful about documenting the disassembly process. Best of all, take a photo. If you don’t take pictures, then write them down and sketch them. The specificity of the repair is that we return to assembly, sometimes much later than planned. Something is distracting or missing in this moment moral strength - everything should be ready to resume repairs after a while >> time, when you even more or less remember the order of screwing in and the purpose of the screws. Write down/mark specially not noticeable moments, such as a poorly visible disconnected cable.
When working to separate plastic parts, resist the temptation to use a flathead screwdriver or a knife. Use dielectric (if electronics are nearby) tools that are softer than the parts being separated. The same applies to the disconnection of thin metal connections, where it is important to keep the appearance. A planed disposable Chinese chopstick is an excellent candidate.
Be aware of electrostatic hazards. Do not touch parts of the boards with metal objects (such as tweezers) and do not bring them close. It is better not to use metal tools at all except a screwdriver. Regularly touch a safe solid metal part of the device, such as the connector housing, with your hand and a screwdriver to equalize the potentials. Or use an antistatic wrist strap.
Be gentle, kind and considerate with connectors. Remember the “science of contacts.” In my opinion, a huge number of problems can be avoided by being careful when connecting connectors.
Try to understand the purpose of this or that cable, keep track of where it goes, what it connects. Manifest Special attention, if, in your opinion, something looks illogical. Don't wave your hand at such a moment. This is your chance to upgrade your level of understanding, your ability to understand, and with them the general experience that is so necessary when solving more complex problems.
In my opinion, patience, desire and a reasonable approach can work wonders in repairs, even if you have not yet accumulated any experience. Don't be afraid to explore an unknown problem. With a careful and patient approach, you can stop in time when faced with an unknown/unsolvable problem and take reversible (that's what neatness is for) steps in reverse order, at least ending up where you started.

Instructions for disassembling and servicing laptops

Select your laptop manufacturer

According to our instructions, you can do:

Disassembling and cleaning a laptop fan- will help prevent overheating of the cooling system, this is considered the most common problem that leads to serious damage to the motherboard.
Replacing thermal paste in a laptop- it is recommended to change the thermal paste once a year, this allows you to reduce the temperature of the processor and thereby increase performance.
Replacing a laptop keyboard- one of the most common laptop breakdowns due to liquid ingress.
Replacing a laptop screen- the display is one of the most fragile elements of a laptop and if it breaks, it is impossible to restore the liquid crystal display; there is only one way out - replacement.
Replacing the hard drive- The HDD in a laptop is the most fragile part; even with a slight fall it breaks down. In many cases, repairs are very expensive, but replacement is not difficult. Also, according to the instructions, you can replace the old and slow hard drive with a new and fast SSD drive.
Replacing or adding RAM to a laptop- one of the most common ways to add performance to a laptop, just like installing an SSD drive.
Replacing the battery in a laptop- if your laptop has a battery in the case and there is no possibility of quick replacement, according to our step by step instructions you can change the battery in your laptop.
Assembling a laptop- reassembly after completed tasks is a decisive factor that discourages many from disassembling. For each laptop disassembly instruction, there is a reverse assembly that will help reassemble the laptop to its original state.

Answers to frequently asked questions about laptop servicing

Is it possible to clean the laptop yourself or is it better to take it to a service center?

In fact, anyone can clean a laptop themselves. For those who have not done this before, it may seem like something very difficult, but if you don’t do everything in a hurry and are aware of what is being done and why, nothing terrible will happen. In any case, these two options have their advantages and disadvantages. Cleaning a laptop yourself is free, allows you to control the entire process, saves time, but it requires tools and consumables in the form of thermal paste, and there are always risks associated with a lack of experience or accuracy. Cleaning in the service, on the other hand, is carried out by competent people with sufficient experience (at least this should be the case), the disadvantages do not end with the cost of cleaning the laptop, it is also worth considering the risks associated with the incompetence, dishonesty of the craftsmen and it takes more time.

How often should you clean your laptop?

The simplest answer is as often as required by the cooling system. To be precise, cleaning is needed when the efficiency of removing excess heat decreases. This is when cleaning your laptop fan will have a noticeable effect. To make it even easier to control this, you can do this: in a laptop that has been cleaned of dust, at the moment of load, when the cooling system is working intensively, put your hand on the place where the air is blown out of the case and approximately remember the force of the air blowing, and then use this as a standard - if you feel that the laptop has warmed up and the fan is running at full capacity, but the blowing feels very weak - this means the time for cleaning has come.

Do I need to change thermal paste when cleaning my laptop from dust?

In general, there are two sure cases when replacing thermal paste is mandatory:

When cleaning, the cooling system (heat pipe) was removed; in many models it is necessary to remove the entire cooling system in order to clean the fan and radiator from dust. In this case, it is necessary to change it simply because if the thermal paste has lost its original viscosity, it will not fit back normally, that is, it will not fill the space between the chip crystal and the cooling system plate, therefore, excess heat will be less efficiently transferred to the cooling system.
It can be easily characterized by simple symptoms: the laptop heats up noticeably (you can feel it directly with your hand on the case), the cooling system blows at full speed, blowing out air strongly, but the air blown out is barely warm. Similar symptoms may occur when the thermal tube itself of the cooling system fails, but this does not exclude the possibility of dried out thermal paste.

It is allowed not to change the thermal paste only in cases where the fan in your laptop can be removed without removing the thermal tube and you do not have thermal paste on hand, in this case, simply clean the radiator from dust with a brush.

What is the best thermal paste for a laptop?

Thermal paste for the processor and methods of applying it, the topic is so hackneyed that only the lazy kicked this topic. But to put it simply and without unnecessary fluff - by bad I mean the KPT-8, beloved by “bad service providers,” for example, or a bunch of no-names from Aliexpress (although this is more of a lottery). And among the worthy options, the difference is not so big, for example: Noctua NT-H1, Arctic MX-4, GD900 (despite the price), HY810 (despite the inferiority of others in the series). Well, then everyone can see for themselves which ones they have, judging by the tests. Thermal paste for a video card is the same as for a processor; it does not have any additional nuances.

How to Apply Thermal Paste to a CPU

The most reliable way is to apply in small drops, then manually spread these drops in a thin, even layer over the surface of the chip (but please do not do this with a screwdriver or other metal tool, only plastic). And the basic principles on how to apply thermal paste correctly and how much thermal paste to apply can be determined as follows:

The thermal paste should fill all the free space between the surface of the chip crystal and the thermal plate of the cooling system.
There should be enough thermal paste to fill this space.
When fixing the cooling system, excess thermal paste in a laptop is squeezed out beyond the area of the chip crystal.

Is it possible to replace the processor in a laptop with a more powerful one?

Taking into account modern realities, it is very rare when a laptop uses a socket and the processor can be removable. A little earlier, a few years ago, processors in laptops were removable, and then an upgrade within the socket and chipset version was acceptable. Now everything mobile processors They are soldered onto the motherboard, and replacing them, even if possible, is not advisable. Well, with video cards in laptops, this has been the case for quite a long time, and there is practically no opportunity to replace the video card in a laptop, only in some game series Asus type Rog or Alienware.

How to increase laptop speed

The universal answer is simple - by improving the weakest node of the system, if such an improvement is of course possible. Most often it will help SSD installation in place of a basic hard drive, since the latter in most cases does not keep up with the speed of the processor (system loading, programs), and this rule does not work except with really weak processors, most often these are processors of the Intel Celeron, Pentium, AMD A4 family, A6.

Increasing RAM will help a little less often. Will the installation help the easiest way by following average level filling your volume in the task manager resource monitor, if the average load per eye is about 80% - most likely, after adding RAM, the laptop will become much more pleasant to use. But there is also an important nuance here - not every laptop has the ability to add RAM, which is especially true for budget series, where sometimes there are no memory slots at all.

Is it worth repairing a laptop yourself?

It is difficult to answer this question unambiguously. On the one hand, lack of experience is a very significant thing, and if you have never had to disassemble a laptop yourself before, it seems that the device is complex and incomprehensible. On the other hand, most people, today called “service workers,” by their very existence are the best motivation to learn how to carry out at least basic repairs themselves. The reason is actually simple - in most cases, the service is staffed by crooked self-taught people who are interested not so much in repairs, but in how to do it quickly and earn money. Naturally, not everyone is like this; there are also craftsmen who love their work and know how to do it, but unfortunately, now they are in the minority. This is actually the main reason why do-it-yourself repair takes place. Other benefits: experience gained, money saved, time and nerves.

As for the repair itself, it is more often simple than complex: replacing the battery, accumulator, power socket, hard drive or even matrix yourself is not difficult. Well, if the repair is complex, it is unclear what is broken, for example, then the very fact that such a question arises suggests that you will take risks and look for a normal service center.
