Home »How to disassemble a laptop Lenovo G500 and G510 to clean the dust?

Somehow they brought me such a laptop and asked to carry out preventive maintenance and cleaning of the cooling system. The customer complained about the laptop overheating. At first I thought, they say, this is a Lenovo laptop, on some laptops of this company, in order to get to the cooling system, you literally have to disassemble the entire laptop. To scatter it into small components. And over time, and so an ambush. Sea orders. But it turns out that I was deeply mistaken. Apparently, this laptop model is a pleasant exception. To get to the cooling system, you will have to disassemble the laptop only partially, mainly from the bottom of it. Well, this is all the lyrics, let's proceed to the disassembly and cleaning of the laptop itself.

This epic begins as usual. Turn off the power to the laptop. We take out the battery from the case, pushing back certain latches. The clips are shown in the photo, so you can't go wrong.

There is a cover on the bottom of the laptop, it is almost the size of the entire free area of the bottom of the laptop. To remove the cover, unscrew the two screws shown in the photo. The screws are located in the compartment where the battery was not so long ago.

Having unscrewed the necessary screws, we move, and then remove the cover. Look at the picture below.

Under the lid, we will see the ramps, hard drive and several other important elements of the laptop. It was decided not to touch the operative memory. The Winchester, in principle, should also not prevent us from getting to the laptop cooling system in order to clean it of dust and replace the thermal paste on it. But at first, I did not know this, and the hard disk was still removed. And I will also tell you how it is done, if it will be useful to someone in the future. Unscrew the two screws and pull the hard drive in the direction indicated by the red arrow in the picture. This will disconnect the hard drive from the connector. Then, lift up one end of the hard drive and slide it out of the laptop.

It also gets rid of the optical drive. Just in case, so to speak. We unscrew the screw that secures the drive. Then, push the drive out of the housing and remove it completely.

Removing the cooling fan... To do this, unscrew a couple of screws and disconnect the wiring that supplies power to the cooling fan. Occasionally this wiring may be stuck with adhesive tape, so pay attention to this.

Moving on to removing the cooling system from the laptop motherboard. Unscrew the screws that are marked in the bottom picture. Remove the cooling radiator. You can start cleaning the cooling radiator and removing the old layer of thermal paste from the contact pads. Before installation, we will apply new thermal grease.

In order to clean the cooling fan from dust, it was decided to disassemble it into smaller fragments. Thus, the fan can be cleaned more thoroughly and will be much more convenient.

I will not tell you how to clean this or that part of the laptop. There is nothing complicated here, especially since everyone is used to doing it in their own way, using certain tools and devices.

After cleaning all the elements of interest to us, we proceed to assembling the laptop. Since the disassembly process did not take much time and, in general, was not difficult, you can put the laptop back together without any particular difficulties.

How to disassemble a laptop Lenovo G510, G500 and clean it yourself from dust / disassembly. How to replace HDD, RAM)

Today they brought me a Lenovo G510 laptop for repair.This "poor fellow" fell from the table to the floor, and he was covered with something sticky, perhaps beer or kvass. Now I will tell you how to disassemble it.

We turn the laptop upside down, so that the battery is closer to us. We then extract this power supply.

Next, you need to unscrew the cover that covers the bottom of the laptop. In this line of mobile PCs, the manufacturer refused to use a large number of screws to fix the back cover of the device. The four protuberances found in the four corners of this laptop function as legs; there are no fasteners underneath.

The back cover is held in place by just two screws, which are located on the longest wall of the battery compartment. You need to unscrew these two screws. I first removed the seals that covered the screw heads, and later I will tell you why I did it.

After the screws are unscrewed, you need to slide the laptop cover away from you, and it can be easily removed.

On its inner surface, you can easily see traces of the liquid with which this mobile computer was poured. Then we rotate the laptop so that the battery compartment faces forward.

As you can see, this laptop no longer has a hard drive - I removed it earlier, as the owners urgently needed it, because this hard drive contains information that is of great importance for the owners of this device. Despite the lack of a hard disk, I will try to explain the very principle of dismantling it. To remove the hard drive, you need to unscrew the two screws securing it to the right and left. When the screws are unscrewed, you need to pull the hard drive towards you and remove it with a sliding motion.

Then remove the optical drive. It is secured with exactly the same screw as the hard drive.

Then you need to dismantle the keyboard, which is fastened with three screws. If you draw segments between the heads of these screws, then they form an isosceles triangle. The two vertices of this triangle (screw heads) are in the immediate vicinity of the battery bay, and another screw is located near the upper left corner of the hard drive bay. Note that the screws that secure the keyboard are different from the screws that hold the back cover and laptop hard drive, and should not be confused when reassembling.

Then we need to dismantle the cooling system. We unscrew the screws securing the fan, they are smaller in size than those that we have seen before.

We remove the fan, but something does not allow us to do this - the power cable is attached with adhesive tape, it is she who holds the cooler. We peel off this tape, and the fan is released.

Then you need to unscrew the radiator. We unscrew the three spring-loaded screws that hold the processor, and unscrew two more screws that are located on the left side of the cooling system.

We remove it, blow it through and clean it, also change the thermal paste.

In the next part of the article, you can learn how to dismantle a keyboard in a Lenovo G500 laptop, remove an optical disk, a motherboard, and reassemble the laptop.

Below is a video instruction for a complete disassembly of the Lenovo G510 laptop.

All laptops have roughly the same design and the disassembly process is not much different. However, each model from different manufacturers has its own nuances in the assembly, connection wires and fastening of components, so the dismantling process can cause difficulties for the owners of these devices. Next, we will take a closer look at the process of disassembling a laptop model G500 from Lenovo.

Do not be afraid that during disassembly you will damage the components or then the device will not work. If you do everything strictly according to the instructions, perform each action carefully and carefully, then there will be no malfunctions after reassembly.

Before disassembling the laptop, make sure that the warranty period has already expired, otherwise the warranty service will not be provided.If the device is still under warranty, it is better to use the services of a service center if the device malfunctions.

To disassemble, you only need a small screwdriver that fits the size of the screws used in the laptop. However, we recommend that you prepare colored labels or any other markings in advance to avoid getting tangled in different screw sizes. After all, if you screw the screw into the wrong place, then such actions can damage the motherboard or other components.

The entire disassembly process must be carried out only with the laptop disconnected from the network, therefore, it will be necessary to completely limit all power supply. This can be done as follows:

Turn off your laptop.
Unplug it, close it and turn it upside down.
Spread the fasteners and remove the battery.

Only after all these steps can you proceed to complete disassembly of the laptop.

You may already have noticed the missing visible screws on the back of the Lenovo G500, as they are hidden in less obvious places. Follow these steps to remove the back cover:

"M2.5 × 6"

The other four screws that secure the back cover are located under the feet, so you will need to remove them to gain access to the fastening elements. If you disassemble it often enough, then in the future, the legs may not reliably hold in place and fall off. Unscrew the remaining screws and mark them with a separate label.

You now have access to some of the accessories, but there is another access panel that will need to be removed if the top panel needs to be removed. To do this, find five identical screws around the edges and unscrew them one by one. Be sure to also tag them with a separate label so you don't get confused later.

The processor is hidden under the cooling system, so to clean the laptop or completely disassemble it, the fan with a heatsink will need to be disconnected. This can be done as follows:

Pull the fan power cable out of the connector and remove the two main screws securing the fan.

Now you need to remove the entire cooling system, including the radiator. To do this, loosen the four fastening screws one by one, following the numbering indicated on the body, and then unscrew them in the same order.

The radiator is attached to an adhesive tape, so it must be disconnected when removing. Just put in a little effort and it will fall off by itself.

After performing these manipulations, you get access to the entire cooling system and the processor. If you just need to clean the laptop from dust and replace the thermal paste, then you can skip further disassembly. Follow the required steps and collect everything back. For more information on cleaning your laptop from dust and replacing the thermal paste of the processor, read our articles on the links below.

The easiest and fastest action is to disconnect the hard drive and RAM. To remove the HDD, simply unscrew the two mounting screws and carefully remove it from the connector.

The RAM is not secured in any way, but simply plugged into the connector, so simply disconnect according to the directions on the case. Namely, you only need to lift the lid and get the bar.

On the back of the laptop there are a few more screws and cables that also hold the keyboard. Therefore, carefully look at the case and make sure that all fasteners have been unscrewed. Remember to label the different screw sizes and remember their locations. After completing all the manipulations, turn the laptop over and follow these steps:

Take a suitable flat object and pry up the keyboard from one side. It is made in the form of a solid plate and is held with latches.Do not use too much force, but rather walk with a flat object around the entire perimeter in order to detach the fasteners. If the keyboard does not respond, check again that all the screws on the back have been removed.

Do not jerk the keyboard, as it is held on to the loop. It must be disconnected by lifting the cover.

The keyboard is removed, and under it there are several cables of the sound card, matrix and other components. To remove the front panel, all of these cables will need to be disconnected. This is done in a standard way. After that, the front panel will simply detach, if necessary, take a flat screwdriver and pry the fasteners.

This completes the disassembly process for the Lenovo G500 laptop, you got access to all the components, removed the back and front panels. Then you can perform all the necessary manipulations, cleaning and repair work. Assembly is carried out upside-down.

Lenovo G500 (LA-9632P Rev 1.0) - Laptop Does Not Start
Good day! They brought a laptop Lenovo G500 with a diagnosis - not.

Lenovo g500 won't turn on
Hello. Help. I have a lenovo g500, I installed the unlocked one on it.

A laptop is a complex and sophisticated mechanism that breaks down periodically, respectively, without any of those. preparation and special skills are better not to fit. Laptops have always been difficult to disassemble due to the multitude of cable bolts, and other tsyatsek. Before you personally start disassembling your Lenovo laptop, we strongly recommend that you be patient and study the video source - “Lenovo laptop repair“So as not to spoil anything by stupid negligence and inexperience.

If you do not understand something, then scroll through the video again. Enjoy your self-study and may your own laptop never fail.

Is your TV, radio, mobile phone or kettle broken? And you want to create a new topic about this in this forum?

First of all, think about this: imagine that your father / son / brother has an appendicitis pain and you know from the symptoms that it is just appendicitis, but there is no experience of cutting it out, as well as the tool. And you turn on your computer, access the Internet on a medical site with the question: "Help to cut out appendicitis." Do you understand the absurdity of the whole situation? Even if they answer you, it is worth considering factors such as the patient's diabetes, allergies to anesthesia and other medical nuances. I think no one does this in real life and will risk trusting the life of their loved ones with advice from the Internet.

The same is in the repair of radio equipment, although of course these are all the material benefits of modern civilization and in case of unsuccessful repairs, you can always buy a new LCD TV, cell phone, iPAD or computer. And for the repair of such equipment, at least it is necessary to have the appropriate measuring (oscilloscope, multimeter, generator, etc.) and soldering equipment (hairdryer, SMD-hot tweezers, etc.), a schematic diagram, not to mention the necessary knowledge and repair experience.

Let's consider a situation if you are a beginner / advanced radio amateur soldering all sorts of electronic gizmos and having some of the necessary tools. You create an appropriate thread on the repair forum with a short description of “patient symptoms”, ie. for example “Samsung LE40R81B TV does not turn on”. So what? Yes, there can be a lot of reasons for not switching on - from malfunctions in the power system, problems with the processor or flashing firmware in the EEPROM memory.
More advanced users can find the blackened element on the board and attach a photo to the post. However, keep in mind that you are replacing this radio element with the same one - it is not yet a fact that your equipment will work. As a rule, something caused the combustion of this element and it could “pull” a couple of other elements along with it, not to mention the fact that it is quite difficult for a non-professional to find a burned-out m / s. Plus, in modern equipment, SMD radio elements are almost universally used, soldering which with an ESPN-40 soldering iron or a Chinese 60-Watt soldering iron you risk overheating the board, peeling tracks, etc. The subsequent restoration of which will be very, very problematic.

The purpose of this post is not any PR of repair shops, but I want to convey to you that sometimes self-repair can be more expensive than taking it to a professional workshop. Although, of course, this is your money and what is better or more risky is up to you.

If you nevertheless decide that you are able to independently repair the radio equipment, then when creating a post, be sure to indicate the full name of the device, modification, year of manufacture, country of origin and other detailed information. If there is a diagram, then attach it to the post or give a link to the source. Write down how long the symptoms have been manifesting, whether there were surges in the supply voltage network, whether there was a repair before that, what was done, what was checked, voltage measurements, oscillograms, etc. From a photo of a motherboard, as a rule, there is little sense, from a photo of a motherboard taken on a mobile phone there is no sense at all. Telepaths live in other forums.
Before creating a post, be sure to use the search on the forum and on the Internet. Read the relevant topics in the subsections, perhaps your problem is typical and has already been discussed. Be sure to read the article Repair strategy

The format of your post should be as follows:

Topics with the title “Help fix the Sony TV” with the content “broken” and a couple of blurred photos of the unscrewed back cover, taken with the 7th iPhone, at night, with a resolution of 8000x6000 pixels are immediately deleted. The more information you post about the breakdown, the more chances you will get a competent answer. Understand that the forum is a system of gratuitous mutual assistance in solving problems and if you are dismissive of writing your post and do not follow the above tips, then the answers to it will be appropriate, if anyone wants to answer at all. Also note that no one should answer instantly or within a day, say, no need to write after 2 hours “That no one can help”, etc. In this case, the topic will be deleted immediately.
You should make every effort to find a breakdown on your own before you get stumped and decide to go to the forum. If you outline the entire process of finding a breakdown in your topic, then the chance of getting help from a highly qualified specialist will be very great.

If you decide to take your broken equipment to the nearest workshop, but do not know where, then perhaps our online cartographic service will help you: workshops on the map (on the left, press all buttons except “Workshops”). You can leave and view user reviews for workshops.

For repairmen and workshops: you can add your services to the map. Find your object on the map from the satellite and click on it with the left mouse button. In the field “Object type:” do not forget to change to “Equipment repair”. Adding is absolutely free! All objects are checked and moderated. A discussion of the service is here.

repair of computer technology ...

Thanks a lot. One of the bolts had a seal with the inscription Lenovo, and
hieroglyphs ... it looked like there was an inscription about the loss of warranty in case of damage
seals .. but how to add memory? is it really only through the service?

I'm trying to see if it supports putting in a Back-lit Y500 keyboard. Does
it?

Good afternoon, what is this music playing? Thank you

Good afternoon. Nice to look at the work of the pros. At my exit on
headphones, the left channel does not work, but on the speakers everything is ok.
Can I replace it myself? Or can there be difficulties when soldering?

can you tell me how to reset the BIOS? if you can't get close to me

Oh, thanks for the video! In time. Only here is the question - is it possible on the G500 a matrix
replace without completely removing the display and without unscrewing the filling to the screws?
The display frame is simply snapped off and then the matrix itself is unscrewed and
the loop is disconnected? Or not?

For repairs and maintenance, it is often necessary to disassemble a laptop. For example, we needed to disassemble the Lenovo G500 laptop. Originally the design of this laptop is a little confusing - when you turn it over, you realize that there is not a single screw on its back that would fix the structure of the laptop and which (s) could be unscrewed to carry out work on disassembling this laptop. But experienced craftsmen will not be confused by such a trifle. Actually, we assumed that the screws that secure the laptop cover are hidden behind the laptop battery. And so it happened. Lenovo is very fond of using this design, and other manufacturers also often resort to this scheme of fastening and assembling a laptop. Actually, there are no complaints about this mounting scheme - everything is securely fastened and you only need 2 screws for this.

And now everything is in order and with photos.

How to disassemble Lenovo G500 laptop for service or repair

If you turn the laptop over, it turns out that there is not a single screw securing the structure.

However, the battery pack can be removed. Which is what we are doing. The arrows below in the photo show the direction of movement for removing the battery pack.

After the battery has been successfully removed, we carefully examine the end face of the space that has opened behind the battery and we see there two fixing screws.

Where to look for the screws can be clearly seen in the photo below. Their approximate position is marked with red arrows.

Actually, in the photo below, the places where the fixing screws are located are just marked.

After the screws are safely removed, we return the laptop to a horizontal position and remove the cover. The direction of pressure on the cover is indicated by the arrows in the photo below.

Disassembling Lenovo G500 - remove the cover

After performing the above simple manipulations, you gain access to all components of the Lenovo G500 laptop.

We disassemble Lenovo G500 - everything is ready - there is access to laptop components

Below we will not describe further manipulations on the complete disassembly of the laptop. On the one hand, not everyone needs this (already there is access to most of the components), and on the other hand, if it is necessary, then we simply continue to methodically and slowly unscrew the screws.

We hope our little material on disassembling the Lenovo G500 laptop helped you.

P.S. - be careful when you further disassemble the laptop.

There is no need to apply force in the parsing process. If you do not understand further, then you missed some kind of fastener, which must be removed, fixed.

In the event that your laptop is out of order, but you have neither the desire nor the need to disassemble and repair it, you can contact the purchase of laptops in Krasnodar and sell your failed laptop there.

If you are starting to disassemble a laptop for the first time, we recommend that you pay attention to the article “when starting to repair a laptop for the first time". This article provides guidelines to help you avoid common mistakes during the disassembly process.

If the laptop overheats during operation and shuts down abruptly, this is most likely due to overheating of the cooling system. This is due to the accumulation of dust on the radiator. If you do not clean the cooling system in time, this will lead to damage to the motherboard in the laptop.You can fix this problem yourself by repeating all the steps shown in the video below. The information provided in our video instructions makes it possible to clean the laptop from dust yourself at home. The necessary repair tools can be purchased at the end of the page.

Repair of the keyboard in most cases is caused by spilling tea or coffee on the surface, and as practice shows, there are two options for the outcome:

Remove the keys from the keyboard and clean their mechanisms with distilled water or alcohol, using a brush.

Replacing with a new keyboard (if cleaning the buttons did not help), then the liquid got on the lower layers with films where the tracks are located.

If it's not a secret, how much it will cost the client to repair a laptop with a nonsense breakdown in Toronto, for example, the laptop does not turn on, the logic flew for 0.15 cents.

Come on, old laptops are such laptops. Quite recently, for the sake of fun, I picked up an ancient JetBook (386).
It really does not have enough spare parts, it does not start. Found through which legs of the chipset the reset goes. It reaches the trigger and then hangs in the air.
If it starts up with tweezers, but the video memory is buggy, the screw doesn't really work. In short, a difficult case.

Just do not think that he plowed for so much time and therefore deteriorated. I was just lying in the trash for twenty years.

To get a discount - repost below
