This article is about my laptop. HP COMPAQ Presario CQ61.
Let me start by saying that I have been using it for about 3-4 years. Recently, he began to get very warm, especially when you play computer games. Often the thermal protection worked and it turned off. It got even worse when I got a job in a furniture factory with my laptop. Machine tools worked around the clock in the workshop and small wood particles in the form of dust and sawdust flew in the air. All this garbage clogged the radiator and cooler for 6 months. As a result, the laptop began to heat up so much that even cook scrambled eggs on it, but it made noise like a Soviet “rocket” vacuum cleaner.
I need to disassemble the laptop, blow out the radiators, clean the cooler, a friend told me and offered his services for 1.5 thousand rubles, but a toad strangled me and I decided to do everything myself 🙂
that day came, I woke up with a clear plan in my head - to disassemble my laptop! He poured himself some tea, sat down opposite the patient and remembered how in childhood he loved to disassemble and assemble everything, but only after assembly there were extra details 🙂
1. First of all, I got into the toolbox, started looking for various Phillips screwdrivers, one of them fit perfectly. We turn the laptop over, pull out the battery, unscrew all the screws.
2. Remove all plastic plugs and see if there are any other screws inside that can hold the plastic case of the laptop. In my case, there was nothing, I found only 5 screws under the battery. One of the screws holds the CD drive, if you have unscrewed all the screws, then try to pull out the CD-ROOM, it just pulls out like on a sled. Pull out the CD-ROOM - you can look inside :).
3. At this stage, I thought that the top of the laptop would open conveniently, I would blow the cooler and that would be the end of it, but no. I poked around with a screwdriver for a long time, the plastic latches slowly opened, I was on my way to success. But then I realized that the case was held by a few more screws somewhere in the middle of the laptop. After sitting and thinking, I realized that somehow I need to remove the keyboard. He put his hand in the place where the CD-room stood and tried to gently press on the keyboard from the inside. The keyboard was latched, with a slight physical impact, the upper part of the keyboard was completely unfastened, and the lower one sat in the grooves from which it later came out.
4. I pulled out the keyboard with grief in half, now I see that it is connected to the motherboard. Here, too, I hesitated for a couple of minutes. The first thing I did was try to remember what goes where, although there is nothing complicated and it is impossible to confuse. The problem was that I couldn't disconnect it 🙂 And all I had to do was pull the black lock and the cable can be disconnected very easily.
5. Well, all the keyboard is disconnected, hooray! Oh, how many crumbs and debris fell out of the keyboard. Rubbed / cleaned it with a damp brush, now it looks like new, not like in the photo 🙂
6. Opa, I immediately see a few screws, which means who held the rest of the case. Let's open it up and check it out!
7. Here you go, another piece of plastic has detached, it also has a cable to the motherboard, which is responsible for turning the computer on / off and for the Internet wi-fi. The train comes from those two buttons in the middle. Here, too, you need to remember where this cable is connected. Nothing complicated, in principle you will not get confused. If you forgot, you can simply attach this part to the laptop and see where the cable will lie.
8. Here is a closer photo. Do not forget about the little black latches that need to be pulled back and the cable will easily detach.
9. Okay, 2 parts have already been removed, and here it is the main piece of plastic under which all the insides are hidden 🙂 I also suffered with it. the latches near the touchpad did not want to open in any way (in the middle - mouse control). With a little pressure, the upper case completely detached.
10. Raise the case to the top. It was not possible to remove the plastic to the side, the power wires coming from the monitor interfered. I didn’t deal with them anymore, as I got to my goal, namely the cooler (orange arrow in the photo below). Looking into the cooler, I saw a kilogram of dust, wool, hair. All cleaned, blown, rubbed.
After I started to panic, how to collect everything back. Decided to calm down, went for some more tea, then came back and collected everything. Turned on the computer and voila - it works 🙂
It stopped basking, no longer makes noise and works like new! 🙂
If you decide to disassemble the laptop, here is my advice: the main thing is not to rush, inspect everything carefully, if something does not open, do not break, look, twist and see either a screw or a latch.
HP G62-b51SR- This is a rather old laptop model, which today has already been discontinued and is not sold in various electronics stores. But, despite this, at one time this laptop was successfully sold, and I am sure that a lot of users still use it.
But, as you know, no matter what the laptop is, it still collects dust over time, which periodically has to be removed from it. It’s just that if you don’t do this, then in the future there may be problems associated with overheating, laptop braking, or with uncharacteristic cooler noise.
So, just this article is intended for you dear owners of HP G62-b51SR and other models from this series. In general, below you will find step-by-step instructions on how to completely disassemble the HP G62-b51SR laptop and clean it from dust.
You must understand that you perform all further actions solely at your own peril and risk, but if you strictly follow the recommendations that will be described below, then you should succeed.
Stage 1: Disassembly of the bottom of the laptop
As usual, when disassembling a laptop, the first thing to do is to disconnect it from the power supply and switch the latch to the “ Open» remove the battery.
Next, on the bottom cover of the laptop, unscrew all available screws. For more information, in the example below, large bolts will be indicated in green, those that are medium in size in red and small ones in yellow.
I emphasize that you should remember their location otherwise, screwing one of the large bolts in the wrong place can damage the laptop case. Damage may not be critical, but it will still be very unpleasant.
So, removing all the screws, remove the covers hard drive and RAM.
Under the cover you will see:
- HDD;
- RAM;
- WiFi adapter;
- CMOS battery;
If you need to replace any of these elements, then you can do it right now by replacing the old ones with new components and assembling the computer back. If you decide to completely clean the laptop from dust, then we should completely disable all these elements.
In order to disconnect HDD, when disassembling the HP G62-b51SR laptop, you should first use the tab to remove it from the socket by pulling it up. And only then, when it is in your hands, disconnect the SATA connector.
After you disconnect the connector from the hard drive, I recommend that you disconnect it on the motherboard, again, using the tab, gently pull it up. Otherwise, in the future, when disassembling and cleaning the laptop, it will only interfere with us.
You can turn off the RAM only after you release it from the side mounts by pushing them apart. After that, without problems, remove the bar from the socket.
When disconnected WiFi adapter, you should first remove the two connectors, which then, when re-fetching, it is recommended not to confuse and connect them correctly. Usually there are designations on the connectors themselves and the Wi-Fi module, it can be a number or some symbol.
There is a CMOS battery left, the first thing to do is to remove it from the socket, for example, I had it glued, so you may have to make a little effort, but after that we disconnect it on the motherboard, again, so that we don’t have it in the future interfered.
Now, you should unscrew the three internal screws and one small one that holds the DVD drive. Then we hook the drive and pull it out of the case, as shown below.
Well, we complete this stage of disassembling the HP G62 by disconnecting the power cable from the board, gently prying it on both sides of the connector.
Step 2: Removing the Keyboard and Top Case Cover
At the second stage of disassembling the HP G62 laptop, turn it over and open it. Now we need to disconnect the keyboard, for this we take a mediator (as in the photo), any plastic card or a flat screwdriver and release the keyboard from the latches with which it is attached to the case, walking so completely around its entire perimeter.
If, after releasing it from the latches, you still cannot remove the keyboard early, then first turn the laptop over and check if all the screws have been unscrewed by you. Also, sometimes the manufacturer, in addition to latches, attaches the keyboard to the case using double-sided tape or glue. In this case, you can gently lift the keyboard and using, for example, a long screwdriver, gently tear it off the cover.
I want to note that when rubbing off the glue, you need to be extremely careful, so as not to accidentally damage the cable. In the photo below, I will show those areas where surfaces most often stick together.
After you release the keyboard, carefully turn it over and disconnect it from the motherboard by lifting the lock up and pulling the cable towards you.
The keyboard is removed, now we disconnect the remaining touchpad cables and other available contacts. Then unscrew three more screws on the cover itself.
Next, remove the cover, for this, again, take a mediator or a plastic card and pry off the cover, disconnect all the latches around the perimeter of the case, as shown below. In this case, I do not recommend using a screwdriver as you can damage the laptop case.
After removing the top cover, you will see the motherboard in front of you, on which you should disconnect the remaining cables and connectors, as well as unscrew a few more screws that hold the motherboard in the case. You can see what is where in the photo below.
This is where the second stage ends.
Stage 3: Cleaning the motherboard
So, freeing the mat. the board from any fasteners, we try to carefully disconnect it, while we look for the sound and VGA ports to also come out of the case.
In principle, we can say that this disassembly of the HP G62-b51SR laptop case is completed, it remains only to clean the case and the cooling system from dust. If everything is clear with the case, then to clean the cooling it will have to be removed from the board.
But, I want to note that after you remove the heatsink, you will have to replace the thermal paste on the processor, so if you don’t have one, I recommend that you first purchase it and only then clean the cooling system.
The radiator is held on by several screws, which also need to be unscrewed, but this should be done evenly on each side, so as not to damage anything. Usually there is a marking for cooling, showing in what order they should be unscrewed.
So, having disconnected the heatsink, using a cotton swab or a piece of cloth, we remove the remnants of the old, already probably dried up thermal paste from the processor. In total, you should get a completely clean and smooth surface.
Then, we repeat the same operation with cooling.
Having finished cleaning the thermal paste, you can proceed to disassemble, directly, the cooler, which, in principle, collects dust the most when working with the HP G62 laptop. So, to disassemble it, you need to open four small screws and disconnect the cooler from the radiator.
Well, then you will see everything for yourself, I think you know perfectly well what dust is and how to deal with it. The main thing is not to shove it under water, as a rule, it is recommended to clean the cooling system with various brushes and sharp, thin objects that can easily clean the radiator grille.
In general, after cleaning, we begin to assemble our HP G62, only we do everything in reverse order. I recommend that you pay attention to the fact that all cables are connected back and when tightening the case, do not confuse long screws with short screws, otherwise I'm sure that you can handle everything else.
We disassemble the laptop HP Pavilion dv6.

Hello friends! Today we will learn how to disassemble the HP Pavilion dv6 laptop, namely the dv6-6051er model.
First of all, we remove the battery and the compartment that covers the hard drive and RAM.
Next, unscrew all the bolts, as shown in the photo below (red), and also disconnect the hard drive and a small wi-fi board (orange).
Now disconnect DVD drive. Under it are 3 more bolts.
Under the hard drive there is a "mean" bolt, which is often overlooked. Be careful and unscrew it too.
Do not forget that the keyboard should not be strongly pulled up when removing, as you risk damaging the cable. Gently tilt it towards you and disconnect the cable.
The next step is to unscrew the bolts that are under the keyboard and disconnect the cables.
Now we hook something thin and hard on the top of the laptop and remove the panel.
Half the way has been completed and now there is little left for a full-fledged instruction " how to disassemble hp pavilion dv6 laptop".
Before us is an HP dv6-6051er laptop board. We understand further. We unscrew 1 bolt and disconnect the remaining loops.
Lift up the soundbar slightly so that the motherboard can be lifted.
The last thing that holds the board is the power wire. To remove it, you need to lift and turn the motherboard.
IMPORTANT! Do not pull on the wires, otherwise you risk the connector remaining in the connector, and the wires will be in your hands.
Use some tool (for example, a screwdriver) for auxiliary purposes.
Now the question is how to disassemble hp pavilion dv6 laptop" can be considered closed. The fee is in front of us.
However, if you need to clean the cooling system, then we disassemble further.
Now we clean the cooler from dust, the surface of the chips from the old thermal paste and apply a new one.

Why does the HP Pavilion G6-2323sr get very hot and noisy? Everything is simple! The problem of any laptop, yes, by the way, of any portable equipment, is small heat dissipation channels, which eventually become dirty and clogged with dust. Due to the limited space and lack of heat output (dust build-up) from the laptop, the temperature inside the equipment rises. As a result, it starts to get very hot. To prevent the system from overheating, which can damage the laptop components, the cooling fan begins to work hard to remove heat. Because of this, the noise level increases.
To eliminate such defects, mechanical cleaning of the cooling system is required. And the usual vacuuming of the radiator holes on the laptop case in the vast majority of cases does not bring a positive effect. Therefore, further on a specific example, we will consider how the HP Pavilion G6-2323sr is disassembled and then cleaned from dust. At the same time, we will replace the thermal paste to improve the thermal conductivity of the “bottleneck” of the processor-heatsink.
How to disassembleHPPavilionG6-2323sr
The first step is de-energization. Turn off the power supply and remove the battery.
Next, remove the keyboard. To do this, pry it off with a small flathead screwdriver. Next, we lead a screwdriver along the keyboard, unfastening the latches.
When all the latches are unfastened, turn the keyboard over and disconnect its cable from the motherboard.
We remove the keyboard to the side. We unscrew all the screws (there are 5 in total) that were hidden under the keyboard. And also turn off all the loops that we see.
We close the screen of the HP Pavilion G6-2323sr and turn the laptop over. There is a screw in the center of the case. Unscrew it first.
Further from the side where the battery was. There is an inscription "Release door" and an arrow indicating the direction. Slide the cover in this direction. If it doesn't work with your hands, you can pry a little with a flat screwdriver.
Underneath is the hard drive. RAM and a few loops. For convenience, everything should be disabled and removed.
Do not forget about the Wi-Fi module. We disconnect the wires from it (white and black) and unscrew the screw fixing it.
Under hard drive There is one more screw that needs to be removed.
And then unscrew all the screws on the laptop case in a circle. After that, we remove the drive for reading hard drives.
Now we need to separate the body. To do this, slip a flat screwdriver or a plastic card from any convenient side and unfasten the first latch
If all the screws are unscrewed and the cable is disconnected, then by unfastening all the latches in a circle, the case can be easily disassembled.
Before us motherboard. But there is no access to the cooling system, since it is located below. To remove the board, you must disconnect all cables and unscrew one screw.
After that, the board is very simply removed from the seats. Turning it over, you can see the cooling system in the form of a radiator and a fan.
In fact, this completes the disassembly of the HP Pavilion g6-2323sr. But we need to clean the cooling system. So, remove the radiator with a fan.
Next, disconnect the fan from the radiator by unscrewing the fixing screws.
After that, it should be something like this (maybe worse, maybe better)...
We remove the dirt and sweep away the dust with a brush.
If you need to replace the thermal paste on a laptop, then we clean the chips CPU and video processor.
And the pads on the radiator...
On the chips cleaned from the old thermal paste, we apply a layer of fresh.
And we collect everything in the reverse order. This completes the cleaning and replacement of thermal paste on the HP Pavilion g6-2323sr. At each step, do not forget to check all contacts and cables so that you do not have to re-disassemble the laptop later.
