In today's article, disassembling an HP Dv7 laptop: remove the battery, remove the hard drive and RAM, remove the Wi Fi module, pull out the keyboard, and get to the cooling system. For disassembly, we need: a screwdriver, tweezers, a plastic card, a dust brush, thermal paste (if there are plans to replace it).

You can see the disassembly instructions in pictures or at the end of the article:

1. Latch to the side (along the red arrow) - pull out the battery along the green arrow

2. The lid hides the RAM and the hard disk from us, it is held by six bolts, we unscrew all the bolts indicated by the red arrows and remove it.

3. To remove the drive- you need to unscrew the bolt near the number one and pull it. To pull out the hard drive- we unscrew the two bolts indicated by the red arrows, and pull it out in the direction of the green arrow. To pull out ram- push the latches to the sides along the green arrow

Begin to separate the panel above the keyboard (above the speakers) from the laptop chassis.

You can use a guitar pick to pry off the panel. Insert your guitar pick into the slot between the panel above the keyboard and the body, and slide it slowly along the edge of the body.

Remove the panel above the keyboard. Be careful! The panel is still daisy-chained to the motherboard.

To disconnect a ribbon cable, you must first unplug the connector.

The following picture shows the ribbon cable connector in the detached position.

Now you can remove the panel above the keyboard.

Remove the 4 screws securing the keyboard.

Lift the keyboard up to reach the ribbon cable underneath.

Carefully unplug the keyboard cable connector.

Slide the brown tab about 2mm in the direction indicated by the arrows in the picture. You do not need to detach the brown retainer from the connector base.

Do not break the connector, otherwise the keyboard will not work after assembly!

In general ... here it broke) Thousands of keyboards are disassembled, and nothing, and then once - and the connector is broken!

So, as you can see, in the picture, the latch is missing a pin on the left.

Don't panic! The one-pin latch is still useful for securing the connector.

Route the Wi-Fi antenna cables through the hole in the case.

Remove the three screws securing the speaker module.

Disconnect the speaker cable from the motherboard (indicated by the green arrow in the picture).

Remove the speaker module.

Disconnect the video cable from the connector on the motherboard.

This is how the upper part of the case looks from the back side:

Disconnect the USB and audio board cables from the motherboard (indicated by the green arrows in the picture).

Disconnect the cooling fan cable from the motherboard (indicated by the yellow arrow).

Remove the 4 screws securing the motherboard.

Lift up the motherboard on the right side as shown in the picture below and disconnect the power supply connector cable.

Remove the motherboard from the laptop base.

On the back of the motherboard is the processor. To get to the processor, you must first remove the heatsink.

The easiest way to find a replacement motherboard on sale is by the part number. It is usually identified on a sticker in the memory module compartment. The HP serial number is XXXXXX-001.

This is what a laptop case looks like without a motherboard:

The USB board, audio card, cooling fan, and power supply connector are attached to the base of the laptop case. The power supply connector is attached to the wires.

To remove the cooling fan, you need to remove the two screws that secure it.

As you can see, the fan is dusty and needs to be cleaned.

Disassembly is complete. Reassemble in reverse order.

Well, let's start with the fact that I have owned this device for 4 years now, I clean it about once a year, you can say that you need to more often, but as my practice shows, once a year is quite enough, unless of course you like to lie with a laptop on a duvet or there where there is a lot of dust.
On the spot, cleaning and assembling slowly takes about 1.5 hours if you are not in a hurry. True, I must say that you should not rush in such matters, as they say, rush is needed when catching fleas
To begin with, we note that those who have never disassembled such devices and are afraid to screw it up, it is better to entrust this matter to someone who knows how to do it, and those who are decisive read the material further.
I note right away if you often forget something, then it is better during the disassembly process to mark where you unscrewed / removed this or that part (for example, when you unscrew the bolts, write on a piece of paper from where you unscrewed them and put the bolts on it), and you yourself will not get confused and spend less time ...
Well, everything seems to be, but I forgot to mention that for this process you need a thin Phillips and flat screwdriver, thermal paste (for your taste, I used AlSil 3 for lack of anything else) and a knife, and why I’ll show and tell you further. Well, I think it's worth recalling that we do everything carefully and slowly.
Well, let's start a mini guide
Photo of the device itself:

As you can see, it is far from clean.
And now we start the process, first we remove the battery by pulling the highlighted lever to the left, take out the battery and pull the same lever to the right and remove the compartment cover.

Next, we remove the RAM by releasing the clamps (shown in blue), we take out the strips themselves. Then we remove the WiFi module by unscrewing the bolts (marked in red) and removing 2 terminals, we remove the module itself. We remove the drive by unscrewing the bolt, and you can pry it out and pull it out (shown in yellow). We remove the hard drive (if you have 2, then remove both) by unscrewing the bolts and disconnecting the cable (shown in green). And we also dismantle the bios battery (marked in purple), personally I do not take it off, but I advise you. if you don’t notice, you can cut off the already thin wires.

Our laptop will look like this. Now we will unscrew the top cover, looking ahead I will say that 3 types of bolts are used here: a long cross bolt (blue), a short cross bolt (red), and generally a short (green), and also remove 2 connectors (purple) ... We unscrew all these bolts.

Next, remove the keyboard, unscrew this bolt (red) in the same place and, turning it over, pry the keyboard along the upper edge, with something thin, you can use the same knife and take it out, just do not rush to pull it because it is connected with a short loop. They just lifted and disconnected the loop itself. By the way, do not try to just pull the train. you will tear it, first open the lock (this is such a small slab, along the way I will show it to you):

Next, turn off the loops shown in blue (by the way, the lock itself is shown with a blue arrow, the white bar which must be lifted on one side and it is easy to pull out the loop itself), and also unscrew the 2 bolts shown in red.

Now we carefully pry the lid with a flat and thin object, I used a knife for this, but it should be borne in mind that you cannot drive it there by more than half a centimeter, otherwise you risk cutting something with it.

Not so long ago, they brought me an HP ENVY dv7 laptop for repair - a practically new device, still in protective films, the screen of which was a pitiful sight. I did not ask the owner what caused such an injury to the computer, but I promised to repair the laptop.

First of all, I connected an external monitor to the laptop and made sure that the filling, unlike the matrix, is alive and functioning well. The operating system has booted successfully.

It remained to disassemble the laptop, find out the model of the matrix installed in it and replace it with a new one. I started by searching the Internet for a laptop disassembly procedure. To my surprise, I found only one link, where the disassembly of this model was shown in the photos. I was not too lazy to print photos from the site in order to subsequently sign on them the dimensions of the screws unscrewed from the laptop case.

Knowing from the experience of previous repairs, these screws of various lengths will not be enough. I prepared several jars for storage in advance, marking them for the size of the screws.

And so, let's start disassembling. Having turned the laptop upside down, first of all, we disconnect the battery. Then, unscrewing the only screw, remove the cover, under which the memory, hard drive, and WI-FI module are hidden. We carefully unscrew and disconnect all this economy. From the Wi-Fi module, first disconnect the antenna connectors. Immediately, under the lid, a BIOS battery is glued - we disconnect its connector and carefully, prying it off with a screwdriver, separate it from the case.

We proceed to unscrewing the screws circled in the photo above in circles. We put them in pre-prepared jars, sorting by size. We take out the DVD-ROM, under which two more screws are found. We unscrew them. We turn the laptop over to the working position. Now you have to remove the keyboard. We pry the latches on the top of the keyboard with a thin (preferably plastic) object, lifting the keyboard where the latches were released and placing something under it (for example, matches) so that the keyboard does not come back into place. After all the latches are released, carefully lift it up and disconnect the ribbon. Disconnect all cables located under the keyboard. Including the matrix cable.

Then we carefully pick up the black frame of the case, which is held along the entire perimeter with numerous latches. We act by analogy with the keyboard. The bezel has been successfully dismantled - in front of us is the filling of the laptop.

Now our task is to detach the cover of the device with the matrix installed in it. Gently release the wires of the Wi-Fi antennas from the body, a long cable from the speakers located in the lid, and peel off the matrix cable from the radiator. We unscrew the four screws of the metal fastening of the cover.

That's it, the lid is in our hands. We put the laptop aside, it will not be needed until the assembly begins.

All that remains is to remove the broken matrix from the laptop lid. The framing around it also keeps on numerous latches along the entire perimeter. The only subtlety about the disassembly is the two screws that hide under the speaker grill. It must be carefully peeled off on both sides until the screws appear. We unscrew them.

After that, the screen bezel can be easily removed. We take out the matrix by unscrewing several screws, it is impossible to confuse anything there. Raise the matrix a little and disconnect the ribbon cable from the web camera board at the top of the cover.

Screw dimensions (diameter x length):

Under the battery - 2.5 x 2.5

For DVD-ROM - 2.5 x 2.5

HDD mount - 2.5 x 4.5

Mount the Wi-Fi module - 2.5 x 2.5

Circled in the photo around the perimeter of the case - 2.5 x 8.5

Perhaps this description will help someone save a few hard-earned rubles by avoiding going to the service(and, consequently, payment for the work performed in it) if it is necessary to replace the matrix in a laptop, which now is not difficult to acquire on your own.
