We disassemble the HP Pavilion dv7 series laptop.

More precisely, in our case, disassembly is carried out using the example of the HP Pavilion dv7t-1000 model, but the instructions should be suitable for all models of the Pavilion dv7 line of laptops.

This guide will show you how to get to the memory modules and hard drives when upgrading a laptop, remove most internal components and clean the cooling fan.

Tools used

Before you begin disassembling, turn off the laptop and remove the battery.

Remove the 4 screws from the compartment cover hard drive and memory modules. Remove the cover.

Remove the 4 screws securing the hard drives (2 for each drive).

Slide hard drive 1 to the left until it releases from motherboard. Remove hard drive 1.

Slide HDD 2 to the right until it detaches from the motherboard. Remove hard drive 2.

Remove both RAM modules.

Disconnect the two antenna cables from the wireless network card. This laptop has three antenna cables, but only two are used.

One of the antenna cables is connected to the main pin on the wireless network card, and the second is connected to the auxiliary pin. All three antenna cables are marked.

Remove the two screws securing the wireless network card. Remove the wireless network card.

Unscrew the screw securing the CD/DVD drive.

Slide the CD/DVD drive to the left and disconnect it from the motherboard.

Remove the CD/DVD drive.

Remove all the screws from the bottom of the laptop, circled in the picture.

The green circle indicates the screw that secures the keyboard.

Don't forget to remove the two screws in the CD/DVD drive bay.

Start separating the panel above the keyboard (above the speakers) from the laptop body.

You can use a guitar pick to pry up the panel. Insert the guitar pick into the gap between the panel above the keyboard and the cabinet and slowly slide it along the edge of the cabinet.

Remove the panel above the keyboard. Be careful! The panel is still connected by a ribbon cable to motherboard.

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

The following picture shows the cable connector in the unlocked position.

Now you can remove the panel above the keyboard.

Remove the 4 screws securing the keyboard.

Lift the keyboard to get to the cable underneath.

Carefully unplug the keyboard cable connector.

Slide the brown clamp approximately 2 mm in the direction indicated by the arrows in the picture. There is no need to remove the brown clip from the base of the connector.

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

In general... here it broke) You disassemble thousands of keyboards, and nothing happens, but then one day - and the connector breaks!

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

Don't panic! A single pin retainer is still suitable for securing the connector.

Reach out antenna cables Wi-Fi through a hole in the case.

Remove the three screws securing the speaker module.

Disconnect the speaker cable from the motherboard (the green arrow in the picture points to it).

Remove the speaker module.

Disconnect the video cable from the connector on the motherboard.

Remove the 6 screws securing the monitor hinges (3 per hinge).

Start separating the monitor module from the laptop body.

In the next tutorial we'll look at .

By the way, to disassemble the display panel, it is not necessary to remove it from the case.

Disconnect and remove the non-volatile memory (CMOS)/system clock battery.

Remove all the screws from the bottom of the laptop, circled in the picture. The green circle marks a screw in the CD/DVD drive bay that is not visible.

Remove all screws securing the top of the case.

Disconnect the touchpad cable from the motherboard.

Start separating the top of the body from the bottom.

You can use a guitar pick in the same way as in step 6.

Remove the top housing.

This is what the top of the case looks like from the back:

Disconnect the USB board and audio card cables from the motherboard (indicated by 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 the motherboard from 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 serial part number. It is usually marked on a sticker in the memory module compartment. The HP serial part number is XXXXXX-001.

This is what the laptop case looks like without the 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 it is necessary more often, but as my practice shows, once a year is quite enough, unless of course you like to lie with your laptop on a duvet or something where there is a lot of dust.
It takes about 1.5 hours to disassemble, clean and assemble slowly if you are not in a hurry. True, I must say that there is no need to rush in such matters, as they say, hurry is needed when catching fleas
To begin with, we note that for those who have never disassembled such devices and are afraid of messing up, it is better to entrust this matter to someone who knows how to do it, and for those who are full of determination, read the material further.
I’ll note right away that if you often forget something, it’s 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 where you unscrewed them and put the bolts on it), and you yourself won’t get confused and will waste less time .
Well, that’s it, but no, I forgot to mention that for this process you will need a thin Phillips and flathead screwdriver, thermal paste (to suit 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 reminding that we do everything carefully and leisurely
Well, let's start the mini guide
Photo of the device itself:

Next, remove the RAM by releasing the clamps (shown in blue) and take out the strips themselves. Then we remove the WiFi module by unscrewing the bolts (marked in red) and removing 2 terminals and removing the module itself. We remove the drive by unscrewing the bolt, and you can pry it up and pull it out (shown in yellow). We remove the hard drive (if you have 2 of them, then remove both) by unscrewing the bolts and disconnecting the cable (shown in green). We also remove the BIOS battery (marked in purple), I personally don’t remove it, but I advise you because If you don’t notice, you can break 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 color), a short cross bolt (red color), and a generally short one (green color), and we also remove 2 connectors (purple color) . We unscrew all these bolts.

Next, we remove the keyboard, unscrew this bolt (red) and turn it over and pry the keyboard up along the top edge with something thin, you can use the same knife and take it out, just don’t rush to pull it out because... it is connected by a short cable. They simply lifted and disconnected the cable itself. By the way, don’t even try to just pull the cable because... you will tear it, first open the lock (this is such a small plate, I will show it to you along the way):

Next, we disconnect the cables shown in blue (by the way, the blue arrow shows the lock itself, the white bar that needs to be lifted on one side and the cable itself can be easily pulled out), and also unscrew the 2 bolts shown in red.

Now carefully pry the lid off with a flat and thin object, I used a knife for this, but it’s worth considering that you can’t push it in there more than half a centimeter, otherwise you risk cutting something with it.

Not long ago, they brought me an HP ENVY dv7 laptop for repair - almost new, still in protective films a device whose screen was a pitiful sight. I did not ask the owner what caused the damage to the computer, but 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, was alive and functioning well. operating system successfully loaded.

All that remained was to disassemble the laptop, find out the model of the matrix installed in it and replace it with a new one. I started working by searching the Internet for instructions on how to disassemble a laptop. To my surprise, I found only one link where the photographs showed the disassembly of this model. I was not too lazy to print out the photos from the website so that I could later label them with the sizes of the screws removed from the laptop case.

Knowing from the experience of previous repairs, there will be quite a few of these screws of different lengths. I prepared several jars for storage in advance, marking them according to the size of the screws.

And so, let's start disassembling. Turning the laptop upside down, first disconnect the battery. Next, unscrew the only screw and remove the cover under which the memory, hard drive, and WI-FI module are hidden. We carefully unscrew and disconnect all this equipment. From the Wi-Fi module, first disconnect the antenna connectors. Right there, under the cover, the BIOS battery is glued - disconnect its connector and carefully pry it off with a screwdriver and separate it from the case.

We begin to unscrew the screws circled in the photo above. We put them in pre-prepared jars, sorting them by size. We take out the DVD-ROM, under which two more screws are found. We unscrew them. Turn the laptop over to its working position. Now you have to remove the keyboard. We pry the latches at the top of the keyboard with a thin (preferably plastic) object, lifting the keyboard where the latches are released and placing something under it (for example, matches) so that the keyboard does not return to its place. After all the latches are released, carefully lift it and disconnect the cable. 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 by numerous latches. We proceed by analogy with the keyboard. The frame has been successfully dismantled - we see the inside of the laptop.

Now our task is to disconnect the cover of the device with the matrix installed in it. Carefully release the wires from the housing Wi-Fi antennas, a long cable from the speakers located in the lid, and peel off the matrix cable from the radiator. Unscrew the four screws that secure the metal cover.

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

All that remains is to remove the broken matrix from the laptop lid. The frame around it is also held in place by numerous latches along the entire perimeter. The only subtlety in disassembly is two screws that are hidden under the speaker grille. It must be carefully peeled off on both sides until the screws appear. We unscrew them.

After this, the screen frame 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 cable from the web camera board at the top of the cover.

Screw dimensions (diameter x length):

Under battery– 2.5 x 2.5

For DVD-ROM – 2.5 x 2.5

HDD mount – 2.5 x 4.5

Wi-Fi module mounting – 2.5 x 2.5

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

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