In this guide I explain how to disassemble an HP Pavilion dv7 notebook.
This is my first disassembly guide for HP pavilion dv7 series.
To be precise, I’m taking apart an HP Pavilion dv7t-1000 model.
I found that HP Pavilion dv7 notebooks come in different body types. If your computer doesn’t look like one shown in this guide, check out:

Before you start, turn off the computer and remove the battery.

Remove the CD/DVD drive.
Remove all marked screws from the bottom case.

Start separating the speaker cover from the top cover.
You can use a guitar pick as a case cracker. Insert the guitar pick between the speaker cover and case and slowly move along the side.
Lift up the speaker cover. Be careful, it’s still connected to the motherboard.
In order to remove the cable, you’ll have to unlock the connector first.
Move the brown clip about 2 millimeters in the direction shown by two arrows. The clip must stay attached to the connector base.
On the picture below the connector is shown in the unlocked position.
Now you can remove the speaker cover.
Remove four screw securing the keyboard.
Lift up the keyboard from the base and access the cable connector underneath.
Carefully unlock the keyboard cable connector.
Move the brown clip about 2 millimeters in the direction shown by two arrows. The brown clip must stay attached to the connector base.
If you damage the connector, the keyboard will not work.
Well… I broke the connector.
As you see, the left pin on the brown clip is missing.
It’s still possible to use this clip to lock the connector.
Pull Wi-Fi antenna cables though the opening in the cover.
Remove three screws securing the speaker assembly.
Disconnect the speaker cable (green arrow) from the motherboard.
Remove the speaker assembly.
Disconnect the video cable from the connector on the motherboard.

Lift up the right side of the motherboard as it shown on the picture below and disconnect the DC-IN jack cable.
Remove the motherboard from the notebook base.
On the opposite side of the motherboard you can access the processor (CPU) when the heat sink is removed.
By the way, the best way to find a replacement motherboard is searching by the HP part number. The part number should be located on a sticker in the memory compartment. The HP part number looks like XXXXXX-001.
Here’s the bottom case without motherboard installed.
The USB board, audio board, cooling fan and DC-IN jack are mounted on the base.
The DC jack attached to a harness.
In order to remove the cooling fan, simply remove two screws securing the fan.
As you see, the cooling fan is dusty and has to be cleaned.
There are only two fans listed in the service manual for HP Pavilion dv7 series. They are listed on the page 27.
