In this guide I show how to disassemble a HP Pavilion dv2 model. I’m taking it apart in order to replace the motherboard.
HP Pavilion dv2 motherboard comes with the processor attached to it and the motherboard is not very expensive. If the motherboard failed it might make sense to repair the laptop.
Make sure the computer is turned off before you start taking it apart.
Remove the battery.
Loosen five screws securing covers on the bottom. Lift up and remove all covers.
Under these covers you can access the hard drive, memory module, wireless card.
NOTE: HP Pavilion dv2 has only ONE memory slot.
It’s not necessary to remove the memory module and wireless card for the purpose of my guide. I’ll leave them connected to the motherboard.
Remove four screws securing the hard drive mounting bracket.
Slide the hard drive assembly to the left to disconnect it from the connector on the motherboard.
Lift up and remove the hard drive assembly.
If you are replacing the hard drive you’ll have to transfer the mounting bracket to the new drive.
You can use any 2.5″ SATA hard drive.
Remove two screws from the bottom. These screws securing the keyboard.
Lift up the upper side of the keyboard and move it towards the screen.
Here’s where to find the keyboard cable connector.
It’s necessary to unlock the connector and release the cable before removing the keyboard.
In order to unlock the connector you’ll have to lift up the left side of the locking tab with your fingernail.
The locking tab will open up at a 90 degree angle.
It must remain connected to the brown connector base.
On the following picture the same connector shown in the unlocked position.
Now you can pull the cable from the connector.
