In this guide I show how to disassemble a HP Pavilion dv2 laptop. 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 laptop is turned off before you start taking it apart.

Loosen five screws securing covers on the bottom of the laptop. Lift up and remove all covers.
Under these covers you can access the hard drive, memory module, wireless card.
NOTE: HP Pavilion dv2 laptop 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 laptop.
