How do I replace the fan in my Presario V6000?

Liz, here is the way HP suggests you go about it

"1. Prepare the computer for disassembly and remove the following components:

❏ Hard drive

❏ Memory module compartment cover

❏ Optical drive

❏ Switch cover

❏ Keyboard

❏ Display assembly

❏ Top cover

❏ System board

2. Turn the system board upside down with the expansion port 3

and external monitor port toward you

3. Disconnect the fan cable 1 from the system board.

4. Remove the four Phillips PM2.5×5.0 screws 2 that secure the fan/heat sink assembly to the system board.

5. Remove the fan/heat sink assembly 3."

To definitely getting this task accomplished, download the service manual from here. It will show you exactly how to do it. Hope this helps, good luck.
