Although replacing parts on laptop computers, such as the Compaq Presario V6000, is not as easy as replacing parts on a desktop, it's certainly not impossible. If your V6000's motherboard fails, you can purchase a replacement motherboard and install it in the computer. Doing so requires you to perform a near total tear-down of the computer, but with a little patience you can perform this repair and breathe new life into your V6000.
