Looking for a laptop motherboard

My laptop is having some problems with its power supply and since that's linked directly to the motherboard I am probably going to have to replace that. I hate taking minutes by hand (or rather, typing them out after the fact).

We're looking for parts (a motherboard) for an HP compaq laptop. Does anybody have either a part number 456609-001 or 456608-001 lying around that they can miss, or know where I can get one cheaply?

Much appreciated, thanks! =)
