Hi I suggest you go to the HP site at the link below and select your particular version and then seek out the manual for it.
But system boards are very expensive and tricky to replace. if you are not experienced in laptop repairs then forget it. It's really not worth the effort of replacing the system board unless you can get a good used one.
Just buy another laptop and get your data transferred. Go for a used Dell D610. Excellent machines, about 4 years old now but I sell loads and NEVER had a problem. Good build quality, unlike most of todays laptops
