Questions about this item

How do I verify the 638856-001 motherboard posts correctly after installing the Xeon E5 CPU?

Power on the system and confirm the BIOS screen appears with the correct CPU identification; listen for a single beep code indicating a successful POST.

What components come with the 638856-001 mainboard and what must I source separately for a G4-1000 or G7-1173dx repair?

The listing supplies the bare motherboard only; you must reuse or purchase the Xeon E5 processor, memory modules, heatsink, and any model-specific cables or brackets separately.

Which 638856-001 version matches my HP laptop — the DA0R22MB6D0 or DA0R22MB6D1 board for G4-1051xx and G7-1167dx models?

Check the sticker on your original board; DA0R22MB6D0 and DA0R22MB6D1 are different revisions, so order the exact part number printed on the failed unit.
