Service material for an HP laptop on Compal board LA-C701P, project codes AHL50 and ABL52, in a 2.77 MB RAR. Compal marks its boards with LA- numbers and five-character project codes, and one design often covers several models. The archive likely holds a schematic or boardview for tracing power rails and locating components, but check after unpacking. Match the LA number and revision on your PCB with the documents before relying on measured values or test points.
