Schematics for the Compal LA-2891 notebook mainboard, revision R0.1, compressed into a 933 KB RAR file. The name omits the usual P suffix, but the number follows Compal's LA-series board coding, which appears on laptops sold under various brands. Extracted, the diagrams help trace the power path from the adapter jack to the CPU regulators, locate test points and narrow down a short on a rail. R0.1 is a very early revision, so compare the code and revision on your PCB carefully, as later boards may differ.
