Schematic for Compal LA-7452P, project PLW00, in PDF form inside a RAR archive, with the name pointing to a UMA version, which means integrated graphics only. The 0728 token is probably a date code. Use it to trace power rails, the EC and power-on sequence and signal paths when diagnosing shorts or missing voltages. Any PDF reader opens it. Discrete-GPU builds may differ, so check the board variant and revision first.
