Second copy of the HP Compaq 6531s schematic for the Inventec ZZI MV board at revision A03, this one at 854 KB, so its contents or page set may differ slightly from the smaller file. Confirm the project name and revision printed on the PCB before relying on it. The drawings let you follow the power-on sequence, measure voltages on the main and standby rails, and identify parts around a shorted capacitor or MOSFET. It opens in a normal PDF viewer. Searching for net labels is the fastest way to trace a signal across sheets.
