Compal LA-B301P motherboard schematic, revision 1.0, supplied as a 1.58 MB compressed RAR. The name gives only the ODM board code and revision, with no laptop brand or chipset. Compal, the board maker, uses LA- numbers across many OEM laptop lines. Technicians rely on these diagrams to measure standby and main rails, follow the power-on sequence, diagnose a short to ground and identify components near the charger or CPU regulator. Check the board number and revision on the PCB before relying on part values.
