Compal LA-A091P laptop motherboard schematic, revision 1.0, in a compact 1.26 MB PDF. The LA-xxxxP pattern is Compal's board numbering, used on notebooks built for many brands, so the laptop model is not named here. Use the diagrams to trace power rails from the charger and PWM controllers, follow the power-on sequence, and check signals around a short. Make sure the LA-A091P code and revision printed on the PCB match before relying on values, since other revisions may differ.
