Schematics in PDF for the ASUS K75DE laptop on Compal board LA-8371P, revision 0.2. Compal uses LA-xxxxP numbers, and ASUS sourced this design from that ODM. The diagrams show the charger, system power rails, sequencing signals and connector pinouts, letting a technician trace a missing voltage or check component values. Open it in any PDF reader and search net names to move between pages. Revision 0.2 is an early version, so compare it with the revision printed on your PCB.
