Compal LA-8864P schematic at revision 0.3, supplied as a 1.37 MB PDF; the name also carries the project code B21CE. LA-xxxxP is the board numbering Compal uses for the laptops it builds for several brands. Use it to trace power rails, follow the power-on sequence, find the PWM controllers and check where a short sits before you replace parts. Any PDF reader opens it. Revision 0.3 is an early drawing, so compare it with the board number and revision printed on your PCB before trusting individual component values.
