Production-revision R1.0 schematic set for the Compal LA-6921P laptop motherboard, stored in a 2.00 MB RAR archive. Compal is an ODM, and its LA codes are printed on the board itself, which is the safest way to confirm you have the right drawings whatever brand is on the lid. Open the PDF after extracting and use it to follow rails, check the power-on sequence, look up part values and find where a signal goes between chips. Match the revision on your PCB to R1.0 before replacing components based on these sheets.
