ASUS K75V circuit diagram prepared by Compal for the LA-8222P mainboard, revision 1.0, supplied as a PDF of about 1.87 MB. Compal identifies its laptop boards with LA numbers ending in P, and ASUS sourced this platform from that ODM. Use the pages to follow the charger and system power stages, check component values around a short and locate the nets behind a no-power or no-display fault. Always compare the board number and revision printed on the PCB with the schematic before measuring against it.
