BIOS and EC firmware for a laptop board labelled GPC52 with Compal number LA-J641P, revision 1.0, dated 2020-03-26; no brand is given in the name. LA-xxxxP is the Compal ODM numbering, so the board may appear in machines from several brands. Both the main SPI BIOS and the embedded controller firmware can be reflashed with a programmer to restore power-on or charging behaviour. Back up the original chips, match the revision on the PCB, and confirm each image fits its chip size.
