EC and BIOS firmware set in a RAR archive for the Compal LA-7912P motherboard, revision 1.0, with Q5WVL as the project code. Compal uses the LA-xxxxP numbering for its board designs, which appear in laptops sold under several brands. Having both the embedded controller firmware and system BIOS helps when a board does not power on or charge correctly. Match the LA number and revision on the PCB, back up both chips, and confirm each image size matches its flash chip.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
