HP 15 laptop BIOS for the Compal LA-C811P mainboard, with the token ABQ52 identifying the Compal project code that appears alongside the board number. The 3.32 MB RAR should be unpacked and the image written to the SPI flash with an external programmer during no-POST repairs. Check that the LA number and revision printed on the PCB agree, verify the chip capacity matches the file, and always save a dump of the original firmware first so model and serial data can be restored.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.

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 →
