Firmware dump for the HP 15-bw015ur notebook on Compal board LA-E831P, supplied as a 4.27 MB RAR archive. The LA-prefixed number with a P suffix is standard Compal motherboard naming. Technicians use such images to rewrite the BIOS chip with an SPI programmer when a laptop shows no display, loops on boot or lost firmware after a failed update. The name does not say whether ME was cleaned or EC is included, so inspect the contents, back up the original chip, and verify the board number and flash size before writing.

How to open a .rar 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 →
