Lenovo G50-30 firmware archive marked Compal with the ACLU9 and ACLU0 codes, which are the board design names for this family. No board number or chip size appears in the name, so open the archive to see whether it holds a BIOS image, EC firmware or both. A dump like this is written to the SPI flash with a hardware programmer to revive a board after a bad update or corruption. Read and save the existing chip first, then compare the image size with the flash capacity before programming.

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 →
