BIOS package for the Lenovo G50-70 laptop in its Intel Core i5 CPU configuration, packed as a 3.21 MB RAR archive. The name references ACLU1 and ACLU2, the board identifiers used for this platform, suggesting the dump suits either variant. Technicians use such images to recover a bricked or password-locked machine by writing the SPI flash directly with a programmer like the CH341A. Confirm the board marking on your PCB matches, check that the image size equals the flash chip capacity, and back up the existing chip contents before flashing.

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 →
