Description
BIOS dump for the Lenovo G505S laptop, board LA-A091P, PCB revision 1.0, from the Compal design. The archive is a RAR of about 2.4 MB and includes EC/KBC firmware alongside the BIOS image. Technicians use a dump like this to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update, and the EC/KBC firmware can be relevant when the embedded controller needs restoring too. Confirm that the board number and revision match your board before flashing, and back up the original chip contents first.

Questions about this file
How do I flash this BIOS dump?
Write it to the SPI flash chip with a programmer such as the CH341A and a SOIC8 clip. Read and keep the original contents first, and check that the chip size matches the dump.
Will this BIOS work on my board?
Only if the board number and revision match: Lenovo G505S LA-A091P. Dumps from a different board or revision can leave the board dead.
What does “clean ME” mean?
The Intel ME region in the dump has been reset, so it can be used on another board of the same model. Keep your original dump and transfer serial numbers if needed.
