Second copy of an 8 MB BIOS dump labelled HP 15 GQ64 fanless, where GQ64 may be a chip marking and fanless points to the passively cooled variant, though neither is explained. No board number or revision appears. The image fits a 64 Mbit SPI flash and is written with an external programmer to recover a laptop that fails to start. Compare it with the first copy, verify the board markings and chip capacity, and back up the original chip before flashing.
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 @biosfilebins. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
