Firmware labelled QT6A-MB-C, apparently a Quanta QT6 project board at revision C, though the name gives no laptop model. The 107 KB archive is too small for a main BIOS and more likely contains an embedded controller image. Technicians use EC dumps to fix power-on, charging or keyboard faults caused by corrupted controller firmware. Check the board marking and revision on the PCB, read the original chip before writing, and make sure you are flashing the correct device rather than the main SPI BIOS.

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 →
