BIOS and EC firmware pair for the Lenovo ThinkPad 13 on Quanta motherboard DA0PS9MB8E0 revision E, in a 5.17 MB RAR archive. Quanta numbers start with DA and finish with a revision letter, both printed on the PCB, so check that the board reads revision E. The EC image helps when power, charging or keyboard faults stem from controller firmware rather than the main BIOS. Back up both original chips with a programmer and verify each image matches its chip capacity before writing.
