Tested BIOS dump for the TrekStor Surfbook A13 laptop on mainboard INET-P313J revision 1.2, stored as a 4.34 MB RAR. The name marks it as tested OK, meaning it was confirmed to boot on a working unit. Use it to reprogram the SPI flash chip with a programmer when the notebook shows no display or hangs at power-on after a failed update. Compare the revision silkscreened on the PCB with 1.2 before flashing, save the original contents first, and make sure the image size equals the chip capacity.
