Fujitsu LIFEBOOK U772 EC 25Q80

BIOS .bin 1.00 MB Shared

Embedded controller firmware for the Fujitsu LIFEBOOK U772, a raw 1.00 MB binary read from a 25Q80 chip, an 8 Mbit SPI flash. The EC handles power sequencing, charging, keyboard and fan control, so a corrupt EC image can stop the laptop powering on at all. Program it into the separate EC flash, not the main BIOS chip, using an SPI programmer. A matching BIOS dump from a 25Q64 is listed separately. Check that your chip marking matches and back up the existing contents first.
