About this board
Files for the Lifebook AH90/B1 AH77/B1 WA3/B1 AH53/B2 WA2/B2 AH50/B3 AH47/A3 motherboard, board number 6050A2876401.
The board was manufactured by Inventec for Fujitsu. Inventec board numbers start with 6050A, so you can confirm it on the PCB silkscreen. This listing is for revision 1.2; another revision of the same board can need a different file.
Files usually needed for this board
- BIOS (full SPI chip dump, .bin)
- EC / KBC firmware, if the board uses a separate EC chip
- Schematic (PDF)
- Boardview (.brd / .bdv / .cad)
Typical reasons to reflash: no power or no display after a failed BIOS update, a BIOS/supervisor password lock, or a corrupted Intel ME region.
Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.
