About this board
This thread is for the W840SU W840SU-T 6-71 W8400-d03.
Compare the board number printed on the PCB (near the RAM slots or under the battery) with the files before you flash. Board revision: 3.8. Match the revision as well as the board number.
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.
Before flashing, always read and save the original chip. It holds the serial number, UUID, MAC address and ME data for that exact machine.
