About this board

Files for the Dell Inspiron 17 7746 motherboard, board number 14202-1.

The board was manufactured by Wistron for Dell. Wistron board numbers are 5–6 digits plus a revision, 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)

Usually needed when the laptop powers on with a black screen after a BIOS update, is stuck in a boot loop, or is locked with a BIOS password.

Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.

If you have a working file for this board, please share it below. More files: search 14202-1 in File Finder.
