About this board
Dell Latitude XT PP12S-C U7700 — motherboard 48.4S701.011.
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.
