About this board
This thread is for the ThinkPad P1 Gen 3 (Types 20TH 20TJ) X1 Extreme Gen 3 (Types 20TK 20TL)… with main board 19770-1.
The board was manufactured by Wistron for Lenovo. Wistron board numbers are 5–6 digits plus a revision, so you can confirm it on the PCB silkscreen.
What this thread covers
- BIOS (full SPI chip dump, .bin)
- 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 19770-1 in File Finder.
