About this board
ThinkPad 10 Type 20E3 20E4 Type 20E3 — motherboard LA-B631P.
The board was manufactured by Compal for Lenovo. Compal board numbers start with LA- and end in P, so you can confirm it on the PCB silkscreen. This listing is for revision 1.0; 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.
