About this board

This thread is for the Lenovo ThinkCentre M70a with main board 19435-1.

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.

Files usually needed for this board
  • BIOS (full SPI chip dump, .bin)
  • Schematic (PDF)
  • Boardview (.brd / .bdv / .cad)

Usually needed when the PC turns on but never reaches POST, loops on start-up, or lost its BIOS during an update.

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 19435-1 in File Finder.
