About this board

This thread is for the Lenovo ThinkPad L390 LKL with main board 18724-1M.

Lenovo had this board built by Wistron; Wistron board numbers are 5–6 digits plus a revision. Check the number printed on the PCB before you download.

What this thread covers
  • BIOS (full SPI chip dump, .bin)
  • Schematic (PDF)

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 18724-1M in File Finder.
