About this board

This thread is for the Lenovo ThinkPad L13 Gen 2 EC with main board 19837-1.

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 listed for this board
  • BIOS (full SPI chip dump, .bin)
  • EC / KBC firmware, if the board uses a separate EC chip
  • 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.

Before flashing, always read and save the original chip. It holds the serial number, UUID, MAC address and ME data for that exact machine.

Can you help me repair the original BIOS? It powers on but doesn't display video. Other files were tried, but the computer still won't turn on with them.
