About this board

This thread is for the L480 (type 20LS 20LT) (ThinkPad) EL480/EL580 with main board NM-B461.

The board was manufactured by LCFC for Lenovo. LCFC (Lenovo/Compal) board numbers start with NM-, so you can confirm it on the PCB silkscreen.

Files listed for this board
  • BIOS (full SPI chip dump, .bin)

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.
