This is a 3rd laptop I got for repairs in our Hackerspace, it's apparently caused by Windows Update which tried to flash the BIOS chip and fails during the operation resulting in corrupted/malfunctioning data on the NAND chip used by the firmware for system initialization.
Lenovo apparently foresaw this issue happening and put 2 footprints on the PCB for 2 NAND chips, but only populated one.. cheap fucks! If they populated both this issue could have been prevented..
