Lenovo T440 shuts off after 20-25 seconds

T440 shuts off in:

  • Windows
  • BIOS
  • PXE

This happens if the AC Adapter (tried multiple) is plugged in, not plugged in. I've also un plugged the internal battery, same problem happens. I've tried new RAM, resetting CMOS connection, no SSD. It always shuts off. I've noticed that the CPU fan comes on right at power up but shuts down after and am not sure if this is normal or not. 


Any ideas?

It might be that your fan is faulty if it shuts down because of overheating.
