cannot turn on Thinkpad L540 when display cover was closed - need to replug main battery

My nice L540 20AV recently began having this issue which is surely a hardware issue but I do not know which part could be the issue.


Most of the times when I close the cover after powering the machine off or when sent to standby, I could not turn it on. Stand-alone or in the docking station. Nothing happens when pushing the power button.

When I unplug and replug the main battery, the machine can turned on immediately.


This is not a battery issue as this happens with all batteries that I have.


I tried several BIOS versions, but this did not change the behaviour.


As the machine has an i7 MQ and other high end components so I would like to use it some longer.

Of course it is out of warranty.


Anyone knows what replaceable part could cause this issue?
