T440S wont start, no lights, power supply connectors are good. battery reset does not resolve

2020-11-27, 12:05 PM

checked power supply & connectors nothing broken or deformed.

tried the 10 / 30 sec reset, not fix

tried internal battery & coin BIOS battery + 30 sec reset & 30 sec power

tried above with ten power button pushes

 

I noticed a micro switch near the reset button. Is that a kill switch?

Is there a battery recall? or sensor issues with this series?

What else should I try?
