T420 Windows 7 Fails to power up without mains power supply

2017-09-06, 9:48 AM

Hi,

I have tried two batteries.

Checking the Battery  Icon on Thinkpad it  reports 88% Charging

Sometimes it fails to boot up then I have to remove battery and press power button while applying the mains adaptor.

Any suggestions

Thank You
