I got a refurbished DELL XPS 13 9370 in March 2019 and recently it has just started to randomly just turn itself off after 2-5 minutes of booting into windows.
To get it to power up again I need to turn it on/off several times.
I have checked the battery in the BIOS, it looks good and still takes a charge.
I have noticed it only happens when connected to my docking station / plugged in. No restarts when just running off battery.
I can't upgrade the BIOS as that requires it to be plugged in.
I have another plug I will test at work.
I've turned off the windows, auto-restart on system failures, as i read that around these forums.
I get an invalid-time bios error occasionally also after the random shutdown, researching that points to either CMOS battery or moboboard charging circuit
What else can I look at, this laptop wasn't cheap, I expected it to last atleast several years. Appears I do have basic warranty...
