Thinkpad 450 randomly resets when connected to external battery

I have a t450 and it came with windows 8, after some months I updated it to win 10.

It worked very well, then after a couple of months of inactivity when I turned it on again it started to randomly resetting, after 2, 5, 10 minutes it resets, then again and again. Its impossible to work.


But only when I have it connected to the external battery.

If I’m using the internal one or AC all is good.


I thought it was a problem with the external battery, but always thought it weird because if I don’t enter windows (stay in bios screen) the computer stays on for hours.

Called Lenovo, they send a technician, and on that day during the 30m he was here it didn’t reset ... obviously.


Ended up buying a new battery online, and it arrived this week... but it continues to reset randomly.

All the drivers are up to date, all Lenovo software is installed, the Lenovo technician didn’t find any thing "off place".


Any ideas?


Thank you
