Lenovo ThinkPad T460 NM-A581 power on only for few seconds
Hi all,
any Idea what the problem can be?
Lenovo ThinkPad T460 when i plug the AC Adapter, the board is only for few seconds on, after that is dead, no 3 + 5V presents.
First + second mosfets have 20v, Systemrail 20v too.
had someone such problem? i have this problem with few Lenovo Boards, T460, T460s, X260...
Thanks for any help... -
