T520 Restarts instead of Shutdown

[kafisheh]

My T520 Win-7, 64-bit is all fine, except just recently has been restarting on its own when I shut it down.

It fully shuts down, then after a second it starts up again.

I've made sure the Power button is intact, and the fingerprint reader is clean; assuming either might have been in fault.

I have rolled back my laptop to a previous "last best configuration", to undo a recent update, but nothing seems to have solved the problem.

Please help, for my laptop hasn't went to a full shutdown in 4 days already.

Thanks.

If you're shutting down and via the start button and there is a restart. Note if the Think start BIOS is displayed indicating a cold start as opposed to a soft restart in which it does not show up.

Wake up on LAN is about the only other thing that can do that.

Hi, thanks for the reply, but I guess that wasn't a olution was it?

My laptop hasn't been shutting down for quite a while now.

Well you haven't returned to the board in 5 days with feedback.

Start it in Safe Mode and then shut it down and see if it stays off.
