The problem I'm having is that occasionally (and without warning) my T520 will fully power off and restart. No bluescreen, no error, nothing in the event log.
I'm really at a loss as to what is going on on here
Thanks for the help,

I would suggest you to please uncheck the automatic restart, and then update the Bios of your notebook from the below mentioned web link.
After this, please restart the notebook and check if the issue resolved.

START- Right click on COMPUTER- PROPERTIES - ADVANCED SYSTEMS SETTING.
Uncheck Automatic Restart under system failure.

My laptop (also a T520) has started having the same issue. Starting a couple months ago, blue screens began popping up with a USB bugcode, so I disabled all my USB ports (there was an unknown USB device listed, but nothing was plugged in). I don't use external mice/keyboards, so it hasn't been an issue yet.
BUT, ever since I stopped the blue screens, I've been getting the occasional power off and restart. I checked my system settings and "automatically restart" was already unselected. It's happened only two or three times - so far.
The laptop is around 2.5 years old. Pretty sure the fan has gone kaput or is running extremely weakly.
