Hello everyone, can anyone help me out with my T520 not shutting down? The machine came with Win7Pro installed, I reformatted and installed fresh copy of windows but same problem. Then i went thru setting up the power options , same think it won't shut down. Now i've upgraded to Win10 Pro thinking that it has better power management no go again. It acts more like restart then shut down, it will power down for a second but immediately will power backup

At this point i'm at lost

Any help will greatly appreciated.
John
