New HP ProBook 445 G8 Notebook PC restarts when I try to shutdown

[kp1555]

My new HP ProBook 445 G8 Notebook PC restarts when I try to shutdown. I have to shutdown from the Windows welcome screen. I have it plugged into a power outlet all the time. I checked the power/sleep settings and can't find anything obviously wrong there. Any help would be greatly appreciated.
