Re: Notebook restarts after shutdown

Press (Windows Key)+R and type in regedit and hit enter.  Locate the following key:

Location: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Double Click on "PowerdownAfterShutdown"

Then,
Change it to "0" if it is "1" OR
Change it to "1" if it is "0".

And hit Enter.

Then restart the computer and after it restarts try to shutdown again.  Hopefully this will work for you. :)

***If this doesn't work make sure you change the value in regedit back to what it was originally***
