Windows 10: Laptop unable to shutdown/restart. Creates deafening sound.

I have been dumbfounded by an issue as a work laptop refuses to shutdown or restart. The screen is completely off, keyboard seems to be unresponsive, but the light on the power button is on and occasionally blinks. The most alarming issue however, is a loud chirping/wailing sound coming out of the laptop. I do not have any application open, so a sound glitch is unlikely in my opinion. Also note that prior to this, the laptop would boot into a BIOS menu, a coworker did not know what to do with it and before I could try and address the issue so she had simply left it at the BIOS menu. It is stil

Logoff, Logon, shutdown, restart, startup sounds not playing


I'm running Threshold 2 of Win10. It seems the Startup Sound is working again. Previously, even checked it would only play intermittently on a warm boot, not a cold one. Now it seems to work all the time. There is a 3rd party app that lets you change the Startup Sound to whatever you want, without you having to go through the hack steps.

The Exit Windows sound is another matter. Even enabled via the Registry and reappearing in the Sound list, selecting a sound for that does not make it play at shutdown.

Do you have a link to download the threshold 2?

 

Shutdown sound notification


A truncated system notification sound will be heard if the start menu POWER=Shutdown or the Start Menu right click "shut down or sign out"=shutdown is used. Testing the default control panel sounds has the system notification be the closest to the brief musical sound I hear. There is not an actual 'shut down sound' displayed in the list.
A short cut icon with the shut down script 'C:\Windows\System32\shutdown.exe -s -t 00' does not produce this sound.
The event viewer report at shutdown time displays the Client OOBE ID 3 stopped. (Why this is listed as an error is a mystery since the security would be stopping if the machine is shut down???but that is the only event listed)

This little sound started after the Jan updates.
Previous to Jan and Feb updates I could not expect a complete shutdown if an external drive was plugged in.
After the recent updates the external drive can be left plugged in and the shut down does not restart.
That little sound is nothing compared to restart but I wondered if it needed to be investigated.
