Windows 10 did a security update on 1/9 and 1/10.  Last night the computer was acting strange, so I went to do an undo to the security update.  It ran very slowly for a time.  I was unable to turn the computer off.  This morning the battery was empty.  I plugged it in, but on checking it just now the screen is dark.  The mouse arrow is visible and moves on the empty screen.  I am unable to power on or off.  This message is being sent on another computer.  Can you give suggestions on how to handle this problem?  Thanks.

    first of all to a long press on power button until it shutdown then if it's a laptop do a battery reset too:

    if you still have the black screen, try this:
    at boot press ALT+F10 or after entering your password to login, keep pressing Shift key, this will start Acer/windows recovery.
    From the Recovery screen
    Click on Troubleshoot.
    Click on Advanced Options.
    Click on Startup Settings.
    Click on Restart.
    The PC will now reboot to the Startup Settings screen.
    Press 4 to Enable Safe Mode as prompted.



    once in Safe mode, go to Device manager, click on Display adapters, right click on your VGA  and choose uninstall(tick to uninstall software too).

    reboot normally and check if black/blank screen is fixed.
