Tun off monitor problem

[Jeremy]

Under power management I have the "Turn off monitor" option enabled if
my computer is idle for 20 minutes. And all I needed to do to turn on
the monitor again was just to move the mouse.

However, something has gone wrong since a week ago and I'm no longer
able to turn on the monitor by moving the mouse. Instead, I have to
restart windows by pressing the reset button.

What could have caused this problem?

TIA

Jeremy

Does pressing a key on the keyboard wake up the machine? In the Device
Manager open the Properties for the mouse and go to the "Power
Management" tab. Uncheck "Allow the computer..." here.
