When a Device Will Not Wake up from Sleep Mode

To resolve this issue and resume computer operation, use one of the following methods:

1) Press the SLEEP keyboard shortcut (if any in Windows 10 or 11).

2) Press a standard key on the keyboard.

3) Move the mouse.

4) Quickly press the power button on the computer (at least two times; do not push and hold the button).

5) If the issue persists, unplug the monitor's power cable, wait 10 seconds, and then plug it back in. This can help reset the monitor's internal components.

6) Ensure the correct input source (e.g. HDMI, VGA) is selected on the monitor's display settings.

7) If all else fails, try a hard reset by holding the power button on the computer for about 5-10 seconds until it shuts down, then power it back on.
