Power and Power-Up Modes
Panel power on/off
You can set up your computer so that power turns off automatically when
you close the computer’s LCD display panel. When you open the
computer’s LCD display panel, power turns on in Standby or Hibernation
mode but not in boot mode.
System Auto Off
This feature turns the system off automatically if it is not used for a set
duration. The system shuts down in Standby mode or Hibernation mode in
Windows.
If the panel power off function is enabled and you manually shut down
Windows, do not close the computer’s LCD display panel until the shut
down process has been completed.
