Power Management through ENERGY STAR quali-
fied monitors (Optional)
The power management feature allows the computer to initiate a low-power or “Sleep”

monitor. To take advantage of these potential energy savings, the power management
feature has been preset to behave in the following ways when the system is operating
on AC power:
Turn off the display after 15 minutes
Initiate Sleep after 30 minutes
Waking the System Up
The computer shall be able to wake up from power saving mode in response to a com-
mand from any of the following:

the keyboard.
Energy Saving Tips:
Turn off the monitor by pressing the LCD power button after a period of user
inactivity.
Tune the settings in Power Options under Windows OS to optimize your PC’s
power management.
Install power saving software to manage your PC’s energy consumption.

would be left unused for a certain time to achieve zero energy consumption.
