Setting Power–Management Features
With power–management, the computer and monitor (if the monitor
supports DPMS) can be set to go into a reduced-power state if they are
inactive for a specified length of time.
Ÿ
Time to Low Power: With this option, you can specify the amount of
time that the computer must be inactive before power–management
features take affect. You can select from 5 minutes to 1 hour.
Ÿ
System Power: With this option, you can select On if you want the
computer to remain on, or Off if you want the computer to shut down.
Ÿ
Display: You can use this option to select one of the following
reduced-power states:
– Standby: In this mode, the screen is blanked, but the screen image
is restored immediately when any activity is detected.
– Suspend: In this mode, the monitor uses less power than in
Standby mode. The screen is blanked, but the screen image is
restored within a few seconds after any activity is detected.
– OFF: In this mode, the monitor power is turned off. To restore
power to the monitor, you must press the monitor power switch.
On some monitors, you might have to press the power switch
twice.
If OFF is selected, you must specify the Time to Display 'off'. You
can select 5 minutes to 1 hour.
Note: Time to display off is the amount of time after the
reduced-power state begins until the display turns off.
– Disable: In this mode, the monitor is unaffected by the power
management settings.
Ÿ
IDE Drives : You can use this selection to specify if the IDE drives
should be enabled or disabled when power management options take
affect.
