microprocessor speed, and the monitor, if the monitor
supports Display Power Management Signaling (DPMS).
Level-1 power management occurs after the shortest
period of inactivity. You can specify Levels 2 and 3 if
you want the power consumption to be reduced further
after longer periods of inactivity. The following
power-management options are available at each level:
System power:
If you select Off, the system power
will be turned off after the specified period of
inactivity. Off is then automatically selected for any
subsequent levels.
Processor speed:
With this option, you specify a
percentage reduction in microprocessor speed. At
any subsequent levels, the microprocessor speed must
be the same or it must be reduced further. Any
activity on a monitored interrupt returns the
microprocessor to full speed.
Display:
There are three reduced-power states for
the monitor:
– Standby: In this mode, the screen is blanked, but
the screen image is restored immediately when
any activity is detected.
– Suspend: The monitor uses less power in this
mode than in the 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 power switch on the monitor. On some
monitors, you might have to press the power
switch twice.
Attention
If a device, such as a monitor, does not have
power-management capabilities, it can be damaged
when exposed to a reduced-power state.
Before you make energy-saving selections for your
monitor, check the documentation that comes with
your monitor to see if it supports Display Power
Management Signaling (DPMS).
With the Hard File option, you can enable the hard disk
drive to “spin down” (a shutdown of the drive motor)
after about 20 minutes of inactivity on the drive. When
you attempt to read from or write to the disk, full power
is returned to the hard disk drive within a few seconds.
Setting Advanced Power Management Features
To set advanced power management features:
1. Start the Configuration/Setup Utility program (see
“Using the Configuration/Setup Utility Program” on
page 16).
2. Select Advanced Power Management from the
Configuration/Setup Utility menu.
3. Be sure APM BIOS Mode is set to Enabled.
4. Select Automatic Hardware Power Management.
5. Set Automatic Hardware Power Management to
Enabled
