Power Management (300-700 Series)
Power Management 300-700 Series
Power management reduces the power consumption of certain components of the
computer such as the system power supply, processor, hard disk drives, and some
monitors (if monitor supports DPMS). Advanced Power Management and Rapid Resume Manager are features of some
Advanced Power Management
Energy-saving settings can be viewed and changed by using the Advanced Power Management
menu in the Configuration/Setup Utility program.
If a device, such a monitor, does not have power-management
it can be damaged when exposed to a reduced-power state
Before making energy-saving selections for the monitor, check the documentation supplied with the monitor to
see if it supports Display Power Management Signaling (DPSM).
Automatic Hardware Power Management Features:
There are three levels of specified time that the computer must be inactive before the power management options that are
selected take effect. Select the amount of time that is offered within each level.
- Level 1 Set time from 5 minutes to 4 hours.
