This section contains the various options through which one can control the system's automatic power management settings.
Global Power Management Setting
This is a setting that, when present, enables or disables power management globally. When set to “Disabled”, the other settings will either be locked out (so they cannot be changed) else they will simply be ignored.
Video Power Down Mode
This controls the method used to put the monitor into low-power mode. The typical options for this setting are:
- DPMS: This option is selected if your monitor supports the DPMS standard for monitor power management. This is the most preferred and usually the default setting. Most modern monitors support DPMS (Check in the monitor manual).
- V/H Sync+Blank: When this option is selected, this causes the video card to shut down the vertical and horizontal sync signals to the monitor, as well as sending blank data to the monitor.
- Blank Screen: When this option is selected, it causes the monitor to be blanked.
Video Power Down Timeout
This setting controls / manages as to how long the system must be idle for the video to be powered down. It is specified in minutes, or set to “Disabled”.
