Power management features
Your computer comes with built-in energy-saving capabilities. You can
view and change energy-saving settings using the power management
menu in the Configuration/Setup Utility program. This section describes
the power management features in your computer and provides instructions
for using these features.
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).
