Power management
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. Advanced Power Management and Rapid Resume
¬
Manager are features
of some personal computers.
Automatic configuration and power interface (ACPI) BIOS
Being an ACPI BIOS system, the operating system is allowed to control the power
management features of the computer and the setting for Advanced Power
Management (APM) BIOS mode are ignored. Not all operating systems support
ACPI BIOS mode.
Advanced Power Management
Energy-saving settings can be viewed and changed by using the Advanced Power
Management menu in the Configuration/Setup Utility program.
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 making energy-saving selections
for the monitor, check the documentation supplied with the monitor to see if it supports
Display Power Management Signaling (DPMS).
