In the BIOS Setup Utility, you can set up an Advance Power Management system (APM 1.2) to reduce the
amount of energy used after specified periods of inactivity. The setup menu supports:
Full On State
®
Standby State with Partial Power Reduction
®
Suspend State with Full Power Reduction
®
In addition you can enable an ACPI 1.0 support in the BIOS setup utility, if you intend to use an
operating system supporting the Advanced Configuration and Power Management Interface. For logical
reasons it is required to use an ATX power supply with the ACPI feature.
The following states are supported from the system:
S0 (Working)
®
S1 (Sleeping with processor context maintained)
®
S3 (Suspend to RAM)
®
S5 (Soft off)
®
The state S2 (sleeping with processor context not maintained) is not supported. The state S4 (Save to
Disk) is a matter of the used operating system.
