4-10 Management

Set all options for the System Management feature in this section.

ACPI Settings

ACPI Sleep State

This feature selects the ACPI Sleep State that the system will enter into

when the suspend button is activated. The options are Suspend Disabled,

and S3 (Suspend to RAM).

High Precision Event Timer

Select Enabled to activate the High Precision Event Timer (HPET) that

produces periodic interrupts at a much higher frequency than a Real-time

Clock (RTC) does in synchronizing multimedia streams, providing smooth

playback and reducing the dependency on other timestamp calculation

devices, such as an x86 RDTSC Instruction embedded in the CPU. The

High Performance Event Timer is used to replace the 8254 Programmable

Interval Timer. The options are Enabled and Disabled.
