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.
