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.
