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 Performance 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 Disabled and Enabled.
WHEA Support
This feature Enables the Windows Hardware Error Architecture (WHEA) support for the
Windows 2008 (or a later version) operating system. The options are Disabled and Enabled.
