ACPI Suspend Type (S1&S3)

mode is a suspend to RAM, i.e., the system shuts down with the exception of a refresh
current to the system memory.
Video Off Method (DPMS Support)
This item defines how the video is powered down to save power. This item is set to DPMS
(Display Power Management Software) by default.
HDD Power Down (Disabled)
The IDE hard drive will spin down if it is not accessed within a specified length of time.
Soft-Off by PBTN (Instant-Off)

software power down. In a software power down, the system can be resumed by Wake Up
Alarms. This item lets you install a software power down that is controlled by the power
button on your system. If the item is set to Instant-Off, then the power button causes a
software power down. If the item is set to Delay 4 Sec. then you have
to hold the power button down for four seconds to cause a software power down.

HPET Support (Disabled)
