The following table describes the parameters found in this menu. Parameter ACPI Function ACPI Suspend Type Run VGABIOS if S3 Resume Power Management Video Off Method Video Off In Suspend Suspend Type MODEM Use IRQ Description Options Enabled/Disable ACPI Function. Enabled Disabled This item specifies the power saving modes for ACPI function. Options are: S1/POS: The S1 sleep mode is a low power state. In this state, no system context is lost (CPU or chipset) and hardware maintains all system context. S3/STR: The S3 sleep mode is a lower power state where the information of system configuration and open applications/files is saved to main memory that remains powered while most other hardware components turn off to save energy. The information stored in memory will be used to restore the system when a "wake up" event occurs. S1/POS S3/STR When ACPI Suspend Mode is set to S3 or S1&S3, users can select the options in this field. Selecting [Yes] allows BIOS to call VGABIOS to initialize the VGA card when system wakes up (resumes) from S3 sleep state. The system resume time is shortened when you disable the function, but system will need an AGP driver to initialize the VGA card. Therefore, if the AGP driver of the card does not support the initialization feature, the display may work abnormally or not function after resuming form S3.
