9.4.5 ACPI Submenu
Feature Options Description
ACPI no option Describes the ACPI features.
Hibernation Support Disabled
Enabled
Enable or disable system ability to hibernate (operating system S4 sleep state). This option may not be ef
fective with
some operating systems.
ACPI Sleep State Suspend Disabled
S3 (Suspend to RAM)
Select the state used for ACPI system sleep/suspend.
Lid Button Support Disabled
Enabled
Congure COM Express LID# signal to act as ACPI lid button.
Sleep Button Support Disabled
Enabled
Congure COM Express SLEEP# signal to act as ACPI sleep button.
S3 Video Repost Disabled
Enabled
Enable or disable video BIOS re-post on S3 resume. Required by some operating systems.
S3 USB Wake Disabled
Enabled
Enable or disable ACPI Wake events generated by USB devices.
CPU Thermal Monitoring Enable for ACPI and CGOS
Enabled for CGOS
Disabled
ACPI Monitor will use System Management Interrupts (SMI) for accessing the Digital Thermal Sensor located on a
Machine Specic Register (MSR). CGOS access the Digital Thermal Sensor MSR.
Note: Both operations would be problematic for some Operating systems.
Critical Trip Point POR, 70, 75, 80, 85, 90, 95,
100, 105, 110, 115, 120, 125
°C, Disabled
Species the temperature threshold at which the ACPI aware OS performs a critical shutdown. The option “POR” is
for Cedar Trail Processor at 100° C trip point.
Active Trip Point 55, 60, 65, 70, 75, 80, 85, 90,
95, 100, 105, 110, 115, 120,
125 °C, Disabled
Species the temperature threshold at which the ACPI aware OS turns the fan on/off.
Passive Trip Point 55, 60, 65, 70, 75, 80, 85, 90,
95, 100, 105, 110, 115, 120,
125 °C, Disabled
Species the temperature threshold at which the ACPI aware OS starts or stops CPU clock throttling. This method of
Passive cooling is not recommended. The preferred method of passive cooling is the setting of the TCC active offset
in CPU Conguration menu.
