ACPI controls the Advanced Configuration and Power Interface. If the operating sys-
tem supports ACPI and ACPI is toggled On, pressing the power button momentarily
places the system in a power-saving mode. You can turn the system completely off by
pressing and holding the power button for more than 4 seconds. When ACPI is acti-
vated (On), IRQ 9 is not available for use by expansion cards.
When ACPI is toggled Off, pressing the power button turns the system completely
off. When ACPI is not activated (Off), IRQ 9 is available for use by expansion cards.
NOTE: If your operating system does not support ACPI, the computer will not go into
power-saving mode when you press the power button, even if ACPI is toggled to On
in the System Setup program.

Thermal Power-off, when enabled, sets a timer to shut down the system approxi-
mately 3 minutes after the system BIOS detects a temperature that exceeds preset
levels for a processor or hard-disk drive. This feature provides a safeguard in the event
that another shutdown utility, such as the Dell AutoShutdown service, is not installed
or fails to shut down the system after a preset temperature level is exceeded.
