Chassis Intrusion; Thermal Power-Off; Keyboard Errors - Dell Precision 410 User Manual

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.
Chassis Intrusion displays the status of the system's chassis intrusion detector.
If the chassis is opened, the setting changes from Not Detected to Detected and the
following message is displayed during the boot routine at system start-up:
Alert! Cover was previously removed.
To clear this field and allow future intrusions to be detected, make sure the chassis
cover is closed, and then enter the System Setup program during the system's POST,
as described earlier in this chapter. At Chassis Intrusion, use the left- or right-arrow
key to choose Reset. This action changes the setting to its default, Not Detected.
NOTE: If a setup password has been assigned by someone else, contact your net-
work administrator for information on resetting the chassis intrusion detector.
Thermal Power-off, when enabled, sets a timer to shut down the system approxi-
mately 3 minutes after the system BIOS detects an overtemperature condition 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 the system down after an overtemperature condition.
Keyboard Errors enables or disables reporting of keyboard errors during the POST,
which is a series of tests that the system performs on the hardware each time you
turn on the system or press the reset button.
This option is useful when applied to self-starting servers or host systems that do not
have a permanently attached keyboard. In these situations, selecting Do Not Report
suppresses all error messages relating to the keyboard or to the keyboard controller
during POST. This setting does not affect the operation of the keyboard itself, if a key-
board is attached to the computer.
System Password displays the current status of your system's password security fea-
ture and allows you to assign and verify a new password. No one can assign a new
password unless the current status is Not Enabled, which is displayed in bright
characters.
