If the power indicator blinks when you press the power switch, but the system does
not turn off, your operating system may have locked up. To turn off the system in this
situation, either press the power switch a second time or press the reset button.
NOTE: This scenario (a locked-up system with the AutoShutdown service active) is
the only situation in which pressing the reset button turns off the system without
rebooting it.

The Dell ThermalShutdown service helps protect components such as the system
processor and the primary hard-disk drive from damage due to overheating. It can
also protect your system data from loss or corruption resulting from a thermal-related
system shutdown.

When installed, the service uses sensors to monitor the temperature of critical
internal components. If a sensor detects a thermal event, the system first performs
an orderly operating system shutdown and then turns itself off. During the shutdown
phase, the power indicator flashes and a screen message notifies the user that the
system is shutting down.
If the ThermalShutdown service is unable to shut down the system, the system
will be shut down if Thermal Power-off is enabled in the System Setup program.
(See “Thermal Power-Off” in Chapter 3 for more information.)

The Auto Power On utility (available for MS-DOS only) enables your system t o
automatically perform routine tasks in your absence. For example, you might want
your system to turn on at night and perform a backup procedure. To use the utility,
you need to create a batch file containing the command(s) or program(s) that you
want performed in your absence. The Auto Power On utility determines whether
system power was turned on by the power button or by the Auto Power On setting in
the System Setup program and passes this information on to your batch file, which initiates the
appropriate commands at system start-up. See “Auto Power On” in Chapter 3 for information
on setting Auto Power On in the System Setup program.
