The power switch operates in two modes: immediate and AutoShutdown. When the system is off, the power switch always acts in immediate mode—that is, when the switch is pressed, the system turns on immediately.

When the system is on and the AutoShutdown service is installed, the power switch operates in AutoShutdown mode. Pressing the power switch signals the operating system to perform an orderly shutdown (reducing the possibility of data loss and file corruption) before removing power from the system. During the shutdown sequence, ,I<RXU2SHUDWLQJ6\VWHP/RFNV8Sthe power indicator on the computer blinks.

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 inter- nal components. f 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
