Alienware Area-51 m5550 Technical Reference

Power Button Action

The notebook PC’s power button can be set to turn off the system or activate the suspend mode.

Go to [Start > Control Panel] and click on the battery options under the mobile section and click on “Choose what the power buttons do” on the side bar. In the pull-down menu, select how you wish the power button to work as.

Note: The actual dialogue box may appear slightly different than the one shown above.

Warning: In the “When I close the lid of my portable computer” pull-down menu, DO NOT select “Do nothing” – otherwise the system will still run at high speed while the processor’s fan grill is fully blocked by the closed LCD panel. The heat will damage the LCD panel.
