Depending on the operating system, pressing the power button may cause the computer to enter a
low-power or "standby" state instead of automatically turning the power off. This allows you to
conserve energy without closing software applications; later, you can start using the computer
immediately without having to restart the operating system and without losing any data.
CAUTION:
To force the computer off manually and bypass the "standby state," press and hold the power button
for four seconds.
On some models, you can reconfigure the power button to work in On/Off mode by running Computer
Setup. Refer to the Maintenance and Service Guide (English only) for more information about using
the Computer Setup utility.
