dual-state power button

With Advanced Configuration and Power Interface (ACPI) enabled for Windows, the power
button can function either as an on/off switch or as a suspend button. The suspend feature does
not completely turn off power, but instead causes the workstation to enter a low-power standby.
This allows you to quickly power down without closing applications and to quickly return to the
same operational state without any data loss.
To change the power button's configuration, complete the following steps:
1. Access the Computer Setup menu.
2. Select Power > Energy Saver. Select Minimal or Advanced to turn on the Energy Saver
Options menu.
3. Select Power > Energy Saver Options. Set the power button configuration to either On/Off or
Suspend/Wakeup, as desired.
4. See the "Computer Setup (F10)" section of this guide for more detailed information about
the features of Computer Setup.
5. Select File > Save Changes and Exit.
After configuring the power button to function as a suspend button, press the power button to put
the system in a very low power state (suspend). Press the button again to quickly bring the system
out of suspend to full power status. To completely turn off all power to the system, press and hold
the power button for four seconds.
If you have selected the "Blink LED during Energy Save" option in Computer Setup, the
NOTE:
power-on light will blink green once every two seconds while the workstation is in suspend. See
to the "Computer Setup menu" section earlier in this chapter for more information on using
Computer Setup.

advanced customization of the power management settings is available through Computer Setup.
The power saver and power management features are not supported on Linux-based
