Caution - Be careful when making changes to the system BIOS, as some changes can cause your system to malfunction.

2.5 Powering Off the Workstation

1. Save your data and close any open applications.

2. Read both of the following power-off options, and then follow one of the options to turn off the workstation.

In most cases, this initiates an orderly shutdown of the operating system and shuts off the workstation power.

Caution - To avoid data loss, use the first option whenever possible.

This option shuts down the power to the workstation but does not initiate an orderly shutdown of the operating system. This option might result in data loss.

If the proceeding options do not power off the workstation, turn the power switch on the back panel to the Off ( 0 ) position.

After powering off the workstation, wait at least four seconds before powering on the workstation again.
