4: Operating the System
1.
Turn the Power keyswitch right momentarily (less than 1 second). Automatic
Shutdown runs and the shutdown timer begins counting down.
2. Select a shutdown option and click Start Shutdown.
3. If you chose an option that requires you to power down the system manually, you can do so when prompted that it is safe to do so.
Caution:
The AC power cord for this unit is the service disconnect. To remove AC power from the system, you must unplug the system power cord from its AC power outlet.
For more information on starting and stopping the operating system, see the operating system documentation and Help.
Observing Operating Precautions
Observe the following precautions when operating the system:
• When restarting the system, use the operating system controls instead of turning the power switch off and on. Use the power switch only when instructed, or as the last alternative for restarting the system.
• Never turn off power to the base unit when the disk access LED is lit.
• After turning off power to the base unit, wait at least 30 seconds before turning the power on again. This allows the power supply to stabilize and the disk drives to stop spinning.
Using the Keyboard
The system’s PS/2-compatible keyboard includes the following features:
• 104 standard keys, including special application function keys ( f1
through f12
), arrow keys for moving the cursor, and numeric keys in a keypad.
• Special keys for use with Windows operating systems. Pressing the left or right
Windows key (on either side of the space bar) displays the operating system Start menu and Taskbar. Pressing the Application key (to the right of the space bar) displays an application-specific pop-up menu.
