ON/OFF BUTTON
The On/Off button (3) is used to power up/down the Notebook.
The power supply indicator
gives information on the operating
status. The notebook will always be switched off, if the main
switch is pressed for more than 4 seconds.
 WARNING! Do not switch off your notebook while
the hard disk or the optical drive is running and
the corresponding media activity LEDs are lit.
Otherwise data may be lost. To protect the hard
disk you should always wait for 20 seconds after
powering down the notebook before powering it up
again.
