Basic Hints and Tips
Many of the following may seem obvious but they are often the solution to a problem when your computer
appears not to be working.
• Power - Is the computer actually plugged into a working electrical outlet? If plugged into a
power strip , make sure it is actually working. Check the LED Power Indicators (see “LED
Power & Communication Indicators” on page 2 - 6 ) to see the computer’s power status.
• Connections - Check all the cables to make sure that there are no loose connections anywhere.
• Power Savings - Make sure that the system is not in Hibernate or Standby mode by pressing the
Fn + F4 key combination (see “System Resume” on page 3 - 18 ), or by pressing the power but-
ton, to wake-up the system.
• Brightness - Check the brightness of the screen by pressing the Fn + F8 and F9 keys to adjust
the brightness (see “Advanced Video Controls” on page 3 - 2 ).
• Display Choice - Press Fn + F7 to make sure the system is not set to “external only” display (see
“Display Devices” on page 3 - 7 ).
• Boot Drive - Make sure there are no floppy disks in the drive when you start up your machine
(this is a common cause of the message “ Invalid system disk - Replace the disk, and then press
any key ” / “ Remove disks or other media. Press any key to restart ”).
