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.
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 power
button for less than 4 seconds (the Power LED will blink green while in Standby mode, in Hibernate
mode it will be off).
Brightness - Check the brightness of the screen by pressing the Fn + F8 or F9 keys to adjust the brightness
(see “Opening the LCD” on page 3 - 2 ).
Display Choice - Press Fn + F7 to make sure the system is not set to “external only” display (see “At-
taching a Monitor (CRT)” on page 3 - 7 ).
Boot Drive - Make sure there are no floppy disks in any attached floppy disk drives 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 ”).
