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
Fn + F4
key combination (see
“System Resume” on page 3 - 20
), or by pressing
the power button, to wake-up the system.
•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
“Attaching a Monitor” on page 3 - 9
).
•Boot Drive:
Make sure there are no floppy disks in any floppy disk 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
”).
