Monitor Problems
There is no display on the screen.
Check that the monitor’s power switch is on and that its power
light is on.
Also, the computer may be in a power-saving mode. When you
press a mouse button or a key on the keyboard, see if the
monitor displays an image.
The power light is on, but you still do not see anything on
the screen.
Press a mouse button or a key on the keyboard to see if the
monitor or computer is in a power-saving mode. Also, check
the brightness and contrast controls.
If you still do not see anything on the screen, make sure the
monitor is securely connected to the computer.
If you installed a display adapter card, make sure your monitor
type matches the card type. Make sure you disabled the built-in
VGA controller by changing the setting of jumper JP50; see
“Changing the Jumper Settings” in Chapter 4 for instructions.
Also be sure you set the correct display type for the Video
System option in SETUP. (See “Using the System Setup
Option” in Chapter 2.)
If you are running an application program, see if you need to
set up the program for the type of monitor and display adapter
you have. Also make sure you are using the appropriate
monitor and display adapter for your software.
