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. Also make sure you disabled the
built-in VGA controller by changing the setting of jumper JP21;
see “Changing the Jumper Settings” in Chapter 3 for
instructions. In addition, check that you set the correct display
type for the Video System option in SETUP; see “Using the
System Setup Option” in Appendix B.
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.
The power switch is on but the power light is not on.
If the monitor is Energy Star compliant, it may be in a power-
saving mode. Press a mouse button or a key on the keyboard to
activate the monitor.
