CHECK THE VIDEO CABLE CONNECTION—Check for bent pins (most video
cable connectors have missing pins, but not bent pins). Ensure that the video
cable is connected as shown on the START HERE sheet for your computer.
PRESS THE MONITOR POWER BUTTON—Be sure that you firmly pressed the
monitor power button.
CHECK THE POWER LIGHT—When the power light is lit or blinking, the
monitor has power. If the power light is blinking, press a key on the keyboard or
move the mouse.
TEST THE ELECTRICAL OUTLET—Ensure that the electrical outlet is working
by testing it with another device, such as a lamp.
SWAP THE COMPUTER AND MONITOR POWER CABLES—Swap the
computer and monitor power cables to determine if the power cable is defective.
TEST THE VIDEO EXTENSION CABLE (IF USED)—If you are using a video
extension cable and removing the cable solves the problem, the cable is defective.
TEST THE MONITOR—If another monitor is available, connect it to the
computer.
CHECK THE BACK PANEL LIGHTS—If all four lights below the serial
connector (see page61) are not green, call Dell for technical assistance (see
page100).
CHECK THE POWER PROPERTIES—See the Tell Me How help file or search
for the keyword standby in the Help and Support Center (Help in Windows
2000). To access help files, see page26.
