Operating system not found— Call Dell for technical assistance. See "Contacting Dell" in the Dell Owner's Manual for the correct number to
call.
Insert bootable media— The operating system is trying to boot to a nonbootable floppy disk or CD. Insert a bootable floppy disk or CD.
Non-system disk error— There is a floppy disk in the floppy drive. Remove the floppy disk and restart the computer.
HINT: See the documentation that came with your monitor for fault indications and troubleshooting procedures specific to your monitor.
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 are not green, call Dell for technical assistance. See "Contacting
Dell" in the Dell Owner's Manual for the correct number to call.
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).
Adjust the contrast and brightness— See the documentation that came with your monitor for instructions on adjusting the contrast and
brightness.
Move the subwoofer away from the monitor— If your speaker system includes a subwoofer, ensure that the subwoofer is at least 2 ft
(60 cm) away from the monitor.
Move the monitor away from external power sources— Fans, fluorescent lights, halogen lamps, and other electrical devices can cause the
screen image to appear "shaky." Turn off nearby devices to check for interference.
Rotate the monitor to face a different direction— Eliminate sunlight glare, which can cause poor picture quality.
Degauss (demagnetize) the monitor— See the documentation that came with your monitor.
Run the monitor self-test— See the documentation that came with your monitor.
Restore the recommended settings— Restore the original resolution and refresh rate settings. See the Tell Me How help file for instructions.
Check for additional adjustments— See the documentation that came with your monitor for any additional adjustments that your monitor
may require.
