Dimension 5150 Power light is amber, cooling fans on, monitor says no signal, vidio cables OK. Just will not come out of sleep mode. Any suggestions?? Thanks, Bob
Unplug the computer and hold the power button for a few seconds, then try to start it up. If the system seems to be starting up but you're still getting no signal, it may be a video card problem.
Please post back and let me know if you need more help.
Finally got around to replacing the power supply. Nothing changed - computer will still no come out of sleep mode.
Will try it. Processor and power supply fans come on and "no signal" appears on monitor but on button stays yellow and nothing happens. No startup light on keyboard either.
Thanks for reply. Bob
