The yellow-power color is an indication of a power problem. Either the computer is getting inadequate power from the wall (perhaps you have it plugged into a burned-out power strip), or the outlet is bad on the wall, or the power supply in the computer is failing. Address those three areas and see what happens.

Hope this helps

Amber power button usually is associated with ether power supply or motherboard issue. U can try to unplug it from power for about 30 min and see what happens. Also try to turn it on with all the extras removed like keyboard and mouse. If this does not work i would take in to repair shop unless u have testing tool for power supply and know how to do it. Good luck.

Dell c521 won't start blinks amber


A possible power supply failure has occurred. The system has not received a Power Good signal from the power supply. In other words you either have a defective power supply or a device in the computer (i.e. sound or video card) is shorting out the power supply.

C521, get the orange light, fan turns on and it's just steadily orange light


A steady or Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Dell c521 motherboard diagrams problems


Per Dell's support site: If the power light is a solid amber, a device might be malfunctioning or incorrectly installed.

Turn off the computer and unplug from power:

I would remove and unplug everything except the memory and video card. Then plug the computer back in.
If it posts (dell screen and then a hard drive warning), turn off the computer and start reinstalling each component one at a time and turn on between each install. Hopefully one compenent will fail and you will know what is bad and needs replacing.
If the computer still had the amber light, remove one of the memory modules (hoping you have 2) and try again. If it still fail exchange the modules. If this works you have a bad memory chip, reinstall the rest the componets to double check and power on. Replace the bad chip.
If the computer still fails on both modules, remove both, you should now get a memory beep code, if not then the video card is most likely bad and will need to be replace.

Hope this helps

Hi - our dell dimension c521 is stuck in power save mode. The light on the monitor is solid orange and will not respond to the keyboard or mouse


A solid amber light indicates a pre-POST failure has occurred. The system has received a Power Good signal from the power supply so it's not a power supply issue. HERE is the documentation that tells what the lights mean and possible solutions.

On my Demension C521, lightening struck it and when I press the power button, it won't turn on. However, the amber light on the back where you plug the ethernet cable into lights up. Could this just be the...


Yes very likely it is just the power supply... These are one of those things that you have to fix piece by piece. But I would replace the power supply you should be back up and running in no time.

check on system lights... what are the diagnostic lights telling you??
if the 4 lights are off you may have a problem with the led itself or the powersupply is just messing with your head.

Amber light on power button of Dell Dimension 4500


ok - the amber light of doom on a dell means one of two things - either your power supply is pooched - or your motherboard, If under warranty dell will send out a friendly tech to replace them - if not it will cost you a bit. get the price and consider if it worth upgrading instead. Contact your dell rep or dell tech support and see what they say

cheers Pete
