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.

My dell dimension c521 power button is amber color and the computer will not turn on. what can i do?


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.

Can you get a bigger psu for dell dimension c521 that will fit inside the case


Hello aprilmick

I think you can.
the case dimension for your dell PC is H: 15.8" (40.13 cm) W: 4.5" (11.43 cm) ---> the standard power supplies have a width of less than 10cm.
D: 14.2" (36.07 cm) ---> the standard power supplies have a debth of almost 15cm.

Considering these measurments you can use a standard power supply of whatever rating you want. It may be a little too tight between the power supply and the CD/DVD drive, but it is possible.

Good luck

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.

Dell C521 Power Issue


I would replace the power supply and if that does not help (after battery replacement and power supply), the ram could be faulty but usually faulty ram will beep a code. If ram has no avail i would suspect the mainboard and replace. Good Luck

Dell Dimension C521 power shuts off spontaneously seems the fan on the power supply isn't working.


Hello,

If the fan on your power supply is not turning then you need to replace the power supply as soon as possible. The machine is overheating and then shutting off. If the power supply is not replaced it can cause additional problems with the motherboard, cpu, and hard drive. Open your case and look on the power supply for your replacement parts number, check Ebay.com for a replacement. They are easy to replace, just a few screws and power plugs.

I hope this helps, if so please rate my solution.

Dell Demension C521. Dead! Nothing! Even the little led light on the motherboard.


This is most likely caused by a power supply failure. If you have or know someone who has another power supply you could use for testing thats where you'll want to start.

Hope this helps.
