Aux power led light is amber on dimension E521


I think your problem is your memory or video card.

Below are some steps that I recommend.

When you plug in the power cord is there any lights whatsoever on the computer?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the computer and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button.

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Maybe your power supply is bad. Sometimes there is enough power to make the power light or some other lights come on but not enough power to make the fan turn on or hard drive spin.


Below are links and info I found from Dell's Website based on your model.


http://support.dell.com/support/edocs/systems/dime521/en/SM_EN/specs.htm

Controls and Lights Front of computer:

Power button - push button

Power light
green light - Blinking green in sleep state; solid green for power-on state.
amber light - Blinking amber indicates a problem with the power supply inside the computer. If the system cannot boot and there is a solid amber light, this indicates a problem with the system board (see "Power Problems" in your Owner's Manual).

Diagnostic lights
four lights on the front panel (see Diagnostic Lights.)

Standby power light
AUX_PWR_LED on the system board

Hard-drive activity light
green light - When the computer is reading data from or writing data to the hard drive.

My Maxtor Onetouch 4 500gb external hard drive is not working, the light does not come on any more as if there is no power. When I tried a universal power cord the light blinks really fast, but my computer...


First thing you need to do is to confirm your Power supply is working, i think its a 12 volt adaptor so check wattage rating and then try to power a router or a device that uses the same voltage and wattage with it, an easier way is to check whether the light blinks once very fast right when you stick the adaptor into the external HD's back, if it does, download hyrens Boot CD from thepiratebay.org and burn it to CD...Most of the tools on Hyrens boot CD work in DOS but a limited amount works in windows, try booting into windows and try using the partition recovery tools like undelete etc, if this does not work you will have to take the actual HD out from the case by dissassembling it and then plug the actual HD without the case straight into your pc via sata cable, restart your pc and instead of booting windows boot the hyrens boot CD Menu, now use the partition and HD checking tools, this should work, if it does not, your HD is irreparably damaged and you might need to mail it to data recovery experts to get your original data back, Hope this helps..

Lights on, no display, doesn't boot


had similar problem on sony vaio. when power depressed, i could hear the cd drive turn a bit, the hard drive light blink once, and that's it. power light would remain on, but nothing else. I took it apart and resoldered all the main chasis grounds on the motherboard and shorted/resetted the board battery(memory/clock) and put everything back together and started up fine. got lucky i guess.

Can't boot up Dell 5100 Dimension, amber light flashes


When you mean the amber light, is that the blinking hard drive access light or the power light? Different cases have different colors on it. Mine has blue and green lights.

If you see the boot screen (bios) and then after it goes to boot, does it blink and hang?

This could be a simple operating system issue, hard drive or hardware/motherboard issue. If you could provide more information, that would help.

Not booting, blinking light


4 blinks, 1 second apart is a power supply overload. Have the power supply replaced if you haven't added any additional hardware lately. But also make sure your hard drive isn't bad and pulling an overload of power. it's rare, but I have seem that happen on some western digital hard drives.

Western Digital External Hard Drive Won't Boot Up


Take it our of the external encasing and plug it in directly to your motherboard. This has worked for me in the past. I just had my second wd external harddrive crash so now I will do the same process all over again.

Does the computer turn on all the way now or does it start to boot and then turn off?


Your Power Supply is no good, you are going to have to get it replaced. Once you get it replaced everything should be fine.
