Hai
find out if it is AT or ATX cabinet
AT cabinet will have a power ON/OFF switch just like a 2 way switch
ATX cabinet will have soft switch for ON/OFF
Mostly all the new cabinets are ATX type.
To make it sure, open the cover and check the power connector to the motherboard. If its a rectangular double layer connector, it is ATX power supply, on the other hand if its a two piece single layer connector, it is AT power supply
hope this information will solve your problem
good luck

Whining fan dell E520 computer


Replace the fan as soon as possible. If the noise suddenly stops, DON'T assume the problem corrected itself. More likely, the fan completely froze and stopped spinning entirely and you're at risk of overheating something inside. Generally, there are usually 3 fans in a desktop computer (cpu/heatsink, case, and power supply) and sometimes a 4th fan if the computer has a separate graphics card. Laptops usually only have one fan.

Dell Demension e520


These features are a functionality of the Processor used in the Desktop. These features are NOT a feature of the desktop itself and is limited to functionality of the CPU exclusively. Refer to this link for more information regarding NX, PAE and SSE2. http://windows.microsoft.com/en-us/windows-8/what-is-pae-nx-sse2

It is STRONGLY recommended you do not mess with these settings in the BIOS unless you REALLY know what you are doing.

99.9% of the time NOONE messes with these settings you should have no reason to do so.

Hi. I have a Dell Desktop dimentions e520.. 2 months ago, i went on a trip for a weekend and when i came back my pc wont turn on. it was blinking amber or orange. i search online and it might be the power...


The power supply is receiving power from the source but is unable to properly distribute it to the components. It sounds like the power supply but unless you have a power supply tester that indicates if all voltages are present the only way to make sure (and cheaper) is to replace the power supply as opposed to replacing the motherboard.

I HAVE A FLASHING AMBER LIGHT ON MY DIMENSION E520 DESKTOP


If you mean your Power Button LED is flashing amber then the power supply is receiving power from the source but is unable to properly distribute it to the components.This means that the power supply is receiving power from the AC outlet but is unable to distribute the needed voltages to the other circuitry of your computer. This can be caused bya defective power supply or a defective motherboard. Just to make sure thatnothing else is causing the problem, remove any PCI cards like modem, videocard, sound card, etc... Remove the memory modules and disconnect cables toCD/DVD and hard drives. Look at the USB ports to see if any are damaged.

No power on dell e520 dimension


On the 20 pin connector, short the green wire to any black wire with a paperclip. This will force the power supply to turn on manually if the motherboard is not giving the correct "ON" signal.

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.

No power to Dell demension 5100 desktop


If there is no activity whatsoever when you press the power button on than you have likely blown the internal power supply fuse. This will need a technician to repair.
