Question about Dell Dimension E510 PC Desktop

1 Answer

I have a dell E510 When I push the power button it blinks and the comupter does not come on. After about 10 minutes it stops blinking and is completely off. Push the power button, now it powers up fine. I suspect I need a new power supply.

Can't turn my computer on and i have a yellow blinking light on my dell dimension E510


Do you use a surge protector? If you do, try turning off the power supply to the surge protector and switch on again.
There are a number of causes for this problem, the most likely being a PSU problem or a motherboard fault/failure. To check the power from the PSU to the motherboard, you will need a multimeter to make sure enough power is going to the motherboard. Also check the motherboard closely to see if there is any signs of corrosion or blackened areas, which could be caused by overheating components. Check for leaky or burnt capacitors.

After a 10 hour power failure the computer did not power up. The power button blinks orange rapidly. I tried changing the cord and pulling out and replacing the button battery but there was no effect....


The Motherboard is defective. I hope it is still under warranty because these computers are notorious for corosion forming on the motherboard which ultimately leads to capacitor failure. Just open it up and check for any signs of corrosion on the capacitors on the MB.

Blinking amber light and wont boot up.


if the power button was blinking amber, unplug your tower, and hold the power button for 30 seconds to 1 minute, to use any excess power stored in the capassitors in the pc. this was told to me by a dell tech, it is a small issue with the 3100=E310, and 5150=E510 Dimension desktops

Computer seems totally dead


If the power cord is firmly plugged in - both ends, remove the battery. Does it turn on now? If so, replace battery.

Dell e510 won't make it to post


Unplug computer, disconnect all usb/monitor/internet, open it, hold power button until green led on the inside on the motherboard turns off, pop out the BIOS battery (looks like a big watch battery and use a small flathead screwdriver to depress the spring lock on one side), plug in computer, hold power button for about 20 seconds (must reset BIOS), let up on power button, wait 10 seconds and push power button. The computer should turn on. Wait for it until activity seems stable (1 min. or so). Push powerbutton to shut off.

If this has worked you have proven that it's not the power supply (it turned on). If you purchased a non dell power supply, you might try this with the original one installed.

Go buy a new battery (CR2032 3 volt). Unplug computer, open it, hold power button until green led on the inside on the motherboard turns off, pop in new battery, plug in (you should notice the power button blinking amber again), hold power button until it stops blinking (about 20 sec....again must reset BIOS), wait 10 sec., push power button. the computer should turn on. Wait for it until activity seems stabe (1 min. or so). Push powerbutton to shut off.

Now, close case, plug in all usb/monitor/internet/etc. Power up computer. You'll get an internal floppy drive error. Push F2 (maybe F1) to get into the BIOS settings and go to "drives" and turn off the internal floppy. Save and exit. The computer should boot properly now.

This seems to be a big problem with the e510, my theory is that this one small battery is the root of most of these failures (as these computers usually fail after 1-2 years), not the power supply or the motherboard (heck, when you replace the motherboard it comes with a new one of these batteries...a several hundred dollar piece of hardware, with a $5 battery that will actually fix it).
