Power problem on 5100

One of my kids powered off my Dell 5100 at the mains and it now ont power on. The green LED is lit on the motherboard. I followed the troubleshooting on the Del web site to no avail, so I suspect that the power off damaged the power supply - can you help

    I have a similiar problem. I push the power button and nothing happpens but sometime in the next 3 minutes to 3 days the computer will power up on it's own. I replaced the power supply, the power cord and the cmos battery. Same problem. I followed the Dell trouble shooting of removing all components one by one, then trying to power up but no change.

    Sounds familiar. Replaced surge protector strip and power supply cord to computer. Still unable to power up. Green light on motherboard works. Just a little over 3 years old and out of warranty.

    Same as the other two - out of warranty 6 weeks ago, stopped working after 2 power cuts in the house. Did all the Dell fault analysis, the Dell technician says it's the motherboard needs eplacing! She didn't mention the power supply of surge strip (where is that?). Looking at a big bill frm Dell to return and repair.

Has anyone solved the not starting issue for dell 5100?


I had the same problem and it turned out to be the Front I/O & Control Panel Assembly. I suspect that the USB ports had shorted out and took the whole card down. The not turning on problem was preceded by the USB ports failing. I couldn't figure out how to bypass the card to power the computer. Dell won't help if you are not under warranty (unless you purchase some additional support). I couldn't find a replacement board on Dell's web site but found some other vendors that sold them. I bought one for about $70 and it did the trick. There seems to be at least two similar model numbers for this card. I don't know if they are interchangeable or what the differences are. If you look on the card there should be a series of numbers. Look for an "X" followed by 4 numbers. In my case it was "X8682". This is the model number for the card. If you search for shopping sites with your Dell model and this card number you should find vendors to buy the card. I think this is a design flaw having the USB ports on the same connection as the on switch. It looks like many people have had this problem. One bad usb port and your whole system is taken down. My guess is that the average user is not going to be able to figure this out and will spend lots of money unnecessarily. For those comfortable opening up the case and covers (you can download the manual from the Dell site) and unplugging ribbon cables this is a fairly simple fix. Keep in mind the card won't come with any instructions. Make sure you follow power safety rules and ground yourself.

When powering on the fans spin and yet I get no video. The LED under the PSU (CR9E1) flashes. What is the LED indicating?


This indicates power supply failure. PSU means Power Supply Unit.

Solution?
Replace the power supply.
MAKE SURE it is a compatible one!

What do I mean by that statement? In some years of Dell manufacturing, Dell made their computers "Proprietary".
This means only Dell parts could be used in a Dell computer.

The wires in the 20/24-pin ATX main (Motherboard) power cable, were put in different socket holes, than a standard 20/24-pin main power cable.
Yellow is 12 volts. Orange is 3.3 volts. Red is 5 volts. Black wires are Ground wires.

If an aftermarket power supply made by another manufacturer, were to be used in these type of computers, it will burn out the motherboard! Possibly the ram memory and processor also!

If you buy an aftermarket power supply, instead of a Dell unit, make SURE the colors of the wires are in the same place, as they are in the Dell 20/24-pin main power cable connector!

For more info about that last statement, I suggest you check out this page,

Dell dimension power supply / motherboard


you may consider reseating the P1 and P2 cables (from the power supply) connected to the motherboard.


you can go to www.support.dell.com and enter the service tag of your dell system (found at the back of your system) and look for the manual on how to add/remove the parts of the computer.

thanks.

Dell Dimension 9100 will not power up


Most likely the power supply have failed. Although the system is getting some power to the Motherboard (Flea power indication on motherboard) there are at least 5 different voltages the power supply provides for the system. Losing any one can cause a no power situation like you describe.

A standard ATX power supply should resolve (It is the 1st item I'd replace, both because it is the 1st point of failure and the cheapest to replace)

Here is one ATX power supply:
