Question about Dell Dimension 5150 (DIM515MIN) PC Desktop

3 Answers

No power? The problem isn't mine! A friend asked me to look at his Dell Dimension 5150. It will not power up! The power button is flashing very slowly. When you cut the power, it continues flashing (possibly residual electricity) for 10 to 15 seconds. The unit was only new at Christmas!

    My Dell 5150 Desktop won't turn on, and the amber light continues to flash an amber color. After spending two hours on the phone, Dell says I need to replace the motherboard as well as the power supply unit. Any other suggestions on how I can just take the hard drive out of this unit and use it in another? I have a Dimension 9100, so I took the hard drive from the 5150 and put it in the new 9100, but it does NOT work? Any suggestions? Please help!

    I have exactly the same symptoms only when the pc has been powered off for a long time.
    As I suspected a temperature problem, I found out that the only way to get it working again was by warming up the motherboard and power supply with a blow dryer before powering on

I definitely think that this is a motherboard problem; however, I would first check the power supply to make sure that is OK. If the power supply is good you can try this workaround:

1) Disconnect all of the cables that are connected to the PC - Power cable, Monitor, Keyboard, Mouse, USB and any other cables.

2) Pull the small coin battery that is on the motherboard and leave it out. Wait for about 5 minutes.

3) With the coin battery still removed plug in the power cord. The power button will blink amber but at a faster rate. Give this about a minute and the power button will change to green and the machine will power on.

4) Once the machine is powered up replace the coin battery. Do not shut down the machine when you re-install the battery.

At this time you can connect all of the essential cables. You might need to press Ctrl-Alt-Del to re-start the machine once you have the essential cables installed.

If you power down the machine completely you might get the amber light again. I would plan on replacing the motherboard if you want to continue using the computer.

You can try simple step, unplug all the cable and press hold down the power button for 2 mins.This is called POWER DRAIN.Obiviously this will drain all the flea power and that may makes your computer to work better. But still if u have same problem,then i'm suspecting it may be issue with Motherboard or with Power Suppply. But if u want to try at your risk, you can open the tower and can reset the memory card, this should resolve the problem. If u want to know how to open the tower,you can visit the website

This i am sure is a motherboard fault, dells' tend to show this with the flashing power light, but obviously it's under guarantee so don't touch nothing, speak to Dell for a repair or replacement part.

Sounds like Faulty RAM modules, Open the box, and Try removing the Memory and re-inserting it, if that does not work, try one at a time and start the machine..**Make sure u close the Box before powering on. It could be bad Memory (RAM) module.

Most times when you have flashing yellow light there is issue ether with cpu or motherboard. Just to be safe test the power supply and if ok then try to replace cpu and go from there. If power supply issue just replace it. Might be easier to take it to pc repair store. Good Luck

If you experience the dreaded blinking orange power light, make sure to check your motherboard for blown capacitors as well as corrosion on the motherboard. Looks like the photo below.... if you see this then a replacement motherboard is needed.

Dell Dimension 5150 automatically turns off

That flashing amber light is usually a sign the power supply is failed or is failing. I would suspect the power supply is the problem in yours. It is the better of the two problems connected with the flashing amber light..the other is motherboard is failing. Arrrr!
hope this helps (it takes a standard- oh say 350 watt 20-24 pin power supply unit.)
Hope an answer helps.
