video Fix the Dell OLOD (Orange Light Of Death)
If you have a Dell pc that won't turn on, Chances are that you have a power supply problem. Most of the time the power light will be flashing
Orange.

Step By Step:
(Disconnect all cables, Inc the power)
1. Open the case of your Dell Pc
2. On the power supply box (top right) find the GREEN wire
(The green wire will almost always be the power switch on all Pc's)
3. Cut it at around the middle
4. Strip Both Ends
5.Find a long enough piece of wire that will reach to the front of the pc
6. Solder the GREEN wires back together but putting your seperate peice of wire inbetween them
7. Tidy them up with zip ties and shrink tubing (Electrical Tape if not)
8. Plug the power cable into the pc
9. Hold the wire onto the chassis of the pc
10. If the fans start at full speed, press the power button and let the wire off
11. your pc should be running as normal.

If I understand you correctly, the problem is that when you turn on the Dell PC the power button is illuminated AMBER and the power supply fan runs at high speed, and the computer will not boot.

There is an easier fix for this problem: Unplug the power cord from the back of the PC. Press and HOLD the power button on the PC while you plug the power cord into the back of the PC.

I am an IT specialist in a facility with approximately 1200 Dell Optiplex PCs. I have "fixed" a number of these computers with this same problem.

gdaily1, I tried your soloution on my Dell Optiplex 745 and it didn't work. Anything else I should try?

Does NOT work on either board. On board 1 no fan turn. On board 2 fan TRIES to turn, cannot break magnet pull. Rotating by hand does NOT help. Is this a sign that the boards are BAD? Cannot return them as they are used and the seller will not accept them. He stated they came from working towers. PLEASE RESPOND with more fixes. reeltoreelguy@gmail.com

DELL mobo 4H665. Will NOT power up with only the power switch, fan, and PSU connected. GREEN led on power board 1 does NOT light, on #2 ORANGE blinking. Fan does not turn on either. Will this trick work on this board. There is NO GREEN wire in the 24 pin connector. Only ONE PURPLE wire. Is that the same as the GREEN?
You are SO awesome! I tried it and it worked! Oh my gosh! Usually it's some terrible news, but it worked! Thanks!
Wow. Had this very problem and followed this easy procedure. It worked!!!! Thanks so much. I was freaking out. I never respond in forums btw. That's how happy I am that this worked.
Sometimes at my school, we have had dell computers that don't turn on at all because the USB was shorted so it was a simple fix just to lever the bent pins off the USB shell and then the PC's started as normal ;) (BTW I'm only 13 and have fixed many computers at my school)

the fans do not work at all when you press the power button! nothing happens... the fans only come on when i forcibly add power to the Power Unit and then press the power button to make it turn on

hello,
I have followed the steps you shared but after 9, I make the green wire "extension" to touch the PC chassis and the fan turns on and then after pressing the power button the fan stops and the blinking light appears again... any other advice?
btw thanks so much for sharing this solution steps!

I had the same issue with my OPTIPLEX 745... instead of cutting and soldering, i held a lighter to the green wire, melted the plastic a bit, then scraped it off to expose the wire, wrapped another wire around the exposed green wire, followed your instructions, and it worked for me as well. i am on it now and so happy, I wanted to post feedback. It did actually take about 3 power on and off cycles, but I have now shut down and restarted a few times successfully. Thanx for the post!! ( I used electrical tape to cover the exposed green wire when done)

You are telling us that these Dell machines have a faulty power-on button?
Why not just replace the button?

curtisg890 (author)  lemonie3 years ago
Because its not the button thats the problem, its the power supply or the motherboard

You are not doing anything to fix the power supply or the motherboard (and you aren't even sure which one you think it is...).
Connecting a wire to GND is a switching operation, that's very most likely exactly what the power-on button is supposed to do, isn't it?

i'm not trying to fix them, i dont particually want to either. i just found this method to bypass the problem.

yeah thats probibly what it does but i dont know that much about newer computers, only about the older ones which are much simpler to work on. i wouldnt know where to start if i was actually trying to properly repair it :P

I'm similar, I've got just one surface-mounted transistor screw-drivered on a really nice Gigabyte board - whole thing is 'ked...

The power-on button runs THROUGH THE MOTHERBOARD, to the supply...

This informative, if kludgy, hack bypasses the motherboards power-on fault issue.
Turning it into a direct-power switch, similar to old AT power supplies.

One thing to watch out for... after a few weeks to months of running this way, the failing capacitor on the motherboard(the most likely cause of the original problem) may let out the magic smoke. At that point, a re-cap job will be needed. Consequently, the grounding wire to case will no longer be required.

i has been like that for around 2/3 months so far, i made the video because i had to replace the switch.

I have a Dell notebook and since the batterie is broken its flashing yellow... Dont know how to fix it without changing the batterie, which I dont really need.
there is no way to fix that without tearing the battery apart, removing the eeprom, reprogramming it and then replacing the battery cells...

Its a safety feature that only allows a certain number of charges before it disables the battery from ever working again.
