The green light of DEATH :-(

--------------------------------------------------------------------------------

I plug the power cord into the computer, and the power buttons light up, i press it, and nothing... not the slightest sound. On the inside, there is one LED light that lights up, and other than that there is no sign of life. The computer doesnt do anything. No beeps, no sound no nothing, just the power light and the LED light in the computer, its a dell. What do I do to get this thing to atleast boot? please help me, I got told if i fix it i can have it... an id like to fix it if i could
the powersupply uses a foxconn ribon, the computer is an dell optiplex 260... if that helps.... theres is a foxconn ribon connecting the motherboard to a chip that has a headphone jack, two usb ports, then from that chip there is another foxconn ribon that connect to the the chip that contains the 2 LED lights, and the power button

Check first if the motherboard does not have bulging capacitors.

Do you have a spare power supply? Try that one also to isolate the problem.

Try also pulling the cmos battery out for 1 hr, and clean it with cloth and put it back again.

Try to clean the contact of your memory stick and your pci vga card (if any) with a pencil eraser and reseat it several times into the slot. Try one stick at a time. Then start.

Post what will happen.

I have taken the power box out of the computer, and ran another computer with it, also i have used another computers power box in this one and all that happens is the green light shows up. on the LED and the switch light. I took the switch out, wired it and it would turn off and on another computer. There is a fox conn ribon going from the mother board to a chip with 2 usb slots, and an headphone jack, and another fox conn ribon that connects to the power switch, could it possibly b the chip that the usb and headphone jacks are connected to?

Your computer internal wirings may have already been tampered. I just sent you some pictures and informations about your computer. You can trace the connections through the color coding. Study them well.

Check all attachments found at the bottom.

This happens to me often, and these are the steps I use to fix the problem:

1. Clear CMOS, remove battery and reverse jumper to short board
Place battery back in cradle and set jumper to normal position.
2. I usually check CPU to ensure it is seated properly
3. Ensure power switch are seated on proper power pins (laugh! I've made the mistake before)

This will usually correct the problem, if not your CPU could be bad or mobo, or in some cases both :(

First try a known working PSU in this PC. Pull your CMOS battery for some time.

if these two things do not work, you have a bad MOBO or CPU. Thats all there is to it.

bad psu, almost always the culprit

[ebarrera]

you must have a bad mobo, or cpu. if the psu worked in another pc than we know its ok. i doubt anything got miswired, because there is not much to plugging a psu into a mobo, the cpu fan should at least come on.

so in closing, if the psu works in another machine, but not in this one, then you got a bad mobo
