If everything is working properly, then yes, those lights are normal. Many motherboards have LEDs on them to show standby power. You probably didn't notice them until you worked on the thing.

I have an Abit IC7-G motherboard. Machine has died with no reaction from pressing power on and reset buttons. Power cable in is OK and when connected, green light behind IDE1 socket lights up (which says...


Most obvious problem would be the power supply. The green LED only indicates that the 5V rails os working enough to power the on/off circuit on the motherboard. First disconnect everything except the mother board from power supply. Then try switching on again. If this does not work, then disconnect the power connectors from the motherboard. ON the big power connector (P1) there should be a green wire with two black wires either side. This is the power on sensor wire. Use a paper clip or similar bit if wire to short out the green wire with one of the black wires. This should start the power supply and the fan in the PSU should spin. If this does not work then the PSU is definately faulty. If it switches on when there is no load connected then it is probably only slightly faulty (not able to provide sufficient current). Since the green LED is coming on, my guess is that you have bad capacitors in the PSU (they will probably have domed tops instead of flat). Try a power supply from another PC if possible.

Green lights...no power. HELP!


This could be a problem with your power supply. If the motherboard sees that the voltages from your power supply are low, it will turn itself back off.

You can test your power supply by unplugging all of your internal power cables, ground out the green wire on the 20-pin/24-pin ATX connector and check your yellow (12v), red (5v) and orange (3.3v) wires. If the voltages come back more than 10-15% off, you will most likely need a new power supply.
Even if you have good voltages using the test method above, it is only an indication that your voltages are good at zero load. Your power supply may still fail under normal load. If you have recently added any hardware to your computer, remove it and try again. If this still doesn't work or you haven't added any hardware recently, replace your power supply.

Wont start


If you see the red LED then the Power supply is ok. Sounds like there is an issue with the Motherboard, Either a cable got disconnected, or a bad board.

Power supply


I think your problem is not with the power supply, its the hdd or memory thats causing the problem. try to check the cables, and re insert the memory then start up your pc again.

Emachines t3882 wont power on


The yellow wire carry 12 volt while the red one is 5 volt. But to check the voltage you have to unplugged all the four wires connectors (yelow, black, black red) and measure them one by one. If you say that they don't have any voltage on them then you have a faulty power supply. Replace it to solve the problem.
But if during unplugged your have the correct voltage read then it could be one of your device faulty. Normally your CD-ROM drive or floppy drive or HDD.

Foxconn motherboard red light and nothing else


Remove all connectors and cards except vga and power supply. and one stick of memory and start there.
If its still an issue remove the board from the case , it may be shorting out on something and try it outside the case,
check the power supply switch for 110/220v switch on back if it has it.
to manually trigger the power supply on the 24 pin connector
short the green and black wire that is next to it.

Power LED on but no boot up


it could be your power switch, veriy that it isnt the power supply by

1.) un-plug it from the main board
2.) look at the main board connector(one coming of the power supply)
3.) you should see green wire and next to it a black one
4.) using a paper clip bridge the too wires
5.) if it works proceed to net step if not get a new power supply

to check case switch and board switch

1.) plug in power supply to main board
2.) look at the pins where the power button connects to
3.) using a metal object (blade screw driver) bridge the pins

if the board should start up>
then its your power button on the case that is bad, you can try to repair it, chage it or buy a new case,

if it doesnt work.
1.) ensure that jcms(jumper to flash the bios) is set correctly
2.) unjack each drive one at a time to see if any is causing stalling
3.) get a new main board

Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.
