Wires disconnected from power supply need wiring order


Theres no specific order for power supply wires. Just make sure it is disconnected from a power source and connect the Motherboard and optical drive cables to their respective plugs(plugs are standard for most motherboards).

Not turning on, has power and everything


Do any of the fans spin at all, as though it's attempting to boot up? If not, then double check your power supply to see if it has a switch on it and if it does then make sure it's switched into the ON position. If so, then I would recheck the power connector(s) to the motherboard. If those are well seated then I would start looking at the power switch itself. Those go out from time-to-time. Unfortunately, several eMachine desktops of this model type that I've personally worked on had faulty components on the motherboard; which resulted in having to replace the motherboard. The typical symptoms are that the fans spin and it tries to boot-up, but then nothing else happens: no POST beeps, no video - NOTHING. I have had some of them that just wouldn't show any signs of power\life. I've also had a few of this model type that just stopped working when the power supply went out. The likely cause of that is that the power supply will usually surge when it's dying out; which often results in burning out one or several motherboard components. Once you've reverified that all your cables are connected properly, but you still don't get power, find the 2 wires that connect to your power switch on the case (in your model it's usually the black & white twisted wires. Disconnect the connector, use a small flat-head screwdriver to touch the 2 pins that the connector was attached to. Be careful, there is electricity passing thru these 2 pins when touched together (jumpered), as well as the other pins if you accidentally touch the flat-head to another jumper pin. It should only take a second of jumping the 2 pins for it to start. If it still doesn't start this way, then I suggest replacing the motherboard. You can find good Micro-ATX motherboards on ebay for pretty cheap. If you still want to use your current processor, then make sure you get a motherboard with a CPU socket that's compatible with your CPU. I believe that your CPU is compatible with Socket 775.

Ok, test the power button pins. First disconnect any power source to the computer. Then, find the power pins on your motherboard (the one that your case's power button connects to. Usually two wires, one red and the other black). Grab a jumper a connect it to those two pins, they usually have the letters "pwr" or "power" printed next to them. Then, once you've done this, with the jumper connected, connect the power cord to your power supply. It should turn on by it self. If it does, then the problem is the power button. If it does not do it, then the problem is the motherboard. Good luck.

This is a motherboard problem. You'll need to replace it. Although, it may be cheaper just to buy a new PC (eMachines are never very expensive, or well-made for that matter)

Possible reasons are bad power switch, bad power supply, bad motherboard, bad memory , device card is not seated properly. Suggest replace power cord to see if still no power, also you may want to remove cover and make sure all your memory and device cards are seated corrrectly. If you get a amber light at the power button, bad motherboard is likely cause

Emachine T3624 desktop PC won't turn on?


I can guarantee 100% you have a bad motherboard. I have seen this exact problem with hundreds of E-machine PC's (especially your particular model).

What happend is the power supply went bad and took the motherboard with it, e-machines use very cheap OEM powersupplys that do not have any fault protection to protect the motherboard from damage if the power supply gets a surge or other damage.

You should not waste your money repairing the hardware in this PC, i would buy a new PC and transfer the data over.

Emachine 5210


Emachines used to use a poor quality power supply made by Bestec, I believe the quality is supposed to have improved in the last few years but inconsidering the number of dead Emachines that wind up in my workshop I doubt it.
The problem you have is that being a poor quality power supply there is a very high risk that it damaged the motherboard when it went out.
If you can borrow a power supply just to test with all the beter BUT be carefull some Emachines are proprietary and the main motherboard plug is not always wired in the standard way.
Check here for a replacement power supply if you can prove your motherboard to be OK.

Need wiring diagram for emachines t2200 motherboard


If you are replacing the power supply and it has 4 pin 12v conector and your motherboard doesn't, just disregard the 4 pin plug. The 20 pin conector will supply sufficient power for the processor. Many of the older motherboards did not have a separate 12v supply for the processor.
