    I am having the same problem lately after I used a blower to blow away all the dusts cumulated inside the machine. When I got it inside and power connected, push the off/on button. Nothing happened ... the PC looks dead. The green light on the board is green but that's all to it. I bought a new power supply but did not help. I may also messed up the location of the power wires which would not help.

    Could someone have knowledge about the wiring diagram although I am not very hopeful that it is the problem.

    crayzeetrayn I have the same prob with the same model PC. I tried your troubleshooting tip by unhooking all the devices except those on the motherboard. No fans spun up. No sounds. Just the same little light on the motherboard. Does this mean the board is toast? Or is there something else to try? p.s. - I also bought a new power supply and did the cleaning/dusting out thing...

    I also have a T2893.  Wouldn't turn on, nothing, no fans, no noise.  Had power supply checked, they said it was bad.  Bought a new one and installed it.  Still no response.

    The green light only indicates that the motherboard is getting power. Now when you say you turn it on and nothing happens, what exactly do you mean? it just does not come on? or you get a beep error code? or nothing shows on the screen?, do you hear your hard drives spinning up?.......... in either case, here is a question for you, has anyone installed any new hardware in your system? If so, it is possible that they could have disconnected the wire between your switch and the motherboard.

It sould be as simple as the on/off switch being bad .. the power supply could be bad .. it is powering the 'led' enough but it is faulty and cannot power the machine.

Try disconnecting all the components .. cd, hard drives, floppy ,etc .. but leave the power plugs on the motherboard .. try ...see if the CPU fan or power supply fan spin up..

Not turn on and lights a green light on motherboard

E-Machines were known to have Power Supplies that went bad for no apparent reason, the worst part was on some of the computers it also did killed the motherboard, you can pickup a power supply tester at most computer shops for less than $20.00, or you can choose to get a new power supply.
I have found Ebay to be a good source for a replacement

I accidently removed 3 sets of jumpers (power, LEDS for hard drive) when removing the front panel of my E-machine T2893, and cannot remember which jumper goes to which set of double prongs on the mother...

On the motherboard the pinouts on the front panel should be colour coded, and marked with letters like in this picture >>>>>

The connectors are also marked corresponding to where the connect on the motherboard, like in this picture >>>>>>

If the board is not colour coded then the motherboard will marked with the same letters, you may need a strong light to see the marks.

Does the T2893 have to have an ATX power supply specifically for the emachine? I tried to upgrade to logisys 480w supply and the fans and a few lights come on, but the unit won't boot up.

there are TWO different power cables on the new machines. (not just two parts to the ATX)

one is the ATX like you are used to.

The other is a small four-prong plug (coming off of the power supply - look for yellow and black wires) find the matching receptacle on the motherboard.

good luck

Machine wont turn on at all motherboard is receving power

Could be but unless there was some sort of power surge it would be pretty rare for a motherboard to just randomly short out, although you may want to dust out your PC as I have seen really dirty PC's sometime not want to start up. But more details would help.

Same problem - green "power" LED on the MB but no activity


This series of machines is known for this issue. You can get a replacement motherboard for your pc from a website at they boards run from $35 to about $65 plus shipping. This is much cheaper than you can get them most other places. We order from them on a regular basis and have had no problems. I hope this helps, if so please rate the solution.

No boot, New PS, Green light on MB lights, No Fans running

Bottom line: Either your power supply or (hopefully not) the mother board has gone bad.
Replace power supply (remove old one), take to local independent computer shop, ask them for new unit. Should be around $50.00. - no more. After reinstall, if still no fans, boot, etc. Replace motherboard or buy a new machine. MB's installed probably will run you around $250.00-ish.
Good luck.

T2893 e machines wont turn on

Since you are looking inside, try this. Trace the wires that come from the power switch back to the Motherboard. The wires from the switch will connect to two pins on the motherboard. Carefully jump those two pins with a screwdriver and the machine should turn on. I would suggest doing this with all drives and cards unplugged first.
