E-Machines 2862 Dead On Power-Up

I have a problem with my daughters eMachines 2862 Desktop. Nothing happens when you press the power button on the front. The machine was working fine and then the next time she came to switch it on nothing happened, no fans no power light. I have installed a new replacement power supply, because I read that the eMachines P.S were prone to failure but it is still the same. There is a tiny green led that lights up on the motherboard when I plug the power cord in but thats it.

Can anyone help.

Thanks

    Hello there,

    Not sure if you made any headway into resolving your problem but I have the same issue on my T2862.

    PSU was dead not volateg on any connector not fans spinning. Put in a known good PSU (tested it externally by shorting green to black wire of 20 pin connector). All voltages were present and PSU fan spun. Inserted PSU into suspect Mobo and got green LED lit, only CPU fan spun immediately. Pressed power switch on CPU with no change. Measured voltage on the power cables going to CDROM and HDD. +12V measured ~+6V and 5V measured about +2.5V. My conclusion was PSU is loaded down some how. I also noticed that the rear fan tried to spin but my thoughts are since the 12V source it not nominal fan cannot start. I began removing all pluggable components off any power or cables (CDROM, HDD, DDR, Network Card and audio, Keyboard and Mouse). No significant change to voltage. Last part was the CPU itself. I removed this as well to no avail.

    I am now out of ideas other then try to find a new mobo (which identical ones are not being made anymore), or try to see if Bios set default could have been messed upto to prevent a PSU from coming up to what appears is a half the nominal voltages.

    If I get another mobo it will not be useable with my recovery disk since it is different then when made by emachine. These emchines have a bad wrap from what I read. However the mobo is an intel made design. The Bestec PSU that was in there seems perhaps at fault to start this bad chain of events.

    If anyone out there has had any luck with fixing the mobo I am all ears.

You might want to try to unplug it at the power cord and then plug it back in again,

I believe that the front button is not connecting to the switch for the power supply. Also make sure all internal connections are secure. Sometimes the button breaks from behind so that it cannot contact the switch. Let me know if it helps. There are other solutions if you tried this one first.

SOURCE: eMachine 2862 Desktop Dead On Power-Up

check all the leads to the hard drive and check that the fan starts spinning when you switch it on if it dont start then the problem is the switch these do often go and can be easily replaced and they are not expensive i had the same problem and found that it was just the switch hope this solves your problem for you you can bypass the swith so that the computer comes on when you turn the plug on but when you shut down the computer this shuts everything down but the switches are cheap enough to buy if you have changed the power pack then the only thing it can be is switch .................................

Hi there,

I would request you to check for the power calbe. Try and change the power cable and check if that works and make sure there is no continous beep on the machine as it would be a issue with RAM or hard drive.


Hope this helps you. I would request you to give a feedback on this solution as it would be appreciated.


Thank you.

I cannot boot up the computer. When I push the front power button, nothing happens. When I flip the switch on the back, or unplug it for 30 secs and plug it back in, the fan starts up and a yellow light...


I had this happen to my emachines T1842 about a year ago. I replaced the power supply and it worked fine. It was about 25 bucks but fixed my problem. Make sure the red switch on the back hasnt been messed with. it should be on 115. If you have moved it, it may have blown a fuse inside the power supply.

Emachine T3624 will not power up


Emachines are notorious for having faulty power supplies. If your lucky you just need to replace the power supply. I've seen a lot of them where the power supply also fried the motherboard.

Please don't forget to rate this solution.

E-Machine T2862 Will Not Power UP


I've the same problem, unfortunately, I disconnected the 3-plug connectors to the on/off switch, thinking they were a single plug. Now I don't know quite how to re-plug them.

The three color codes are black-white blue-white and red-white. I have the motherboard guide, but I would appreciate anyone's help reconnecting the 3-plug set correctly.
