E-Machine T2862 Will Not 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. It's not the power switch as I have I have removed the switch and connected the wires. Is there anything to reset, like a thermal overload or reset switch? I'm totally lost

Can anyone help.

Thanks

JWH

    Thanks Benimur but yes I did just short them momentarily, without success, so unfortunately the computer is still not working.

    I have the same pc and i think the mobo tanked!

  • Anonymous Mar 31, 2008

    the machine was making a lot of noise...not sure if it was fan type noice, or disk, cd/dvd spinning type noise...at any rate, the noise seemed louder than normal activity, so I shut the pc down (from the shut down on the win xp menu)...the next day, when we tried to power it up, nothing



    also, I disconnected the 3 leads from the front panel and now can't figure out where they plug in on that socket...anyone know which pair of connectors you plug those 3 leads in on?

    I am having the same exact problem. The old ps did not give me a green light on the mb, the new ps does, but nothing else. I chatted with emachine support but they were no help.

    '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.

    I resolved my problem by buying a $174 Dell slim desktop and and external IDE container.

    I found the jumper connections online, but it failed to help and it just wasn't worth the bother. I've just seen too many similar problems with the e-machine to warrant trying to fix the thing.

    I can't attach the html here, but e-machines support put me onto a web-page titled: D845GVSR_jumpers.html which showed the jumper connections.

    I got the same problem that I had been fixing for almost a year and a half.

    I'm considering getting a replacement motherboard for my eMachines T2862 desktop machine. Any suggestions?

  • onecandyx Apr 22, 2009

    My computer turned off one day by itself.the power butoon was still on but nothing was showing on the screen.I turned the machine off and it hasnt been able to turn back on since.I was told it is the motherboard but i dont belive it is.

  • kitkatr May 20, 2009

    I have the same problem where my daughter's T2862 does not power up. I have no technical skills with computers. The discussions posted seem to require some rather sohisticated skills (from my perspective). What can a no-skill person do to power our computer up? Thanks.

Regarding the power + power LED +HDD LED connections, if you haven't tossed the unit yet -- looking straight down with the box laying on side (e.g. CPU fan blades pointed straight at you) -- GreenWhite + BlackWhite (start with left pin, row nearest top of case) RedWhite (left two pins, row nearest bottom of case)

I have this same box doing nothing with new PSU, whether bare mobo or with components, and trying to short PWR pins manually. Oh well, emachines are basically disposable, much to the chagrin of Mother Earth...

It's probably the motherboard they are notoriously known to be weak. I've got myself into a situation where I have to replace one I will let you know what will slip into there with no case modification.

  • Larry Browning Feb 19, 2011

    Found a replacement at http://www.cputopia.com/emachines-mother... they don't rape you too badly $129. Also when I was inspecting the system the power supply HV transistors looked bad don't know what thats about so I replaced that for my client too (worth checking out before powering up) Hope that helps

The problem may possibly be one, (or more) of the capacitors on the board. Check to see if any are "buldging" on top. They should be flat but if any are "rounded", this is most likely the issue.

It seems from googling that eMachines are well known for this problem, the power supply goes out and when it does it takes the mobo with it. I've had 2 eMachines (one mine, one a friends) go out the same way.

Hi,

When you posted "It's not the power switch as I have I have removed the switch and connected the wires.", do you mean that you twisted the wire together? If yes, try just momentary touching them together. Most PC switches work on a push button momentary on system. Permanently joined together will not activate the PSU.

Otherwise, pls post back.

Good luck and kind regards.

    Hi again,

    Since there is a "tiny green led that lights up", we can safely assume that the power supply is OK. One of its features is to auto-shutdown in the event of a power related problem such as a high current demand by the motherboard, HD and other devices.

    Perhaps you can try removing all the power connectors to all devices except the motherboard (HD, CD, FDD) and try if the PC will power up. If it does, you can try plugging them back one by one and determine which causes power up failure. If not, it may be that you have a faulty motherboard.

    Another that you can check is the fan itself of the CPU. Verify that it can rotate freely and not stuck up. Some models will not go through the power up if the fan is not rotating.

    Incidentally your query as to a reset in your initial post, the only available reset on the motherboard is the CMOS/BIOS. It is a 3 pin/terminal with a jumper on 2 normally located very near the Lithium battery. Moving the jumper to the opposite pairing for a couple of seconds would reset the CMOS/BIOS of the motherboard to default. Thereafter, you need to move the jumper back to its original position.

The "solution" for me was moving the hdd to another unit I bought on ebay for $90...a dell optiplex with a ~3ghz p4 and a half a gig of memory...you can still use the xp os (you just need to go through the grief of working with ms support in india)

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 .................................

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.

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.
