    Same problem. I tested the old power supply and no response. The old supply does not light the green light whereas the new one does. Yet machine will not turn on. repair person stated that often with an e machine, both the power supply and the motherboard go. I'm not sure it is worth replacing the motherboard on this old of a machine. fremontdave@comcast.net

Have you try to test your power supply if it actually works? try 2 remove it from your pc plug the power chord on it and short the GREEN and BLACK wires using a pin or any conductor u can use. see if it turn on lights and fan turns on when you do that.

My t2862 powerlight will not come on but a green led comes on on the main board, nothing else happens. I also disconnected the pwr sw,hdd led and pwr led plugs and don't know which pins they go on. Thanks


On the front panel header where the wires connect, there are two rows of 5 pins. The top row actually has 4 pins with the end one missing, and the bottom row has 5 pins. The first two pins on the top row are for the power LED. The next two pins are for the power switch. The first two pins on the bottom row are for the hard drive LED, and the next two pins are for the reset button (if your machine has one). The LED connections are polarized, so if you get the connector backwards the LED won't light but it won't be damaged. Just turn the plug around and put it back onto the pins if your power light or drive light don't work.

Now, as to the computer not starting. Assuming the problem isn't due to the power switch not being connected correctly, you might have a power supply problem, or the motherboard has failed. Both are common troubles.

Here's a picture (from helpwithpcs.com) of the plug on the cable from the computer power supply to the main board:

This is the view from the end looking at the front of the plug. If you connect the pin marked PS_ON (it's a green wire) to the black ground wire on either side (not directly across), the power supply will turn on and its fan start running if it's working properly. If it doesn't start up, replace the power supply.

If the supply starts normally, your motherboard is likely to blame. You can search online for a replacement if you want to use the exact part. Don't try to get one from e-Machines; there many other sources. You can also use any motherboard that will fit into the case (micro-ATX style) and uses the same processor and memory.

T2862 wont work -no power goes to it.


emachine?
is it new?
if its not, then check the power supply, there should be a green light on the back of the unit. if this is yellow or not lit at all then the problem is your PSU

crack the case and make sure the PSU cables are connected properly
also while your in there check for swollen capacitors or dust

Nothing on my Emachines computer will turn on.


I would recommend rechecking your connection to the motherboard. All wires from the power supply to board and making sure the front panel switch connection are correct. Also, make sure the power supply is compatible to the motherboare. even though a 20-Pin ps will connect to a 24-Pin board, it still does not work. Good Luck

Can not find heat sink switches on motherboard emachine t2862


Heat sink switches? I have to assume that you're talking about a dead mother board but the fans and the LED on the mother board are OK? This is a classic eMachines problem. Their power supplies glitch and take out the mother board sometimes the power supply goes bad too.

E-machine will not power up even after replacing the power supply


If power does not come to hard disk, cd/dvd etc. then replace the mother board. And if you can put on the cpu and there is no display, then replace the RAM module.

EMachine T2824 does not turn on. Power cord/power supply seems O.K.


There are just too many eMachine models to be familiar with every one, however, as a preliminary inspection, remove the side panel, and turn the computer on to see if you see a green "Health" light. This will give you an initial clue as to how to pursue the problem. eMachines have historically had power supply problems. If you do not see a green health light on the motherboard, then your power supply is defective. A power supply supplies various voltages + - 5V, + - 12V ,etc. A power supply can be easily tested by a local shop with the proper test equipment. You might start there if you are a DIY! Short of that, you can purchase a power supply for under $65.00.

E machine no power


Make sure the RAM is seated, the CPU, any video card and the Power supply is properly connected.

If you power it on, still get no POST (beep at startup from the PC speakers) its time to replace the motherboard.
