It's hard to troubleshoot a power supply. They are very dangerous and contain electricity for some time after turned off. If your new one isn't solving your problem it makes me think it's not the power supply unless it's not powerful enough. Try this:
Open your case having your "CPU & HEATSINK" in sight. You can lay your case on its side if its easier to see this. Power up watching only the cpu fan located on or in the attached device over your processor (cpu). If it doesn't turn then that is likely your problem. CPU is overheating which automatically shuts down system. Pls. make sure both 20-24 pin and 4 pin plugs from power supply are tightly plugged in mother board before you start.
If it is working try another power outlet in your house. Sounds odd but is a known issue.
Could be a few more things but these are most common.
Let me know pls. your results.

Emachine won't start .power is on, fan is on, doesn't boot up


I love this one. I've actually done this many times before and have been successful.

1. Turn the computer off and unplug the power cord from the back of the tower.

2. Press and hold the power button for about 3 seconds while the computer2_bing.gif is unplugged (this drains the remaining power from the capacitors on the motherboard2_bing.gif).

3. Plug the computer back in and turn it on.

If that does not work, follow steps 1 and 2 again, but this time:

3. Open the computer while it is unplugged and unplug the power supply from the motherboard then hold down the power button again for 3 seconds. (You may also want to take the RAM out and put in back in)

4. Plug everything back in and turn the computer on.

When you say out, do you mean they are broken, or just disconnected? Most of these computers have a plug on the end of the wires to the front panel and it just plugs into the system board. If you look at the board you'll see where the front panel wires go. Sometimes it's hard to read the small type, but there are labels on the board that tell you what connector does what.

Emachine flashing yellow lights, fans power up when P8 is unplugged


Did some research and found this site which will tell you which pins to test. It is possible also that its not powerful enough for the devices you have. I would try again only giving power to the motherboard pins, of coarse and the hard drive. If works then plug one device at a time.
Good luck

First check to see if a drive died. Unplug all the drive Floppy, hard and dvd or burns. I have come across many time that a drive will die and keep motherboard from booting. Being that you say you get a green light on the motherboard shows that the power suppy is providing some power. But for some reason the internal self test is faulting the power suppy. I have not come cross any bad power supplies killing a motherboard. But I have come across power supplies killing drives. The power switch is a normal open switch so the only time you be able test continuity on it is if you hold the switch in, or the closed position.

Emachine T2484 will not power up


Try to start it without any memory in it (RAM), if it beeps then you have bad RAM. If you have more than 1 piece of RAM then try one at a time and see if it will boot. If it doesn't beep and still doesn't turn on your CPU is probably the culprit since you have a new motherboard and power supply. I would also try unplugging everything that is unnecessary like the CD-ROM, Hard drive, sound card, etc..

Emachine help


Hi. could be a few things
1st thing if theres no power going to the base unit, the power supply is gone will cost about £20 for a new one.
2nd thing it could be graphics card, memory needs refitting. ie take them out and refitting them usually fixes it.
theres a few other things it could be but less likely. i suggest trying the above..

have a great new year
