Emachine won't power on??


from the video the only think i can think of is that some computers have a little red switch that changes from an american standard voltage to european standard make sure that switch is turned to 120v(located in the back of the computer with mouse and keyboard connectors). secondly the other solution if that didn't work the power supply were the plug is connected into for the computer is propably not connected to the motherboard. to do that their is a connector on the power supply that should say P1 that connects to the motherboard. if all that fails have some own or yourself plug something in to the outlet in which you use for your computer to see if the outlet is at fault. If all else fails get a new power supply and have yourself or a computer technician or have a pro technician in PC maintence look at your computer or just buy a new computer.

Hi Nicki,
Sorry, this really sounds bad, it would seem that the hard drive is shot from your description. The data may or may not be recoverable. If you get a new drive, you will have to partition it first, then set it as your Master drive, then set the old one as a slave, install your operating system onto the master drive and try to recover the information on the old drive after you have that done. If you cannot successfully recover the information that way, you most likely won't be able to get it at all unless you backed it up onto a flash or cds or dvds.
Sorry for the news but that is what it sounds like

Have a e machine fan runs but connect monitor to another computer it works. smell a burning smell when turn on pc. Got it to come up once by unplug power hold on button 45 seconds plug in and turn on came...


The smell is the Power Supply.

Typical example of a Power Supply not installed in a desktop computer,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4435072&CatId=106

[ NOTE*
This is not an example of a direct replacement Power Supply for your computer. I would need to know the Model Number of your eMachines to give exact information ]

Bad Power Supply. Weak voltage power rail. (Or rails. There are three main voltage power rails for a Power Supply used in an eMachines desktop computer)

Enough power to light LED lights, and apparently spin fans, but Not enough to turn the Processor on.

Watts = Voltage times Amperage.
One measurement used for measuring the maximum available power output, of a desktop Power Supply, (SMPS. Switched-Mode Power Supply), is to state the Maximum Wattage available.

Typical maximum Wattage available for a typical eMachines Power Supply, usually averages from 150 to 300Watts.

1) ALL of the LED lights on at one time, will use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use 51 to 125 Watts of power.
Depends on what Processor it is.

(Note* Intel Pentium II processors use less than 51 Watts)

Solution is to replace the Power Supply.
This isn't as hard as it 'sounds', if you have never performed this procedure before.
I know you can do it.

If you need guidance in replacing the Power Supply in a step by step for your eMachines, please post in a Comment. (Believe upper right of your page)

Should you also desire recommendations to compare for a Power Supply, I would be happy to provide them.

I have a T3626 emachine that I replaced the drive.


check all your ground screws on the motherboard. If that doesn't work try booting it up with out the hard drive. if that doesn't work, pop out the BIOS battery and unplug your computer, let it sit for about a min. and put the battery back in and restart.

Power Supply Problem


Hi, I came acroos a similar problem on an older model of emachine. If I remember it right what I did was to update the chipset and agp and other drivers (especially the lan card). The T5026 uses Intel 915GV. Most of what you probably would need can be found at http://downloadfinder.intel.com/scripts-df-external/Support_Intel.aspx?lang=eng. Most of the updates are chipset and OS specific. Good luck and please let me know how this works out for your. Cheers.
