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.

I have an emachine model 3220. The bestec atx power supply has a part rattling round in it. Is it worth me buying a new power supply and if so other than bestec (as I have read bad reports on this item)...


When you say you have no power at all to your computer, have you checked the motherboard to see if you have a green light that comes on? You have to take the cover off and look at the motherboard. If the light does come on, it isn't your power supply. It is the motherboard. Good luck!

Emachine w2686 no display when boot up


Couple things to check. First, check with different monitor. Their monitors are usually build by KDS and I think there was a bad series out there. Also check for any beep codes through speakers on startup, this can tell you bad ram or bad video out. Also try unplugging computer and removing CMOS battery inside (watch like battery). Lastly, If non of the above, a bad processor will allow the computer to come on but no beep, no boot, no nothing but fans and green power light. Hope this helps a little.....

Emachine t3958


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.
