As soon as the power cord is plugged in the fan stats running. The green light in the front comes on. It doesn't boot up. The keyboard is not responding either. The mouse works. If I shut it down for awhile the fan doesn't start as soon as it gets pwer and the pc boots up normally and everything works fine, but only for about 20-30 minutes or so. The the same problem occurs. Any advice? Thanks!

Re: E Machine T2682 powers up but, doesn't work
This sounds like an overheating problem, that is why the fan comes on right away. When you let it rest, it cools off, and works normally for a while.
Most modern PC's are designed to slow down their operating frequency when they over-heat, and if that is not enough they will go into suspend, hibernation or (totally off) modes to protect themselves from permanent damage.
Solutions: Bigger power supply, more and better cooling fans, improved space and airflow around the cabinet, cool the room with aircond.
also better heat-sinks on the CPU and/or the chip-sets.

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 .................................
When the computer is off, unplug the power cord from the laptop and then plug it back in. See if the charge light (lightning bolt symbol next to the led) comes on or turns green/blue. If it doesn't your power supply may not be working, even if the light on the supply is on. Second is the battery may be damaged. Remove the battery and see if you can power on at all.
If it boots with only the cord, the battery is bad/shorted forcing shutdown.
Ok what do you mean by doesn’t work? No power? no lights? dead? Have you tried a different power cord? I ask this because of these things
Laptop power cords can just give out without warning
And just because the green light on the power cord is lit does not mean it is putting out enough power or any at all
And even if you test the power cord and it reads the correct voltage does not mean it is still putting out enough amperage to handle a load (like powering up the computer) Of course that is extremely rare but I have seen that happen before
Before giving up hope I would try borrowing another cord from someone with an HP laptop or one of those I-GO laptop cords with the changeable tips or something or even better yet try your power cord on a different laptop and if the other laptop turns on .then well I am sorry
NOTE: if your power cord has a little green light on it and that light goes dim or starts flashing as soon as you plug it into the laptop then that is a very good indication (9 times out of 10) that your motherboard has gone bad and shorted out somewhere.
But there are too many possibilities of what could be wrong with out more info
When you plug it in do any lights on the computer come on at all?
I wouldn’t give up all hope yet .. that is a pretty nice little computer and worth trying to figure it out.
Track down the motherboard manual, the motherboards of branded machines are usually made for them by PCChips or Foxconn or someone similar.
In the manual identify wich connectors on the motherbaord is the front power switch. Disconnect the front power switch and plug it all abck in again to see what happens with the power switch disconnected.
If you feel brave enough you can momentarily short the motherboard powerswitch connectors and the machine will start.
the front power switch is a momentary switch so only short the motherboard pins long enough for the machine to start.
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.
