I have a 4yr old dell dimension 5100 that decided not to start today. i.e. no lights, no fans turning, no hard drive motion
-All of the power connections from the power supply have been checked
-All of the cable connections have been checked
-When plugged in, the LED on the motherboard lights up.
-The LED will not dim after unplugging and pressing the power button
-I have tried changing the 'power button' (part # X8682) with no result
help!
there are 4 lights on the back of the computer labled 1 2 3 4, check to see if they light up or not.
None.
it's possible that you have a bad power supply. you could test it with a power supply tester. you can get one for about $20 or less. just count the pins on the main connector on the motherboard to see if its a 20 pin or 24 pin connector.

or you could just replace it, but i recommend testing first to make sure thats the problem.
I'm going to try swapping powersupplies with my friend at school in January. If it's not the power supply I will probably just build a new one. Thanks for your help, I'll let you know how things go.
