I am helping with a Dell Dimension 3000 with WinXP. Somebody put it into sleep mode and it hasn't come back on since. After this happened it spent a couple of months completely unplugged. From what I've learned reading other posts with this problem I've checked the following things:

- Whenever the computer is plugged in the green LED on the motherboard is lit.

- When the power button is depressed the fans spin momentarily, the power light lights up amber briefly.

- The green LED on the motherboard remains on throughout the power-up attempt.

- I've reseated the RAM and pushed on all the connectors I can see.

I think that unplugging the drives and removing component boards is next. Before I do that though I want to see if anyone thinks that putting the computer to sleep caused the problem and if there is a way of solving this without unplugging things.

 

Thank you.
