I have this laptop that won't power on, so I figure the battery must be dead, but when I plug the AC adapter strange thing happens, if I plug the AC adapter in the power outlet a green light comes up on the AC adapter, but as soon as I plug the AC adapter into the laptop, that light shuts off. What can be the problem

a new development, I found a docking station and it powers on fine on it, I will try with a battery out like you said, to see what happens.

same thing happens with the battery out, the light on AC adapter is on until I plug it into the laptop, then it goes off.

Try the power adapters on another laptop. I suspect they are both bad.

I'd get a universal power supply like this and you can use on any laptop to test - http://www.amazon.com/Rocketfish-RF-BPRAC3-Universal-Laptop-Adapter/dp/B002ZVHFEG/ref=pd_cp_e_2

that won't work, this power supply connector is a larger round and has pins inside!

If it works on a docking station and has a special port on the bottom for it, then it's very possible the AC port on the laptop is bad. I've seen the connector inside become unhooked from the PCB before because of heat over time.
