Hello Soccermike,
I understand that your computer will not boot.
Do a hard reset.
Turn the computer off.
Remove the power cable and the battery.
Hold down the power button for 15 sec while booth power sources are removed.
This should reset the hardware in the computer.
Also try to boot without the battery connected.
If you have tried other adapters it may be a problem with the board.
Make sure that the wire for the adapter is not loose.
Try to just wiggle the wire for the adapter inside the computer.
Let me know how everything goes.
