Gentry Morgan you have checked your power adapter to make sure that it is still working? you checked the DC port on your computer to make sure it looks okay and is not missing anything. What about the battery? Have you changed it yet? Does it still hold a charge when you disconnect the computer from the power adapter?

You need to measure the power on the connector end to see if you get the power there. After that traces it to see where it may be shorted etc. You have not told us if it works on battery power.
