it can be two things, the motherboard can be fried or the power supply can be damage. what I would do is troubleshoot both devices with a known good device, the question you have to ask yourself first is: is my laptop still covered under warranty if it is let the manufacturer fix it because this void your warranty. If your not covered and you feel comfortable with doing the repair by yourself DO NOT ORDER PARTS FROM EBAY. I would go to Best Buy or whatever computer store that is close to you for parts.
