If your computer allows it, try running on just AC power (remove the battery). If it works, then you know its the battery, if not, then you may have other problems. Here is a site with some steps to follow to help determine your specific problem. This is another useful website for battery troubleshooting.
Hmm... well, one last thing you can try before you have to send it in (if you have a warranty on the computer, I would just recommend sending it in) is to go and buy a new battery. If your computer still cannot turn on, then you have a power fault somewhere inside the laptop itself. I would definitely bring it to someone who is qualified to fix the problem, unless you still have a warranty on it. You may even be able to take back the new power cord, because I'm betting that it wasn't the cord in the first place.
