Batteries for laptops are alot like batteries for cars. They can just blank. For your laptop if you pull it out and plug it back in and still no effect than you need a new one. Take the thing out completely. If you can turn on the computer without it in than you still have a working computer.
If not proceed to step 3. There can be something wrong with the power supply module within the laptop itself (that is definitely not good) it would probably cost you just as much to replace it as it would to start saving for another laptop.
