You won't like this solution--your battery is bad or your motherboard is bad. If the battery does not charge, it could have acquired a "memory." That is, it sees itself full when it really isn't and it will run down very fast.
If the battery doesn't charge at all, it could be the motherboard. One other thing you could try is cleaning the contacts on both the battery and the computer. This may help--could be dirty contacts are preventing it from working correctly.
