Re: battery wont charge
If it works plugged in, but not plugged in you can be assured it is the battery. Batteries on laptops don't have a long shelf life and will only last about 2 years. You may just need a new battery. Usually you can purchase one through dell, or a third party vendor. If you are purchaing a new battery through another party make sure that it is rated for your laptop model (there are no 'univeral' batteries).
