Hi gokulms,

Thanks for posting.

Here is some information for troubleshooting battery issues.

Batteries are considered consumable items and are not usually covered past the warranty period.  You can obtain them from several places:

1. Dell Spare Parts

2. Discount Electronics

3. Parts-People.com

Please steer clear of Chinese knock offs because they have allegedly caused fires.

Let me know if you need further assistance.  Thanks.

Regards,
Robert
