On Start, I receive a message: Warning: The battery cannot be identified. The system will be unable to charge this battery. Press any key to continue.

When I continue, everything seems to be ok; the battery charges normally. The warning appears on every Start. This started recently possibly after I installed Norton 360 Premier security package.

Can I continue ignoring it or does it really have a message for me. The laptop is an Inspiron 1501 and is slightly under 2 years old.
