I have an Inspiron 1150. I recently had it serviced for damage to the motherboard. That and a CPU fan were replaced. The note that came back with the system said that my battery was also defective and that I should contact someone at dell for information on replacing it. I've phoned customer care and tech support multiple times and I can't find anything. Would it still be under warranty (The laptop has a 1 year warranty) and who should I contact about it?
