Last year I purchased a used Dell XPS M170 laptop on eBay. I checked with Dell before bidding to ensure that the warranty was still valid and that the system had not been reported stolen. I was told the extended warranty was transferable to me. Soon after I received the laptop, Dell replaced the power brick for me. Today I requested replacement of the cooling fan, but the representative I spoke to said he couldn't help until a hold on the account was resolved. Dell had placed a hold on all computers handled by a service technician who had requested re­placements for laptops and then sold the laptops instead of returning them to Dell. My XPS was one of those, so Dell now refuses to honor my warranty. Can you help?
