My hard drive got screwed up (again, for the 2nd time) and I got a replacement shipped to me. Now I took it to the local repair shop, and I got a bill for $150. As they were repairing it, my grandmother (who got me my Dell) said that the warranty covered the installation as well. Now, I'm confused. I looked at the Dell website and found nothing but technical terms that made no sense to me. Did she make a mistake? I have a Dell Inspiron 1545, with the three year extended warranty with Limited Technical Support and Rapid Response Depot. Also, I know my battery isn't covered by the warranty. But It's toast, and my dad said that there are some knock-off batteries that are 'compatible' with Dell computers that we can get for cheaper. The business said they have been doing business for years, making computer parts for a fraction of the cost. Should I trust and pay $30 for a warrantied knock-off battery?
