I was on the chat with Dell for 2 1/2 hours. I am exhausted. The first tech got the supervisor who argued with me for an hour, at least. They are now saying that the warranty entitles me to in-home service, but they can't send a technician until they know the problem. Because it could be the LCD, video card, or the motherboard, and the technician has to know what it is before he comes out. You know because the laptop parts are so heavy that they couldn't possibly bring all three.
So, in the next two days someone will come fix this laptop. I'm not holding my breath.
