I"m not actually a Best Buy fan, but I had a laptop emergency and needed the Geek Squad. I shorted out my motherboard (long story) and after working on a huge project I hadn't saved my work. After a mini meltdown at the counter, the guy was able to start it back up and explained to me that it could go at any minute and that I shouldn't rely on it to save my stuff and to save everything externally. Very helpful actually.
