Best buy is also the company that told my wife her laptop was completely dead and there was nothing they could do to fix it (this is after charging her to take a look at it), when the only problem with it was the monitor cable had come loose.
See what I mean Growled. They are not exactly the people you to hold up as a paradigm of knowledge. They often don't know their ass from a hole in the ground.
In fact back in the day they wouldn't hire me after I corrected a Geek Squad manager who was talking about a PC that was in there. He said it had to be some sort of custom one-off custom built PC that they wouldn't know how to fix.
It simply had a BTX motherboard in it...which while rare isn't any different to work on than an ATX board for the most part. I pointed that out and he was ****ed that I knew something he didn't. That interview ended quickly.
