My work laptop had a faulty mousepad so went to several big chain stores looking for a solution. The best they could offer was three weeks without my computer while they sent it around the country to their real “techexperts” and charged me $120 (just to have a look). Unable to be without my computer for so long I went to PC Patch. They fixed the problem on the spot. That’s the benefit of going to a place with experts rather than salespeople in-house.
