Computer problems and the time and expense of resolving them is something I have a very low tolerance for. Truong, your ability to quickly analyze and inexpensively repair our computers is greatly appreciated. Your recent repair of my laptop that I plugged into a 240 volt outlet on our overseas trip is a case in point. The geek squad’s analysis fee was $75 and their repair estimate was $150 to $350. In one trip to our home you repaired the laptop for much less than what would have cost with the Geek Squad. Thank you!
