Thanks Diana. I went to PC Mobile/IT Headquarters where both Kevin and Barb were very friendly and helpful. Since my Macbook Pro is a late 2008 computer, Apple wouldn’t work on it, and The Mac Store wanted $49 for a diagnostic fee, plus $129 to fix the problem; and it would take 7-10 days. Kevin fixed the problem and I had my computer back in less than 3 hours; and he only charged me for the $20 part, and no labor fee. I would highly recommend using PC Mobile.
