Hi Im new to Mac. My son gave me his Macbook Pro a few months ago and I am still learning how to use it. So, if I ask something idiotic, its because Im an idiot still. ANd thank you for taking the time to teach me how to solve this problem. Here goes. My Mac is not charging. The first thing that went through my mind was that my charger (magsafe 85w) was shot. I had bought my OTHER son a brand new macpro so I plugged his BRAND NEW charger into my older notebook. His brand new charger didn't work either. So now, I figure its something with the book itself. A few days later, for sheets and giggles, I plug my old charger back in and PRESTO!! Its working again. So, may a long story short. Every few weeks, I can't get the charger to work and then it miraculously starts working again. I am now on day three on NON WORKING. I've cleaned the connections, that didn't help. I tried to reset the power by holding the power button down, nada. I even took it to an apple fix it guy and BOTH times, the charger that wasn't working STARTED TO WORK, so they said nothing was wrong. Any ideas?? Should I insist they open the machine up? ANY help would be great. The LAST thing I want to do is go to a hideous apple store in the mall. The fix it guys are located near me, so I don't mind going to them.....But I would love to be able to find the answer myself. Thanks everybody. I appreciate it very, very much.
