Hello guys, I'm facing a weird problem with my Macbook Air/charger. Since I've been at home for most of my time in the past month, I've been using my Macbook plugged in most of the time. Still, sometimes I do unplug it and run it on battery only and then charge it back to 100% (I read somewhere that it was good for the battery). Anyway, today I decided to use my Macbook for a few hours before plugging it in, which I did when the battery was at 51%. As soon as I plugged it in, I was very surprised to notice that my Macbook Air wasn't charging. What's strange is that, if I click on the battery icon in the menu bar, it says (translated from Portuguese to English, these may not be the exact words in the English OS): So... it seems that the computer is getting power from the adapter, but it simply isn't charging. I've searched a bit and found this help article: http://support.apple.com/kb/HT3964 I tried to reset the SMC, by shutting the computer down, plugging it in, pressing Shift-Option-Control and the Power Button at the same time, releasing the keys and finally pressing the power button to turn on the computer. I'm not sure if I did it right, since I didn't notice anything and the problem isn't solved. Sure: my computer is still under warranty and I could take it to a store. BUT I'm afraid it would mean I'd be without my computer for a few weeks and I really need it (specially in two weeks when college starts). So, is there anything else I can try to do before taking it to warranty? I'm considering calling Apple Support since I have free access to Apple Support until October. Thanks!
