I was wondering if I could get some ideas from the wider Mac community... All of a sudden, my MBA won't charge from the magsafe adaptor any more. I've tested it with my brother's magsafe and it doesn't charge from that either, although it works fine with his MBP. I've done an Apple Hardware Test which came back with no faults found and I've reset the SMC with no results. It has not suffered any physical damage and does not get used that much. It even still has that lovely 'new mac' smell lingering about it. It's still got about 25% charge left in it and I have given up tinkering with it for now. I want to leave some juice in it for when I go to the Genius Bar tomorrow. Before I go there tomorrow, I'm just wondering if anyone has any ideas of what might be wrong? Thanks.
