My MBA will no longer charge my iPhone while it is sleeping. Before I use to be able to open up my MB, plug in my phone, close it and my phone would continue charging. But it no longer does this! Now about 5 seconds after closing my lid my phone stops charging. I have been searching for a while over many different forums trying to find a solution but it seems like most people just say its not possible when I know for a fact that it is! When I first got my MBA I thought it was amazing that it had this feature and I would bring my MBA along with me while camping and use it as a charger for my phone. Considering I could get many full charges to my phone from my MBA's full charge. Thank you in advance for any info because this was one of my favorite features of my MBA!
