I've been using my MacBook Air last week just fine. Until I left it un-charged for 2 days (Over the weekend). This morning when I realised that I didn't charge it, I attempted to charge it. But I get no green light and my battery displays "Not Charging". I've had experience with bad chargers in the past with my MacBook Pro but this one is working fine. I've done everything the site has told me to do, including Resetting the SMC. I'm running out of options, anything I have not tried? As I need this Mac for my college work.
