Hi, I closed the lid of my MacBook Air last night with about 60% charge. This morning it will not boot, and the lights on the MagSafe connector will not light. I have tried the SMC reset but the computer is completely dead. Does this sound like an IO board problem? Best regards Mark

Without being able to see it or know a history, there are two possible fixes. 1. You need a new charger or 2. You need a new MagSafe port. Those are best case scenarios. Worst case, your logic board is dead.
