Greetings Community, my MacBook Air says that its battery is missing indicated by the x in the battery symbol. I reset it as I thought it would probably fix it. Now I’m stuck on lion as I can’t perform an update. When I want to, it says connect to the ac adapter, which it obviously is. Now my question, does anyone know how to bypass this, so I can update the macbook? And I won’t change the battery as I will buy a new laptop in a year for university. I plan on using the Macbook as a media center plugged into my TV. Thank you in advance.
Some how we need to get the battery working before you can do the upgrade. Lets give this a try to check your battery and the battery charging logic: CoconutBattery.
