Macbook air 2015 battery recall4/13/2023 Today, at the office, I have taken the computer apart again, and tried both SMC reset procedures again. It would, however charge from my Thunderbolt display. Then, I took the computer home, and it would no longer charge from the AC adapter. This worked, and I could operate from battery, or plug in the AC adapter to charge the battery. Apple does not want users opening the case to their products, but I already had the case open to replace the battery, so I tried the alternate procedure of disconnecting the AC adapter and the battery, and holding down the power button for 5 seconds to reset the SMC. The reset procedure for the MacBook Air is supposed to be the CTRL-Shift-Option + Power button, however this did not work for me. So, I found suggestions to reset the SMC, which I did. It seems that Apple has had this problem in various forms going back at least seven years. After searching this forum, I found that many, many users of practically all types of Mac laptops have similar problems. If I disconnected the battery, then the computer would power from the AC adapter. Once the new battery was installed, the computer would operate from battery, but would not recognize the AC adapter and charge the battery. I have a mid-2011 MacBook Air, and I recently replaced the battery.
