You just got a free diagnosis, now you need it confirmed. You should go to an Apple Store or an Authorized Apple service shop.

Thuderbolt has no connection to the IO board and power feed, its on the other side of your Macbook Air The answer to that obvious, you should go research what the IO board is and does. Why would the IO board cause a problem with the AC adapter but not the Thunderbolt display? You can do as you like, reductive elimination is easy on the Air considering its contents and enough eliminative information given. and knowing the Air inside and out.Р В РІР‚СњР вЂ™Р’Вiagnosing the Air is rather easy, even without firsthand in shop diagnosis, it contains very few parts.

It has been my experience that the people working there have only the most basic understanding of how to fix anything, and even if they do, the cost is such a significant amount that it would simply be more cost-effective to buy a new computer. Please do not suggest that I take the computer to an Apple Store or an Authorized Apple service shop. Does anybody have any other suggestions, or is there anybody on the forum that actually understands the low-level functions of the SMC and how to make this work? I work on electronics for a living and have access to a lab with everything I would need to perform any kind of diagnostics or surgery on this computer.

I have noticed in my searching that this problem PLAGUES Mac computers of various types. I have searched the internet for any other SMC reset procedures and have found none. I do not think that there is a problem with my AC adapter, because various other computers will charge from it just fine, and my computer will charge from it under certain circumstances. My computer will charge from two different Thunderbolt displays. This is not a feasible long-term approach because I would like to keep the case closed. I can then connect to the AC adapter and reconnect the battery. So, to summarize, my computer will not charge from the AC adapter unless I disconnect the battery. My computer will not charge from any AC adapter unless I follow the procedure above. I have coworkers with MacBook Airs as well, and my AC adapter will charge every other Mac that I plug into it. I also have a Thunderbolt display in the office, and its power connecter will charge my computer every time.

If I disconnect the battery, then plug in the AC adapter, then plug the battery back in, then the battery will charge. The only way I can get the computer to charge from the AC adapter is to disconnect the battery. 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.
