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. However, if I disconnect the AC adapter, it will not charge the battery after I re-connect it. 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.
