MacBook Air - Magsafe Light Stays Green, Battery Not Charging
I have a mid-2012 Macbook Air 11" that has developed a problem where sometimes the magsafe light stays green when plugged in and the battery does not charge. The status in the menu bar is "Power Source: Battery". Other times, usually after an SMC reset, the magsafe light turns orange but the status in the menu bar is "Battery is not charging".
Through copious amounts of googling, I've discovered and tried various remedies: SMC and NVRAM reset, unplugging the battery and draining the caps, even installing a new battery. None of these fixed the problem. My charger tested good and I was able to charge a friend's Macbook Air with it. Trying my friend's charger on my Macbook Air I experienced the same problem as described above.
My thought is that the the DC-in board could be damaged, but I don't know how to test the board. Is there any specific testing I could with a multimeter to check for voltages? Any damage that I should look for if I remove the board to inspect it? Could the problem be on the logic board?
Other than this issue, the computer runs perfectly, although the battery is draining a bit more each time I boot the computer, so I will soon not be able to boot.

Hi Dan, thank you for the reply. I was unable to install CoconutBattery because my battery is down to 1% so I had limited time to be able to take the attached screen shot. I did have a different battery health app installed previously and the details can be seen in the screen shot. I also added the Power screen from System Information. Note the negative Amperage indicating the battery is draining even though the charger is connected.

Did you use a metallic tool to disconnet the battery. If so maybe there was a short between the power pins (12v) and the data pins (3.4v) on the battery socket.
