Chosen Solution
The battery on my Macbook Air is not charging, even though the power cord is connected. The LED is unlit on the MagSafe connector. Trying different outlets and a spare power adaptor made no difference. The battery indicator in the Status Menu Bar shows the power source is the power adaptor and the battery is not charging.
However, the battery system preference says it is charging when the power adaptor is connected.
If I unplug the power adaptor, it shows this.
I replaced the battery and and it still didn’t charge, even after resetting the SMC several times. As long as the power adaptor is connected the battery level currently remains steady at 47%. Next, I replaced the I/O board, which other posts suggested might be the culprit, and still no go. I did reset the SMC again several times after the I/O board replacement. Any ideas on what the issue might be and next steps?
Inspect your MagSafe cord for damage like:
Also inspect the pins
As well as the systems contacts and the insulator area make sure both are clean
Use some isopropyl alcohol and cotton swabs (Q-Tips) to clean both. You may need a fresh pink pencil eraser to polish the contacts Did that fix things? If not you’ll need to inspect your connections focus on the I/O board MacBook Air 11" Early 2014 I/O Board Replacement you may need to replace it if the contacts look burnt like this one
