My MacBook Air seems reluctant to take a charge , even though

This answer was rated:

My MacBook Air seems reluctant to take a charge , even though it is connected to a power supply. It is currently sitting at 65% of battery and gradually declining. Could I have some setting awry that is telling it not to recharge? Or is some other problem indicated?
Make sure you have all the Apple Updates... found under the Apple menu.

Reset your SMU;
-If the MacBook Air is on, turn it off.
-Connect the power adaptor to a working power source.
-On the MacBook Air keyboard, press (left) Shift-Control-Option along with the power button once.
--Note: You must use the keys on the left side of the MacBook Air keyboard.

Wait 5 seconds and press the power button to start the MacBook Air.
Apple recommends only performing an SMC reset when the MacBook Air has been properly shutdown. This prevents issues from occurring to the file system.
