Macbook Air shows power is plugged when the charger is not plugged in.
My Macbook Air keeps on showing the plugged in symbol (looks like battery with charger cable) on the battery even though I am not charging my laptop. When I plug my charger in, it will take a few seconds just for the power(thunder) symbol will shows up. When I will remove my charger, it will also take few seconds before the thunder symbol vanish then it will go back to the plugged in symbol, which is the battery with a cable symbol. It doesn't go back to the normal battery symbol when I unplug it. What am I supposed to do?
This is the status when I charge it:
