because you have just plugged it in it checks if it is a charger
When an iPad says that it is not charging, it simply must mean;YOUR iPAD IS NOT CHARGING!Silly numpty head! x
this actually happened to me too either you take out the battery and let it sit out for about 6 hours or you replace the battery.
did you mean to ask what to do if your laptop battery is not charging? if that is the case http://laptop-battery-not-charging.com/ might be able to help you.
Problem with the charging system.
It means it's time for a new battery.
A battery that is only at 50% is not a good battery unless it just needs charging.
it means it still charging, when fully charged that will turn into a cord plug
alternator is not charging battery, or loose - corroded connection on battery cables
You have a problem with the charging system.
Alternator is not charging the battery
The alternator is not charging or not charging enough.
it means you need to charge it and fast or your battery will be SHOT!
