How to solve "Brain not working" or "Battery not getting charged"?

1. Try to switch on your brain by connecting the charger only (without battery).




2.  Connect the battery to the brain and then plug in to the charger. If the LED turns red, it means this is charging. If not, then check the connection between battery & brain.


3. Check the pin of the battery. If the pin of the battery is not straight or bent in another direction, then the issue is with the battery only.
