I don't know why this is happening but this is a new battery.
Details of which are visible in the photo.
The problem is that even after the battery meter shows 100%, the power light on the laptop that indicates whether the laptop battery is being charged stays on. I kept it like that for a few mins to see if it would stop glowing, but it did not.
Has the circuit inside died ? What is the cause ?
