ASUS laptop battery is not charging but windows says it is charging

Hi,

Windows says battery is plugged in and charging at 6% but it is actually not charging the battery.

I have had this issue since my laptop was shutdown due to the overheat while I was playing 3D game. After that happens, my battery does not seem to be charging. Is this simply battery damaged and time to replace?

I've used my laptop almost for 3 years now.
