One day I had very bad experience with my Caps Lock button. It suddenly got reverse function. Once I pressed it in ON condition, the alphabet became small letter. But when I Pressed it OFF, the letter became capital one. I was confused as I never had an experience like that before. So, as a solution I searched in the internet how to make it normal, function normally.
This is the answer I got.
Press both shift buttons together for some times. Then check it whether it function properly or not.
Thanks God my Caps Lock now is back.
