Dear atharvaidya,

 

Please try to:

 

1-press FN+F11, and check if it will work or not.

 

2-Install the Power Management .

 

https://download.lenovo.com/consumer/mobiles/2xem00ww.exe

 

Try it and feed us back please,

 

And please tell us if you are using the preloaded windows, or you installed windows from your own.

 

Regards,

Joseph

I installed the driver and the issue is fixed now. Thanks a lot!
And my Windows 8.1 wasn't preloaded. I installed it on my own.
