I bought my laptop in Jan 2017, its been only four months old. But, now my volume and brightness button is not working in the keyboard (i.e) function kry f2, f3, f6, f7, f8 and f9.
Please help me with this as soos as possible. I didnt install any apllications or any softwares. Just i am using for personal use like applying for job searching in internet and watching youtube.
