Keyboard not working properly on Windows 10

Suddenly laptop's keyboard started behaving weirdly, the top line of alphabets (q,w,e,r,t etc) is not working properly. Sometimes I have to press key many times to print a character , and sometimes I press it once and it prints letter 2 or 3 times, and shift + those buttons does not work some time. Please guide me is it hardware problem or software's fault

P.S: using Lenovo ideapad 300-15ISK windows 10

.(Pre-installed)

Thank you

Hello usman,

There is a very long LENOVO thread on this issue with a Lenovo 700 - 15ISK laptop. It looks to be a fundamental problem with the laptop.

One tip from the thread - try using with the battery removed - this seemed to eliminate the problem for many people. If it does not change anything for you, then you may have a different problem. If it is the same, then it is likely that a BIOS update will be required.
