Dell India — battery issue and keyboard

Address:

Hi this is siva manjith. Here i am filling a complaint regarding the battery issue and keyboard problem of my laptop. I brought my laptop on january 18- 2018.
Since five month before i found that my number keys are not working properly especially the number eight, it is not working properly, and the hyphen symbol is too not working properly.
And one more thing is that my battery backup is very low. Even the 100% charge gives a work of maximum 2 hours.
