Address:

New Delhi, Delhi, 110015

Hi,
I purchased a dell laptop with below details-

Amazon order number: #[protected]
Dell vostro 3468 14-inch laptop (7th gen core i3 - 7100u/4gb/1tb/ubuntu
Serial no. - 91718f2

When i purchased dell gave me 1 year + 3 months extended warranty. After using it for few months i started facing issue with its key pad and touch pad. While typing keys cursor sometimes move to above lines or below to the current line. Keys are not being pressed properly.
Talking about mousepad it gets pushed down and does not come up back on press for left and right click. Also pre-installed ubuntu 16 speed is ery slow i am not sure is it due to os or the hard ware.
But, it was not that frequent.
But now once the warranty is over this issue in recurring and persistent.

In crust i have below issues:-
1:- key pad and touch pad while typing
2:- slow hard ware
3:- slow pre-installed ubuntu operating system

I need help in this with a request to
1:- change a mouse and key pad in free of cost
Or
2:- repair these hard wares
Or
3:- provide new machine
