I got the keyboard of my laptop replaced after this facing the problem
After turning on my laptop, on pressing any key, double key pressing appears automatically. Once removed with backspace, the same problem does not occur.
And once successfully logged in, keyboard testing shows repeated pressing of a key and some keys not working.
After restart and login again, the first key is fine and keyboard testing shows a different key being pressed repeatedly and some other keys not working.
Please request you to tell me how to solve my problem
Thanks
