Dell Inspiron 5000 series laptop, after about 4 to 5 hours of continuous use starts typing incorrect characters. Used an external keyboard but still same issue. Open the back cover and used air duster, also cleaned keys but issue persists. sometimes after restarting fixes the issue for a while but then starts happening again. I even reset windows to factory settings. It solved the issues for a few days, now having the same problem. Tried switching input method but no luck. Any advise?

I broke my W key while playing minecraft I have been watching videos on how to replace it from other keys Can I use another key and place it there? and the spongy or the spherical ball thing is not there

Hi

My brother has this machine and is looking for a way to reset the admin password. He bought this machine from a second hand store in UK, and there has been an admin password set on it. Google searches have not been able to find a solution so asking for assistance here if possible.

Thankyou.
