Question is up…
I have had the problem for a few weeks that my laptop keyboard only works after about 10 minutes and it has not worked at all for 2 days.
Since the laptop is relatively new, I can't really imagine that the keyboard is broken.
Yes, there seems to be a defect. You have a guarantee, so go to the dealer and complain.
I have an "app" on the laptop manufacturer and it tells me that everything is fine… I'll wait and see what others comment on.
