On-screen keyboard pops up all the time?

Whenever I want to write, the part pops up. That's not my only problem. When I write a text, my notebook writes letters and spaces twice and that drives me crazy.

I turned off tablet mode in my device and turned off the on-screen keyboard too. Still it happens. I was hoping that it would somehow go away with the start tonight, but it's still there.

I haven't had this notebook long and you have to know that it just worked before, but one day after booting it suddenly was like this…

Can someone help me? I'm desperate. Writing this text was pure hell since I actually wrote it with my notebook.

Otherwise, I can only give the Google link

Unfortunately I can't help any more.

Ok, thanks in any case!
