Laptop keyboard writes by itself - how can I stop this?

All of a sudden, the problem arose while playing. The cheat window was open, it wrote the symbol "-" by itself and writing made it impossible for me to play. I thought it was up to the game, restarted it and again the same problem. I then left the game and suddenly it also wrote in folders in the search window and the start in the search box. I stifled the laptop (because writing in the search window itself had the power button disappeared). When restarting, the problem starts anew with the password input. Several times laptop restarted, same again. I do not have access to my files to transfer them to a storage device. What can I do?

Your key is stuck. Take them out, that works well with a fingernail or pencil.

I've already tried that. Unfortunately without success.

Uff, so it's definitely up to your key. This is difficult with a laptop. Sry, if you pulled them out and maybe poked them around, I can't help you. There are certainly programs that can completely disable certain buttons. Look there.

I would recommend a round of CS: GO
After 5 minutes at the latest you have to hit the keyboard before aggression from the game and the button will no longer jam
