The keyboard does not work properly, how to fix it?

Question

Keyboard

The kids opened the lid of the laptop, they did something there, and now such heresy is happening
- When Caps Lock is on, it is off, and vice versa.
-Enter works like shift + enter, in the telegram messenger, pressing breaks the line, and does not send a message
- Combinations like ctrl + a etc. - also do not work (I did not try it with the shift pressed), however, the combinations on the task manager call work fine.
- LMB does not work properly. If you click on a link in the browser, it will open it in a new window, but not a tab, what would open in a new tab - RMB-open in a new tab.
-Mouse wheel doesn't work anywhere.
At the same time, the devils did not have access further than the lockscreen, tk. there is a biometric scanner, and a password of 26 characters in addition, and they still don’t know how to print, they don’t know how to read in Russian.
any ideas?

Answer 1

the shift is stuck in the pressed state,
tap both - it can turn off
