Input problems on Linux 4.13 "^@"

Hello,

after updating the kernel to 4.13 I'm experiencing problems with the keyboard and touchpad of my Lenovo laptop.After the update, keyboard key repetition no longer works and touchpad response is sort of jittery / unreliable.  Any clue as to what might be the problem?

Please help

I didn't find the right solution from the internet.
