Keyboard and touchpad
Keyboard and touchpad respond only on the login screen (I can type only my password). After log in, only power button is ok. Wireless mouse responds. Can I solve it myself? Thank you!
MacBook Air 13″, macOS 10.13

Hi,
Start up in Safe mode then normal boot could solve the issue.
Start up your Mac in safe mode - Apple Support
If it doesn't help, try to run Apple Diagnostics if it's a hardware related issue. Error codes are NDK001, NDK003, and NDK004 for keyboard, and NDR001, NDR003 to NDR006 for touchpad.
