HP Recommended
Product: Elitebook 745 G3

Since some time built-in keyboard is behaving strangely:

1) With Fast boot enabled it is impossible to enter boot menu nor BIOS setup with neither built-in nor USB connected keyboard

2) With Fast boot disabled USB keyboard is recognized but with the built-in keyboard laptop:

 - reacts to Esc/F9/F10 keys but not accepting any* keys after that

- continues to ignore any* key presses while in GRUB screen

- starts to accept key presses once the OS starts loading (no matter Windows or Linux)

* Exception is Ctrl-Alt-Del sequence which is still working fine during boot up process. Also caps-lock and num-lock LEDs react normally.

Tried already to replace the keyboard but the issue is still there. Tried also to downgrade BIOS by one version with the same result.
