para tentar resolver o problema vou começar por desativar a função de gestão de energia hybrid-sleep.target:
sudo systemctl mask hybrid-sleep.target

The key right of the "0" shifts boot device entries down in the list.

On the German keyboard this key is labelled with " ß ? \ ".

The next key on the right and left of the "Backward-Erase"-key, labelled with " ´ ` ",

pressed together with the Shift-key, moves list entries up.
