Thanks.

Indeed, I now installed laptop-mode-tools and suddenly the 
HDA disappeared from the list of power consumers ..

I don't know *what* has changed in Debian/sid recently that this
not-saving became the default, but it happened, because I regularly
check with powertop and never saw the HDA before.

Anyway, thanks, back to normal.

Best wishes

Norbert
