Dear Thorsten!

Thank you for your quick response!

Now that you gave me the advice to check dmesg I found out that the
messages are the same with kernel version 5.16.10 and 5.16.12. But - as
I described - with kernel version 5.16.10 I had to press the power
button to resume from suspend. So I my conclusion that my laptop does
not go to suspend ist apparently wrong. In any case you find excerpts
from dmesg with both kernel versions attached.

Now there is one thing I really would like to understand. Concluding
from the time stamps in dmesg it seems that my laptop goes to suspend
only for a moment right before I re-open the lid. Of course I did not
close my laptop lid only for 3 seconds - as it could be concluded from
the time stamps for "PM: suspend entry (s2idle)" and "PM: suspend exit"
- but for a longer period of time. Can you please enlighten me about
that?


Thank you and best regards,

Reinhold
