 With kernel 6.6.9 when I put the laptop to sleep, syslog shows that the
 laptop was sleeping for 9h, fans were stopped, but when I gabbed my
 laptop it was warm and burned 80% of the battery overnight.

And yet, linux was not running, my logs show the kernel went into ACPI
sleep and back out

Logs show the system slept for 9h and went to sleep with s2idle.

Is it the wrong sleep outside of suspend to disk and full shutdown?

Are there devices that should have been powered off but didn't
(evidently yes since battery loss was 80% and laptop was warm)
