nouvau eating battery

I use an external monitor on a wayland sway setup, with nvidia/amd  hybrid card so i had to use nouveau for external monitor.

But I had to disable the power management for the card, because otherwise  my monitor never wakes up from sleep. ( nouveau.runpm=0 in grub params ) , but this is making my laptop wake up after suspend and ate up all the battery overnight. Any solution here ?

Re: nouvau eating battery

What if you unplug the external ouptut before the S3?

Edit: also

cat /proc/acpi/wakeup

Have you tried linux-lts for this issue ? I am facing similar issue, which gets solved with linux-lts. https://bbs.archlinux.org/viewtopic.php?id=280215
