My laptop doesn't go to sleep, how can I diagnose this?
My laptop doesn't go to sleep, how can I diagnose this?
It should be that if i close the laptop and leave it, even overnight, it should only lose maybe 5% battery, but it actually loses all of it, as if it was on (it gets maybe 5 hrs of battery life)
I have it set to sleep after 5 minutes. What sorts of logs should I check to diagnose the problem?
Fedora 41 KDE spin on a 6th gen lenovo x1 carbon (intel i5-8650U)
aside from this, i really am enjoying linux on my new toy
thank you all

I had that symptom, and I found that my laptop was using S2 idle (suspend to idle). I fixed it by switching to S3 sleep (suspend to RAM). I suggest following the instructions in section 3 in this page: https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate
Like many Arch Wiki guides, most of the information on that page is applicable to most Linux distros, not just Arch.
