Hi there,

I’ve recently noticed that my laptop (Intel N150 CPU, Fedora Atomic (Kinoite)) has several dips throughout a suspended state, as you can see on the picture.

cat /sys/power/mem_sleep prints [s2idle] sleep. Tried putting it to deep, but the laptop didn’t want to wake up after a minute, two or so, so I reverted it back to s2idle.

How can I find out and fix what is waking my machine? Something with journalctl maybe?

uname -a: Linux fedora 6.13.9-200.fc41.x86_64 #1 SMP PREEMPT_DYNAMIC Sat Mar 29 02:38:34 UTC 2025 x86_64 GNU/Linux.

Thanks,

Found the culprit elsewhere. Basically, if I have Wifi on when putting the computer to sleep, it wakes in the middle of its sleep and drains the battery. Stupid behaviour, can’t say where it comes from, but that’s the issue. Started putting it in airplane mode and the battery drain became stable and slow, like it should be.
