I know this probably a bit of a n00b question, but I am trying to figure out how to monitor my laptop’s power state over time. I have tried
powertop, but either I am not grasping how to use it for my use case, or it is not the right tool.
My main concern at the moment is the following: even if I manually send the laptop into suspension, the LED around the power button remains on. This has started since I upgraded to 22.10. While on 22.04, the LED would start pulsating slowly. How do I figure out whether the change has to do with a change in behavior of the LED or if something in the power management got borked?
