Describe the bug

The error message below happened. Right before the timestamps of the logs, the computer showed 0% battery and then shutdown due to critically-low battery.

• OS: Linux Mint
• Version: Latest?
• Configuration file: default
• Installation method: installer script

Additional context
Crashes in a tool which controls system temperature are very bad.

In my opinion, this tool should be marked as Unstable in the README, based on this experience.

Hi there, if I understand correctly, the programme got an error before your pc ran out of battery?
If so, could you provide the full logs?

Also, in the event of a crash or the service being stopped or paused, the original temperature controller takes over to avoid any hardware damage.

I also have issues with false battery reporting. I have no idea where it comes from. I wrote about it a few days ago here: https://community.frame.work/t/responded-battery-percentage-gets-misreported-as-0-occasionally/38056/19

What makes you think ectool is the culprit ?
fw-fanctrl is indeed making a recurrent call to ectool battery. But I don't think that this call has any effect on the state of your OS (what's your distribution btw ?)

[leopoldhub]

Hi, as other members are encountering this problem without the use of ectool https://community.frame.work/t/responded-battery-percentage-gets-misreported-as-0-occasionally/38056/19 (post on Framework community forum by @TamtamHero ),
I assume that this is not specific to our project and will close the issue.

I hope it will be fixed soon.
Have a nice day.
