I’m quite puzzled by the following message when clicking on the battery.
Under Power Profile it says:
Performance may be reduced because the computer is running too hot.
I’ve tried searching for the error message but did not find anything.
I’ve also tried to check the cpu temperature, but didn’t notice anything out of the ordinary.
- How can I investigate why this message is displayed?
- How can I check whether performance is actually reduced?
- I run Kubuntu on a Dell 5750
The message comes from the power profiles daemon library, and gets displayed in response to signals from the device’s firmware. The detection for this condition is out of KDE’s hands, I’m afraid.
Thanks for the fast reply. Do you have an idea in “whose hands” it might be so I can investigate there? Are you suggesting it’s the “power profiles daemon library”?
Not to speak for Nate, but if you Google/Brave Search/etc. “power profiles daemon running too hot Ubuntu” one of the top links is this bug, which is still open in Canonical’s bug-tracking system and seems to be exactly what you’re experiencing (even if the person reporting was seeing it in the GNOME equivalent view, it’s been identified as connecting back to the same underlying power-profiles-daemon component).
Wow, thanks this seems exactly like my problem. I’ll have a deeper look!
Hopefully there’s something helpful there - one general tip I found during my time running Kubuntu, since the underlying distribution is Ubuntu, most core system functionality (especially things like hardware control/drivers) will be shared - so even if you can’t find a resource that is specific to the Kubuntu flavor, Ubuntu forums and tips will be just as relevant for that stuff.
(i.e. things like hardware performance/power management on Kubuntu will be more similar to Ubuntu’s base GNOME flavor than they would be to openSUSE running KDE, because for that stuff the role of the desktop environment is mainly to present graphical displays and controls of what the underlying system components are managing)
Yeah, so it’s not actually even a power-profiles-daemon issue. PPD simply passes along the information it gets from the firmware to us.
Ultimately the problem (if it is a problem) is in the device firmware itself that comes from the hardware manufacturer. They’re the ones who determine the conditions for what counts as “too hot,” how much movement triggers the “I might be on your lap” detection, and so on.
