100% CPU usage caused by upowerd

sx flag

On my Thinkpad (L490) notebook I have installed Ubuntu 22.04. Except for Docker it is basically the default setup of Ubuntu desktop.

Periodically I have a CPU utilization of all cores of 100%. Looking into top shows me, that the upowerd process has something to do with it. I am not sure how can I figure out what causes the problem and why.

My notebook is powered through USB-C by the monitor and I am using a Bluetooth keyboard and mouse.

I have read in other threads that an IPhone or IPad can cause these issues, but I am not using any of these devices.

Has someone a hint for me? Which logs can help to solve the problem?

Could you maybe include a screenshot of `top` or `htop` so we can see the same as you?

Are you running docker when the CPU usage hits 100% ?

By powering the laptop the way you do you are basically using it the same as an Iphone or Ipad. Have you tired the suggests you saw for the other devices?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
