Laptop gets hot but CPU and GPU utilisation stats show near-zero usage

zm flag

Until recently my laptop under Ubuntu wasn't even starting fan. Now, while idle it makes quite a lot of noise and feels hot under the keyboard. I have i7-1165G7 and Mesa Intel® Xe Graphics (TGL GT2). I checked htop and intel_gpu_top and both show cpu/gpu utilisation under 1%. I checked the system monitor, no signs of CPU load too. The laptop is 4 months old, and shouldn't have a lot of dust, still vacuumed just in case.

Any ideas on how to approach this situation? Thanks in advance.

Hardware problem?

If this is a dual boot laptop, check if the same thing happens with Windows. Also boot from a Live Ubuntu installation USB using the **Try Ubuntu** option, and see if the same thing happens. If it happens with a live USB, it is probably a hardware problem. Contact the manufacturer for replacement of service under warranty.

I have a similar problem and not yet solved it. I don't have hard stats to back it up and can't even remember now which Ubuntu version caused the issue but I have Conky running and I know that older versions of Ubuntu my CPU/cores/ACPI temps were always below 60c at idle. After an Ubuntu upgrade with no other changes I noticed higher temps straight away. Today with 22.04.1 LTS all temps are fairly constantly 60-70c at idle with no apps running. No high cpu/mem usage.

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.
