A question about udevadm trigger for power-switch

vu flag

I use ubuntu 20.04. Today my computer shut down automatically twice. I entered 'journalctl' for checking and got the result 'systemd-logind[761]: Power key pressed.' I googled this result and found out that it's triggered by the power button on the physical device (Similar issue). However, when I entered the code mentioned in the content for checking, I found out some device that are not related to the power button. Is that normal?

udevadm trigger -v -n -g power-switch | xargs -i cat {}/../name

Has the power button gone bad? Is the computer over heating?

Power button have nothing wrong. I wasn't install sensors before, so i don't know if that is question of over heating. Maybe that is the question what is happening. thank you.

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.
