I have Ubuntu 20.04 running on a Fujitsu Lifebook s761 with two batteries. Both batteries are detected but only the main one is charged. Previously, Windows was running on the laptop and the second battery worked as intended and was charged.

Does anyone have an idea why the battery is not charging and a suggestion on how to solve the problem?

Thanks in advance, toni

Ubuntu does not charge any batteries. That is done by the hardware. Maybe trying re wording your question so it does apply to the OS.

That is correct. I updated the description of the problem. Thanks.

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.
