Battery charge not updating, always whatever it was at startup

After installing 22.10 on a new laptop, the battery charge (indicator) never changes. It is charging just fine though, but upower shows the wrong value.

$ upower -i /org/freedesktop/UPower/devices/battery_BAT1

and

$ busctl call --system org.freedesktop.UPower /org/freedesktop/UPower/devices/battery_BAT1 org.freedesktop.UPower.Device Refresh
Call failed: Method Refresh is not implemented on interface org.freedesktop.UPower.Device

I guess that error is why it does not update.

UPower client version 0.99.20 
UPower daemon version 0.99.20

(I have seen reports that downgrading to 0.99.17 could help, however I have not been able to try that, because of the many dependency issues)

Restarting using sudo systemctl restart upower.service does not update the value, only after a complete reboot it shows the correct value.

UPDATE Turns out that power for the wireless mouse was not working either. And acpi did not update, including the temp sensor, which seems a bit dangerous. Solution:

Installed 22.04 again and now it all works as it should.

To be clear Upower is not updating but the battery is charging? What does it say in the OS about power under settings?

David , yes. It is annoying, because when unplugged, it shuts down unexpectedly after about 6hours, while still showing 100% :) Under settings it shows the same value (not updating) . Nothing in `/sys/class/power_supply/BAT1/*` seems to update after (un)plugging the cable.

For upower you may want to ask the upower people. For the OS maybe file a bug report. https://ubuntu.com/blog/the-keys-to-successful-bug-reporting

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.
