Applet version/Build date
2024-07-04 19:20:18
Cinnamon version
6.2.9
Distribution
Linux Mint 22 Cinnamon
Graphics hardware and driver used
Intel Skylake GT2 [HD Graphics 520] vendor: Lenovo driver: i915 v: kernel
Applet name and maintainer
batterypower@joka42 @joka42
What happened?
Upon installing the applet and enabling, instead of showing the current charging rate or discharging rate when I unplug my laptop, the applet displays a yellow lightning bolt icon. Hovering the mouse over it shows the "Status unknown..." message.
Screenshot included in additional info.
Other information
Bit of a guess, but my suspicion is that the cause of this behavior is that this laptop model (Lenovo ThinkPad T470s, type 20JTS2BE00) features two separate batteries that are recognized as such both by Windows 11 and Linux Mint 22. Skimming through the code for the applet, and pardon my limited familiarity, it doesn't appear that the applet is designed to be able to process the presence of two BAT# folders from /sys/class/power_supply/ and combine the data collected.
Here's the info from the power_supply folder (screenshot included):
