No Batteries Available.

[SpecialEd]

I installed Kubuntu 18.04 on my new-to-me Acer and my Battery/Brightness widget is showing "No Batteries Available." but there is obviously a battery installed. A sealed one at that. I didn't find anything searching the forum.

In the repository is an app titled “acer-firmware”, or something like that.

Do you know which repository? I didn't find it in Discover/Synaptic/Muon

First I added the battery widget to the taskbar but this morning while cruising through the system settings looking for something totally unrelated I clicked on the driver manager. It recommended a more recent Nvidia driver than the one I was using. When I changed that and rebooted, I got the old widget back.

apt search acer | grep -i firmware

and

apt search firmware | grep -i firmware

both come up empty on Kubuntu 18.04 for me.

NVidia related ... Interesting!

When I went searching for that "acer firmware" I realized that it was actually an acer kernel mod that I used.
acer_wmi.
Also, there is wmi, wmi_bmof, and acerhdf
Modinfo gives the dope on them.
The acerhdf was interesting:
