This device appeared in my power settings after installing ubuntu 18.04.4. I have no idea what it is. I am getting annoying 'low battery' alerts and I would like to get rid of this device from that list. I would assume that it's an Elantech device. Maybe the touchpad? Has anyone ever experience this before?

I am running the 5.0.0-25-generic kernel on an Asus Q526FA with an Intel 8th Gen i7.

It's an Elan Fingerprint reader. You should be able to disable it with TLP.

  • My computer doesn’t have a fingerprint reader. Is that still something that would be recognized by Linux? – ghood97 Aug 23 '19 at 23:36

Asus probably has a very similar model which does have a fingerprint reader, and uses the same motherboard for both. That's why you see it.
