I am running Ubuntu 18.04.2 LTS on Surface 3. For some reason TLP can't see my laptop battery...

$ sudo tlp-stat -b
--- TLP 1.1 --------------------------------------------
+++ Battery Status
No batteries detected.*

Does anyone know why?

Unsupported hardware, the battery is missing a driver for Linux and you can expect Microsoft to not supply one

wiki.gnome.org has a run down on what does and does not work and the Bug report it refers to in regards to the battery. There are some patches in the bug report but nothing made it into the kernel yet.

On the lkml mailing list is a run down on the work Bastien Nocera did (same person who made the wiki.gnome.org link).

edit:

Maybe there is a way: there is a generic patch that includes Debian and Ubuntu. That will be your best bet.
