Comment 17 for bug 1589383

This issue was here since a clean install. I've tested with latest 4.7.0rc2 kernel and the issue exists. Battery info is not available. The first comment contains the solution from ArchWiki, which needs to build my own kernel. I haven't test it myself on the tablet, though. The bios config has nothing associated with battery, acpi or i2c, so I didn't try to modify it.
