I installed Ubuntu 18.10 on a fresh new Lenovo Ideapad 330-15ICH, and I have issues with the battery. The battery indicator does not appear in the status bar, and acpi -V shows:

Adapter 0: off-line
Cooling 0: Processor 0 of 10
Cooling 1: Processor 0 of 10
Cooling 2: Processor 0 of 10
Cooling 3: Processor 0 of 10
Cooling 4: x86_pkg_temp no state information available
Cooling 5: Processor 0 of 10
Cooling 6: Processor 0 of 10
Cooling 7: Processor 0 of 10
Cooling 8: intel_powerclamp no state information available
Cooling 9: pch_cannonlake no state information available
Cooling 10: Processor 0 of 10
Cooling 11: iwlwifi no state information available

(note that the adapter was plugged in when I ran this).

Here is dmesg | grep -i battery:

[ 7.543690] battery: ACPI: Battery Slot [BAT0] (battery absent)

The battery is most certainly there (it's internal and non-removable). BIOS is configures as EFI, in non-secure boot mode, but I see nothing concerning power management.

There's a bunch of ACPI stuff at dmesg, which I will post if anyone deems them useful. I see people mentioning a bunch of other issues but not this, so I'm guessing I'm doing something wrong.
