I just installed Lubuntu in dualboot with Win10 on a HP x2 tablet pc. I didn't have much trouble to install it, only had to disable the drive encryption on Win10 to resize the partition first.
But I'm having trouble with the battery. I keep getting notifications saying lxqt-powermanagement: no battery! I tried reinstalling that utility, I did a full update with Muon, I tried installing another battery monitor, and I checked that battery monitoring is enabled in both Lubuntu and the BIOS.
upower -d output below, while the unit is on battery:

Any help appreciated.
