When I first started using lxde on my hp laptop, the only way I could get a readout of battery charge was via cli...sorry I don't remember the command. Later tonight I will fire up that computer and add details.
Anyway, after an update a month or two ago, I was happy to see that batti allowed me to check battery status from the panel at the bottom of the screen.
I fired up that computer yesterday and applied all updates.
Now batti and the cli command always show zero battery charge even when fully charged.
