Have you tried live CDs of other operating systems to see if this is a

Title:
xfce power manager shows wrong battery life information (Lbuntu
16.04.3)
Status in upower package in Ubuntu:
Incomplete
Bug description:
As per title xfce power manager (version 1.4.4-4ubuntu2) on my Lubuntu
16.04.3 shows a wrong battery life. What happens is that I plug in the
laptop, it tells me the battery is 100% I unplug the write and I can
see after maybe 10 minutes that the battery level lowered.
I check and it gives me something like 80% and then, suddenly the
laptop turns of because the battery is discharged.
When i plug it back it shows as the battery is either charging
correctly or charging and the percentage is over 70%.
The battery is a few months old, so I think the problem lies in xfce
power manager which displays the wrong information.Bug #1216594 opened
in 2013 is very similar to my case, however that bug report was closed
not because it was fixed but because it expired after 60 days.
I tried 'upower -d' and it gives me the same info as the power manager.
