[Pkg-utopia-maintainers] Bug#996131: upower shows all parameters of a battery as zeroes

[Andrej Shadura]

Package: upower
Version: 0.99.13-1
Severity: important

Hi,

After upgrading to the latest version of upower my laptop immediately
went to suspend despite the fully charged battery. Upon reconnecting
power and investigating, I learnt sleepd forced it into sleep because 0%
battery.

Indeed, this was what I was getting:
