[Pkg-utopia-maintainers] Bug#601345: Debian Bug #601345: wrong battery charge level

[Akira Kitada]

I'm hitting the same issue. (Debian Sid)
You can see the dump is showing "energy" value is 10 times lower than
/sys/class/power_supply/BAT0/energy_now.
The everything else seems ok.
I also confirmed acpi is not reading from /proc/acpi.

I hope this helps.
