Hithere,

i've got a new Schenker S403 (Clevo W740SU) with Debian jessie running on it.
Battery information and things like that on Windows works fine.

If i try to read the battery status per "acpi -bi" i get a "Battery 0:
Discharging, 35%, rate information unavailable" back.

A cat on current_now gives me a wired error message:
root@nb:~# cat /sys/class/power_supply/BAT0/current_now 
cat: /sys/class/power_supply/BAT0/current_now: No such device

I think its a Kernel Bug, since the battery current reading works just fine
under Windows.

When i plug the notebook on the AC Adaptor, the file reads just fine.

I've attached an acpidump.

Thanks!

Greetings
