Re: ACPI strangeness - battery jumping to low capacity and back

[Alexey Starikovskiy <aystarik@gmail.com>]

Hi Christian,

First, it is better if you open a bug in bugzilla.kernel.org against 
ACPI/Battery and attach all your files there, so they will not be lost.
Second, please try latest stable kernel from kernel.org, not Ubuntu one, 
as they seem to be not very careful with ACPI. 

Regards,
Alex.
