Hello! I thought about the power consumption. Maybe we can track the problem down some other way...
1. Is the output of '/proc/acpi/battery/BAT0/state' reliable? If it is,
we can use it for testing, otherwise we have to test how long the battery
really lasts.
2. As far as I remember, the MacBook is very similar to the MacBook Pro in
the hardware it's using. The main difference is the GPU.
How long does the battery of the MacBook under Linux last in comparison to
MacOS X?
If it's a small difference, so our problem is the power consumption of
the ATI GPU (assuming the Intel-GPU draws as less power under Linux as it
does under MacOSX). On the MacBook we have the advantage, that it's an
open-source driver.
If the power drain is as bad as on the MacBook Pro (and we checked the
Intel-GPU driver, that is's using all power-saving states available),
the problem lies somewhere else...
To check these, we need some output of the MacBook's /proc/acpi values or
somebody who helps us to prove these theory...
Any comments to these thoughts? Any errors in it?
Best regards
Sven
