Re: Trouble CPU frequency and battery on macbook
Date: Mon Aug 06 2007 - 10:08:03 EDT
Hello everybody,
I got news on this problem, perhaps this will help fixing my problem. I got the speedstep working by adding some lines to the /etc/rc.local script, as described in the debian wiki for the macbook.
But, I still don't have my battery recognized. So I installed an ubuntu
feisty as dual boot on my macbook since the ubuntu documentation says that
the battery of the macbook is recognized without problem and without having
to compile a custom kernel.
But, after installing and updating the ubuntu (I installed from the live CD)
it happens to have the same behavior as on debian --> The battery is not
recognized (gnome applet says no battery is present).
So, I suppose that the kernel parameters are not the cause of this; did I forgot something (a daemon, a program, a module)?
Thanks a lot
Regards,
Alex
