Re: Power usage of 12.04 on vaio Z13

 

Thanks for all the answers. I'll work a bit on this in the weekend.
In principle I feel that it would be so much easier if Sony had someone
to collect such information. As my Z13 has a Display fault I'll go
either for a new Z or a Macbook which is Unix-ish enough for me.  
Thanks
Reinhard
