Hi all!
After some promising reports here I installed Ubuntu beta 2 on my Vaio 
Z13 (in the meantime with  sudo update performed several times). While 
most things work fine, power consumption is a big issue. Even with 
wireless turned off, power consumtion is always about 25W, typically 
27W. The nvidia card is always running but I doubt that this alone 
explains this much. I also ran the powertop utility and switched all 
suggestions to "good" with the exception of killing the external mouse.

In the reports of power consumption of about 10W there have been notes 
on a hacked bios. Is this neccesary? I use my machine (up to now mostly 
under Win 7) for serious work and can't afford a risky operation. I case 
one can do it a modest risk, where can I find a description?

Any suggestions?
