Technically the power savings stuff would be better off via event.d... but that can be a task for another day. :) With display brightness set to the third from bottom, the battery applet is telling me I have 7 hours of battery life. https://gist.github.com/2382839 Here is a /etc/rc.d/rc.local (make sure its executable) that takes care of setting up the machine for power savings along with changing the schedular for the SSD.

Thank you for the review. I bought a samsung ultrabook, but it's the series 5 instead of the series 9. So, probably my question does not apply to your case. But even so, I'll write it. I noticed that, using Windows with no applications opened, the fan never turns off completely, unless I use the Fn key for the silent mode. Otherwise, the fan keeps working, even if it's not very loud. Should this be normal? Or it may have a problem with my unit? Using Linux also with no applications opened, the fan never turns off as well. And, in fact, it even seems to be louder. I read that before kernel 3.2, the fan was continuously spinning. But I'm using kernel 3.3 and I seem to have the same problem. In your case, did you notice any difference between using windows and linux, regarding this issue? Thank you for your help! Hi!

I wasn't sure about the recovery partition so I just kept it to be safe in case I needed to return the laptop to its original state with the Windows 7 install. Given Samsung supply a recovery CD it shouldn't matter as long as you have a USB CD drive to boot from. In Linux (using gparted) the recovery partition is reported as being 20GB used. I'll check later to see what Windows says. Hi Michael,

Did you know that Samsung are running a promotion that allows you to claim the VAT back when you buy a new series 9? The details are here http://www.samsung.com/uk/vatback/. What I wanted to ask about was the partitioning in preparation for installing Linux. You deleted the hibernation partition gaining about 5GB but what about the recovery partition which is about 22GB. Did you foresee a problem with deleting this or did you think that the Samsung recovery system was actually useful. Bizarrely, Windows disk management reports this partition as 100% free so I assume that the 'initial backup' that is supposed to happen when you first start the machine did not, in fact, happen in my case for some reason. This only serves to further reduce its apparent value in my eyes and I am tempted to use the 22GB for something more useful. Hi John,
