There are plenty of sites out there that give advise on this topic, unfortunately most of them are highly ad-infested to the point of being unreadable as well as only containing single bit rather that an overall picture. This is a collection of useful links to source materials as well as steps necessary to install.

Since I have been really happy with the performance and mobility on the Toshiba Ultrabooks (see previous blog entries) I have now chosen to stay with a tried brand and uprgrade to the Z930 i7 model.

Unfortunately this now comes with added hurdles by our good friends at Microsoft in the form of UEFI and the pre-installed disaster that is Windows 8. Instead of totally wiping the system as I did with the Z830 model I decided to install next to Windows 8 as lots of people have reported problems with the UEFI bootloader and the BIOS if you start messing with the pre-installed partitions (specially the EFI partition).

To get an idea on the current power usage and some suggestions on how to improve power-management ‘powertop‘ is a must-have.

sudo apt-get install powertop

For some more detailed suggestions this is a good start:

EDIT: Here are some tweaks if you install 12.04 (Precise Pangolin).

Since I will have to do a fair amount of traveling in the next year I was in need of upgrading my trusted workhorse of Toshiba Qosmio F60 to a more portable option that will be easier on the shoulders during long travels. After doing some research into which of the major manufacturers offer the best support for a Linux based Operating System it came down to a final two: the Intel i7 variants of Samsung Series 9 and the Toshiba Z830.

Since some older hardware (Toshiba Satellite A300 for example) has issues with the current version of Grub as well as the newer Kernel I still need to run 10.04 on some machines.

However since the 10.04 Repository still uses Firefox 3.6 you need to add a PPA repo to upgrade to Firefox 4.

Either go to Ubuntu Software Center > Software Sources and click the ‘Other Software’ tab. Press ‘Add’ and enter ppa:mozillateam/firefox-stable
