Do they make some difference? I read in Ubuntu wiki that actually it has good power configuration management out of box.

No. pm-powersave now takes care of that functionality. The relevant files are:

/usr/lib/pm-utils/power.d/laptop-mode
/usr/lib/pm-utils/power.d/95hdparm-apm

http://manpages.ubuntu.com/manpages/raring/man8/pm-powersave.8.html

Also, see the comprehensive answer here: Is "laptop-mode-tools" still relevant for 12.04 and the 3.x kernels?

If you want further improvement to power consumption install TLP via its PPA from www.linrunner.de/tlp its far more effective and implements true power saving profile to your laptop.

Be careful with TLP, in my case it did something funky with the system and made it very slow. Also, I have not seen any objective tests showing that TLP is any better or worse then the default on Ubuntu 13.04. –  asp Jul 18 '13 at 16:14

I have it in different laptops from AMD to latest Haswell CPU and AMD netbooks and never faced an issue. Also tests have been done by quite a few sites that have testified to TLP's effectiveness regarding power savings.
