 ====== Power Management ======
 A while ago I had a Lenovo X121e as a lightweight "surf anywhere" system. Because I also create content and I like my freedom, a tablet is not really an option for me. Because of (amongst other things) its advertised battery of up to 10 hours life I chose the X121e.
-Of course the pre-delivered OS got replaced by Debian immediately. But what a shock, the battery only lasted about 3 hours! I was really disappointed, but then came across [[http://linrunner.de/en/tlp/docs/tlp-linux-advanced-power-management.html|TLP]], an advanced Power Management tool for Linux. Using TLP the battery lifetime more than doubled on the X121e. Still no 10 hours, but I can live with that. The amount of extra battery life is still dependent on your system, I think twice as much battery life is really not what TLP can do on every system ;-)
