Haha, sounds super boring compared to 2004 when I bought Fujitsu Siemen's cheapest Pentium M laptop and had to build some kernel modules, build custom rules for power saving scenes (as there weren't that much of ready rules) and find the most optimal parameters for every module and CPUFreq configs etc.
Also, figuring out the sequence of disabling modules etc for suspend to disk and suspend to ram sleep modes with more custom scripts was super fun. Managed to squeeze whole 8 hours from a battery that was supposed to work 4-6 hours in Windows XP. Fun times.
