parang gusto ko undervolt yung laptop ko ah! 
I adjust the emf per processor state and iba iba ang levels sa mga iba ibang parts nung processor to get the most benefit (depende na sa tweakability nung gamit). Aside from managing individual subsystems within the processor, I also tweak signalling levels and the voltages applied to RAM, the I/O hub, and the GPU. Pero hindi pa ako nagpapatay ng features ng board dahil sayang naman yung features na binayaran (though that can further bring down consumption). Siyempre kailangan din ayusin sa software-side. Ang OS ko is full fat pa din lagi (all features are on), more on power management options ang ginagalaw ko.
I have some undervolted notebooks too, aside from my desktops. Battery run-time improved significantly, and they are whisper-quiet during operation (since the fans can run at very low speeds). Nakita ni Paul yung Llano notebook ko with a 9+ hour run-time with the standard battery (partida, powering a dac pa yun). May Sandy Bridge notebook ako with a 6-7 hour battery run-time on the standard batt (with wifi and bt on).
Generally, mas malakas sa konsumo yung computer (like higher end models or older designs), mas malaki ang benefits sa tweaking na ganito. Pero maski nga sa mga Diamondville at Ontario na sobra tipid na, noticeable pa din.
