'Underclocking' to stretch battery endurance
Posted: Wed 18 May 2011, 20:48
Today I chanced upon Steve Gibson's very impressive report (related to tablets)
https://www.grc.com/pda/palmpower.htm
Of course some portables will automatically slow down the CPU as battery dwindles but, given Puppy's extraordinary efficiency, and thus performance on 'slow' CPUs (and a handy CPU scaling tool in the Utility menu .. if the available modules work) I wondered if in this respect Puppy's light might be being hidden under the proverbial bushel, and not getting the attention it deserved.
Sniffing through earlier posts on this forum I see that jemimah & co have explored this to some extent a while ago in the Pupeee context, but there does not appear to be much wider interest. Should there be?
One of Puppy's aims has long been the ability to rejuvenate old machines, however declining batteries all too often are the crunch which condemns aged lappies to landfill ... so before I risk trying to reinvent the wheel myself, has anyone else had success using underclocking - via Puppy's CPU scaling tool or otherwise - to keep old portables useful without the painful expense of replacement battery packs?
