On this gentoo howto they not only recommend using ATI's powerplay but actually give some output that allegedly comes from running it:
http://www.gentoo-wiki.com/HARDWARE_Apple_MacBook#Underclock_ATI_graphic_card I presume this is a reference to the MBP since the MB does not have an ATI card. When I run 'aticonfig --lsp' on my MBP C2D however I get: Error: POWERplay is not supported on your hardware. I'm doing everything at 32 bits - my system and the ati driver. Has anyone managed to get powerplay to work? This might go a long way towards saving battery life. Also, my fan seems to constantly whir in the background (like now ;->). I have applesmc installed but have left the fan's on automatic so far. I haven't figured out what units the temperatures temperature_0-6 are in so I don't know if the fan's should be coming on but it seems to me that they come on too quickly in Linux. In OS X the processor temperature can get very high before the fan's are raised over 2000 rpms. Does anyone have a way to get more reasonable fan speeds - particularly for a C2D machine that heats up less? thanks, Sheer ------------------------------------------------------------------------- Take Surveys.
