Hello, I use this guide to install Snow Leopard on my system.  I used the 10.6 disc, then installed all the kexts that the guide links to on this post.  It worked properly, and I used OSx86Tools to clean shop and fix permissions and what not to get the system up to speed.  I then used the same OSx86Tools to install TeaTeam's 10.6.4 kernel so that I could upgrade to 10.6.4.  I then used OSx86Tools to re-install the kexts and fix permissions and the system runs like a dream now, with ONE EXCEPTION.  While using the AC adapter, the CPU scales fine as observed using CPU-I.  But on battery, it's stuck at 800MHz.  I don't know what kext controls this scheme, but I'd like for it to scale all the way to 1.6GHz on battery as the system is really slow @ 800MHz...  Can anybody tell me what's going on?  I've searched and searched and searched but can't come up with anything...  I'm completely new to OS X and Linux, so I feel I've come along fairly well so far...  Thank you for your help!

It sounds like Voodoo Power Mini isn't loading.In the folder you download,where CPU-I is, there should be anonther app called Kext Utility,run that and restart

voodoo power management kext is properly loaded for me and still no dice from extra or s/l/e cpu downclocks

What does s/l/e cpu downclocks mean?  My cpu, while on a/c power, clocks down to 800mhz when i'm not doing anything and then scales back up to 1.6ghz under load...  It's just while on battery it's stuck at 800mhz....  I'm going to search for a newer voodoo mini kext and d/l that, do i have to remove the old one?  and if so, how?  I know how to add kexts just fine but not sure on removing them.....

s/l/e means system library extensions folder...cpu downclocks was just a fragment should've put a comma there or something...but still looking for a fix here

This is a Intel SpeedStep thing. SpeedStep basically scales back your processor to save energy while unplugged. While plugged in, the CPU should scale to about 600Mhz (although I don't know what processor yours is) but when an application loads should run at 1.6Ghz. On mine, when on battery it is sorted of restricted at between 600-800 to preserve battery life.

Mine isn't too bad at 600Mhz (mine is on battery right now and it's easily usable) but the fact the battery is total {censored} is more of a problem, because I barely get an hour and half out of this thing and for what it's worth it may as well run at full power. Not sure how it can be fixed.

Could anyone find a solution for this by any chance? I have found a funny workaround and I explained here how: http://www.insanelym...p...95180&st=60
