This seems to work on the Wind:

Unfortunately you can't access the full load-based-undervolting-underclocking features until you register. I've just bought a key, but it won't let me register it properly, so i'm waiting a reply from support.

Feels promising tho

I've run GeekBench with this active, with no ill effects, and when I unplug it's now estimating my battery life at 2.5 hours! Woohoo!

Sounds good, gonna buy it and use it once I receive my new HDD today and install OSX tonight.

I thought rmclock was a pretty decent utility (also, it's free) used for undervolting laptops.

Doesn't work on OSX tho does it?

Very impressed with CoolBook, fairly cheap too at $10...

Another nice find. I can really see why this OSX sub-forum is heating up with each day :lol:

Hi Guys, just got coolbook but I can't seem to be able add a frequency, I should have a pop up(voltage popup menu) but nothing appear.
I reinstalled couple of time already.

Hi Jerome,

Open a terminal and run "ioreg | grep IOPlat | head -n 1" (without the quotes) that needs to return a model supported by Coolbook (determined by SMBIOS).

Example: (note I am on my real Macbook Pro at the moment, but this is the same sort of output you should see)
Zildgen:~ chris$ ioreg | grep IOPlat | head -n 1
+-o MacBookPro4,1 <class IOPlatformExpertDevice, registered, matched, active$

Hope that helps.

Chris.

Thx Radial & Paulatmodaco, I ran the command and came back as blank, used AppleSMBios 28 and now it works fine.
Really please with that machine, suprise that it works so well.
Can't wait for my dell 1505 pci-e and the extra ram, and off course the 6 cells battery

Thx again guys.

HI Paul, thanks for this.

As you seem to be a few days ahead of me running OS X on the Wind, the best thing for my battery life seemed to be just to follow you, sheep-like, into this Coolbook malarky, so I've just gone ahead and registered the program and upgraded to SMBios 28.

Just wondering if you've got any time-saving tips on setting it up? Are you using the frequency/voltage settings that you've posted in the picture above, or any additional settings? Should I just add these to the 'Battery' section and go for it? Oh, and how do I know that it's working?

Thanks in advance

Carlos

I used all the default settings. I put all the frequencies in the settings for on mains power, and i'm currently playing with the battery settings. I'm toying with the idea of never letting it go above 1GHz on battery to save power, but depends how much difference it will make

Incidentally, when you're running SMBIOS28 you can also use a kernel flag to make your memory appear correctly as 667MHz in 'About this Mac'.
