Hey guys, could anyone here help me out?
I went through the 10.5.6 installation guide and got stuck right here on the Battery stuff. Since the installation i haven’t seen any battery options for my dell, i tried removing both IntelEnhancedSpeedStep and AppleIntelCPUPowerManagement, then installing the voodoopower.kext again and still my battery meter does not appear, anywhere, no options for ac power/battery and on the Power Management Control application it says “Kernel Extention: Offline”

10.5.6
2.00 core2duo,
4GB 667
batt – 6cells

any help would be most welcome!!! thanx in advanced

I am getting 4hrs and 20 min in windows7 with a 6 cell battery. Should I be able to expect the same performance after using the ktext. I go to school and battery life is very important to me. If I can get at least 3 hours out of the battery I should be good. is this possible?

Got a solid 2 hours 10 min with the standard battery. What I had going on (real heavy wifi n’ disk usage):
Music/itunes 9 through homeshare with headphones-about an hour
RDC to control a windows 7 pc-on almost the whole test
Web Browsing
Low screen brightness
Stream hypem music through headphones-15 min
Stream hypem through speakers-15 min
Streamed video from pc-15 min
Ran xslimmer 3gb of 10 freed
Ran monolingual, 609mb freed

I’m going to test a lower voltage. I read someone with the same proc in an Acer laptop successfully had 950mv setting for all steppings.

By: Steven

Steven — Tue, 15 Sep 2009 08:03:25 +0000

Finally tried modifying the kext. I use rmclock in windows and I know it’s safe to have a max voltage of 1.015V (1015mv) so I entered in the kext, set voltageoverride to true and set min voltage to 850. The processor is locked to a min 950 though, I just wanted to give it a try. My max temp is hovering around 58. Idle temp is 46. I’ll have a battery test tomorrow. I may try changing the other setting to throttle up slower and throttle down quicker. copy and paste this over the original section in the kext if you want to use, the kexthelp it and repair disk permissions.

Brightness on battery power is the minimum.

I didn’t edit my voodoopower.kext, What sort of processor do you have and what brightness are you using your laptop on?

By: Tom

Tom — Fri, 28 Aug 2009 02:17:03 +0000

Hi Genaro, what about sharing your settings? (I mean, the step 6)
Because as it is, I’m not getting 2hrs and 30 min, just 50min or 1hr… :S something must be wrong (I didn’t modify any file)

Thanks in advance.

Yes it does and lucky you if you have a 9 cell battery, I’m envious.

Does it work well with the 9 cells battery too?

my battery meter does not appear, in the the system preferences (energy saver) shows like my inspiron is a desktop computer, no option about ac power/battery.
How can I fix it? (sorry about my english)

Could you, Genaro, tell us about if you modified your Info.plist ?
I am getting about an hour on battery (and I think 6 cells is the lower battery, the one I have), and the app show that it is working a VoodooBattery 1.2.3.
I followed your guides from iPC 10.5.6 hackintosh and upgrading to 10.5.7
Everything works properly, but I wanna know about this issue with battery.
Also, I can tell you that in my Settings – Energy Saver there isnt any of “power saver” “balance” or that kind of things that should be there.

Ryan: ning this warm. I don’t

The only ting worked for me with over heating to turn off the AutoThrottle feature of the GenericCPUPMControl at the startup it keeps the temperature to 70c average at normal use.

ryan: nd 65C it drops back down.) Now while t

I have the same problem, with the same processor, but in my case it gets up to 68c without a task and till 98c on vmware.

Rich: You need to use either IntelEnhancedSpeedStep OR VoodoPower not both. The current recommendation is VoodooPower. So get rid of IntelEnhancedSpeedStep and remove the AppleIntelCPUPowerManagement kext as well.

See the latest posts for instructions on how to do these things without making a mess of things.

The temps reported by GenericCPUPMControl are not always accurate. Do you fans run a lot? Do they ‘roar’ even when your doing nothing? Does your Laptop feel hot? If you are truly running hot you’ll feel it over the area around the t, y, g, h keys (right over the cpu) and over the radiator in the upper felt corner… Let us know how you make out.

Hi
i have followed the guide above and looked all over the site but i cant seem to find anything to help. i believe the laptop is overheating and this is causing it to lock up. i am running 10.5.7 and both GenericCPUPowerManagement.kext and IntelEnhancedSpeedstep.kext in my extensions folder. using GenericCPUPMControl typing this cpu is at 70C the load is changing but the frequency constant in the middle under load installing office the cpu is at 100C and the bottom of the laptop is hotter than the sun. It also shows voodopower.kext kernel extension online and auto throttling is indented.
Thanks Rich

I did everything and everything fine: 47C or 51C at most.

Only one problem: I think I got confused with the VoodooBattery.kext and installed twice (and then I installed the VoodooPower.kext completely ok) but now I have TWO batteries indicators (and one battery percentage) at the top of my screen.

Do you know how can I get rid of the second one ??? Thanks in advance.

Something interesting: With iDeneb, Temperature Monitor reads 44C idle, With iPC I was using GenericCPUPMControl showing an idle of 60C+. When I used GenericCPUPMControl on iDeneb it showed a similar idle. Now when I altered GenericCPUPMControl’s TJMAX setting to 85C it showed the same temp or very close with Temperature Monitor. (44C idle)

Temperature monitor seems much more accurate (Hopefully) Maybe I just didn’t have the right TJMAX setting in iPC when viewing the temps? Thus it showing the incorrect temp. and I never tried Temperature Monitor on iPC to show a differen’t temp.

OR maybe I really still don’t know and my laptop is overheating

Ryan — Sun, 07 Jun 2009 04:12:05 +0000

Neither system had a issue with CPU peaking out. The load average stayed consistent with the task performed. The difference was just in the temp. I now have a idle temp of 41C on 10.5.7 iDeneb vs the higher 65C+ idle on iPC

I’ve actually hit 78C during the CS4 Collection install while watching a movie but it quickly decreases on iDeneb. All the temp. seem to fluctuate greatly is this how processors normally tend? I’ve never really watched this closely to CPU temps haha

Oh yeah and latest bios just updated the other day, and never been dropped.

BUT! I’m happy to report that I have 10.5.7 running smoothly with iDeneb and the 2 driver packs used with this iPC install and the ACPI Kext used to fix the trackpad and keyboard after 10.5.7 update.

@Ryan I don’t see a MAX of 65C as cause for great concern. The processor is rated to 100C before it slows down and then halts. However, cooler is always better. There are so many variables that could account for the heating problems you have had running iPC vs iDeneb, I wouldn’t know were to start. I do however suspect that it was mdworker and/or mds, which are involved with keeping spotlights index up-to-date.

A couple of questions; did you notice the process activity levels (load average or % processor utilization) before and again now? does the fan run more often and faster (louder) now than with iPC? What is you bios version? Has you machine ever taken a fall or been knocked around more than normal? I ask because the way these things are designed, the heatsink/thermal pipe/radiator assembly is made to be cheap not effective. The thermal paste is applied as a “tape” which makes it easy to get a bubble or a bare spot. Banging it around can flex the heatsink assembly also creating a bubble.

Nothing I tried with iPC worked, still resulted in the 60C+ idle temp with it reaching up to 80C

So I gave iDeneb v1.4 a try, Without removal of any kext or Voodoo power installed it runs at around 51C idle with proper removal of kext and Voodoo Power kext package installed it sits around 45C and gets up to around 65C at time of use. Atleast I can see a good temp. drop now. (Usually when it gets around 65C it drops back down.) Now while this feels like a more normal idle temp the fact that it gets up to 65C still worries me. What do you think about this temp range? (it got up to 68C during the 10.5.7 update)

All in all I’m unsure as to why iPC stays so hot. I know its a kext or combination thats off but I haven’t found anything to drop the temp.

Btw, I have the Intel T5750

Dell 1525 (122B model)

I’ll keep updated on any fixes that help me incase anyone in my situation needs the same help

I wonder how many people actually have an issue with the processor overheating and just don’t know about it.

Anyways so I got my system to work without the ACPI fix, but this overheating issue is still a problem. Same as before.

By: ryan

ryan — Sat, 06 Jun 2009 14:35:12 +0000

The Voodoo kext make no difference in temperature. Neither does removing AppleIntelCPUPowerManagement.kext, Also tried removing AppleCPUthermo.kext and extensions.mkext which seemed to have helped some and this made no affect at all. I’ve tried all combinations of these with no avail. All followed up with ‘Clear Extensions Cache’. The temperature changes rapidly even at idle (61c-75c) but usually stays around 62c

The only thing I could think of is that before I tried that ACPI fix was that I’m fairly sure it wasn’t running this warm. I don’t think that fix has any affect from what I know but I’m going to give it a try. Figure i’ll recieve the same temperatures.

Genaro Bonilla — Sat, 06 Jun 2009 08:22:31 +0000

That’s really strange that the temp is that high, after removing the AppleIntelCPUPowerManagement.kext did you “Clear Kext Cache” try that and restart and see what you idle at.
