Did you ever fix this? I have exactly the same problem with similar specs.

Hi, thanks for the tip, I actually had tried that, with no luck. However, I actually managed to fix the problem! I installed the NVidia Web Driver (http://www.nvidia.com/download/driverResults.aspx/78853/en-us), and then in my org.chameleon.boot.plist, added the string nvda_drv=1, and then in...

Hello, I updated my build (i3-3245, GA-B75M-D3H, GT640) to Yosemite, and have recently been having issues that didn't occur in Mavericks. When I try to boot, it takes multiple tries to actually get into the system for some reason. I either get no signal to the monitor after the boot screen (i.e...

THANK YOU! I forgot about that! Now I am getting way more P-states. System is running nicely now. Thanks so much! I also thought that -xcpm was only for haswell?

Hi, I did that, there was no kernel panic, but I still only have one P-State. To patch the kernel, I went to the folder described in the thread, and then ran these commands: was that correct? Thanks perl -pi -e 's|\xe2\x00\x00\x00\x02\x00\x00\x00|\x00\x00\x00\x00\x02\x00\x00\x00|g' kernel perl...

Sorry, I am using Chimera 4.0 which came with Multibeast. Thanks

I tried it and the system booted without panic, but I only get PState 8. If it means anything, i also get Warning: 'cpu-type' may be set improperly (0x0603 instead of 0x0703) in terminal but it is detecting the cpu correctly (i5-3317u). Also in DPCIManager, the output says "P States: I/o...

Hi Rehabman: I have attached a picture, as well as my ssdt.dsl output. I tried both workaround 1 and 3. ssdt.dsl output: /* * Intel ACPI Component Architecture * AML Disassembler version 20140210-00 [Feb 10 2014] * Copyright (c) 2000 - 2014 Intel Corporation * * Original Table Header: *...

Sorry about the confusion, I updated my profile, I apologize for it being not up to date. My laptop is an IdeaPad U410 with the Core i5 3317U processor. I think the smbios of MacbookAir5,2 would work for that? I am using DropSSDT=yes, and the AICPUPM kext is installed, and was patched using...

Hello, I tried using both ivy workarounds (1 and 3). However, I received a kernel panic related to the CPUPowermanagement both times. I did patch the AICUPM in multibeast initially, using the Multibeast for Yosemite. Is that correct? Is there a reason why I would be getting KPs for the...

Hi RehabMan, I have attached the files you asked for. Thanks!

@jdubb: Thanks! I think that actually might have been what was causing it. @Rehabman: I actually think power management is not working properly on my system. In the IOReg, it shows that the right files are loaded, right? I have an ssdt and smbios for Macbookair 5,2 as per the thread you linked...

Hi Rehabman, Yes, I did forget to apply that patch; it was giving an error, but now it worked in the dsdt, and it is working. Thanks a lot for your help, now everything seems to work properly (fingers crossed). :D

Hi RehabMan, I think I've fixed the power management, here is my update IOReg, I changed the SMBIOS and made a new SSDT. Now everything from my initial post is working, except the lid sleep. I ran the command you told me to use earlier, and everything came out with a 0. Is there something I am...

Okay, thank you. It seems to be working fine right now, if it stops, I'll check the log. How would I get the power management working? I did make an SSDT using PikeRAlpha's script; I'm not sure what else I should do regarding power management, I always have issues with trying to set it up:P...

Hi Rehabman, I have attached my IOReg. Thank you!

Hi RehabMan, Thanks for your reply. I installed the kext as you said (ToledaARPT), and now I have WiFi working, so thanks for that. I am working on the audio issue as well as the sleep issue, but I have another problem. The trackpad is not working anymore, and I'm not sure why, it seems like...

Hello all, I have installed OSX Yosemite on my IdeaPad U410, and most of it works fine. There are some issues that I am having and wondering if anyone knows how to fix them. I have looked through the combined thread for mavericks, but am having trouble finding solutions. Problem 1: Wifi: I have...

Hello, I have an Ideapad U410 with the 1TB HDD and 32GB mSATA SSD cache option, and am interested in running OSX on it in a dual boot configuration. However, if possible, I want to avoid having to wipe out my Windows 7 install that's on the HDD. Is it possible to put in a bigger msata SSD and...

Hello, I actually managed to find out what I was doing wrong. The sound in system preferences was set to the wrong output :P, now everything works when I changed it from digital out. I recommend that others with this problem check this first, because the system did not automatically switch to...
