doresreturns Posted February 6, 2015 Share Posted February 6, 2015 Ok, I did it. Took me some time stalking RehabMan's posts I realized that it's only done by just adding _OFF() and editing stuffs. And now my brightness slider is working! (It didn't work until now ) The thing left is my P-states and temp (if it's related)... I only get 4 P-states on battery (see the pic) And 7-8 P-states on AC (with I/O error, throttling down to xxHz) So, I'm going to remove the original ssdt.. But I wonder if there is any side effect or not? I hope it will help with the heat and give me better battery life.. I'm so happy. Thanks! Link to comment Share on other sites More sharing options...
vusun123 Posted February 7, 2015 Share Posted February 7, 2015 Just load DSDT and graphics SSDTs, that's all. Also you need to disable in _REG and _WAK for permanent dGPU disable Link to comment Share on other sites More sharing options...

johnrey Posted March 21, 2015 Share Posted March 21, 2015 Hey there, I have a Sony VAIO SVS 13p and everything was working perfectly, even power management in Yosemite and Wake/Sleep.. until a few days ago. I just don't know what happened or when it happened but from one day to another my sleep/wake broke.. Not only that, since then I get weird problems. For example when I shut down my laptop, it restarts automatically. And my CPU is 100% most of the time, always 2,90GHz (on battery) and 3,40Gz on ac cord. I noticed that when I booted without caches or (disable hibernation mode) the CPU went back to 1,20GHz.. Because I couldn't figure out the problem I did a fresh installation and patched the DSDT again and generated the SSDT file. Now I'm always at 2,9/3,4GHz.. What's the problem? Everything was working before.. why not now? Not even in Mavericks anymore.. Link to comment Share on other sites More sharing options...

If you have i7, just use KernelPM and -xcpm, and do not generate SSDT (didnt work for me at all) you will get 4 normal P-stats and all the turbo mode states. And I still have sleep and wake, I donno what have you done Link to comment Share on other sites More sharing options...
johnrey Posted March 21, 2015 Share Posted March 21, 2015 What's funny, is that I had generated SSDT before Clover (UEFI) in my Chameleon (Legacy) installation and kept it after switching to Clover and had working Power Management with more P-States (without -xpcm/no SSDT). Only thing I can think of that changed since then is that I replaced my optical drive with a HDD caddy to have 2 hard disks. EDIT: I removed that SSDT file and tried with -xpcm and Kernel PM.. My CPU still uses 100%. 2,9/3,4GHz all the time. Maybe it's something else. EDIT 2: I tried with different SSDTs generated by different tools. The one generated by ssdtPRGen 15.6 (and MaciASL I think) got me stuck at 0,8GHz but my older SSDTs and the new generated by Vietnam Tool give me 2,9/3,4GHz.. 1 Link to comment Share on other sites More sharing options...
midi-sama Posted March 22, 2015 Author Share Posted March 22, 2015 heh, same as me but for me, I have 1.2 1.9 2.4 and 2.9 GHz on battery, on AC I have more (rarely up to 3.6 since Sony throttled the CPU, even on windows it can't get to the max freq!)

johnrey Posted March 22, 2015 Share Posted March 22, 2015 heh, same as me but for me, I have 1.2 1.9 2.4 and 2.9 GHz on battery, on AC I have more (rarely up to 3.6 since Sony throttled the CPU, even on windows it can't get to the max freq!) 3,6GHz is max for single core, 3,4GHz ist max for dual, as far as I know. But that's not the problem. My problem is, that can't get lower than the max frequency. I constantly get 2,9GHz on battery and 3,4GHz on ac cord and over 60°C without doing anything. Just booted into the system. I can see kernel_task using a lot of the CPU. When I let it sleep and wake, it dropped to 1,2GHz and 40-45°C. Really weird behaviour. Something is wrong here.

midi-sama Posted March 22, 2015 Author Share Posted March 22, 2015 Omg! I though it was only me! I have the same problem, but not as sever as yours!! Link to comment Share on other sites More sharing options...
johnrey Posted March 22, 2015 Share Posted March 22, 2015 I will put in the optical drive and try again and see if something changed.. the max. 3,4GHz is normal for dual-core. only on single you will get 3,6GHz. But with working power management there are more P-States. Link to comment Share on other sites More sharing options...

johnrey Posted March 22, 2015 Share Posted March 22, 2015 Well that's the only thing I did since working PM. I've read that the 100% CPU on kernel_task issue could be due to things like SMC, ECC, etc. and I just don't what else to do... Link to comment Share on other sites More sharing options...
johnrey Posted March 30, 2015 Share Posted March 30, 2015 Hey midi ッ, what P-States do you get with/without SSDT? Link to comment Share on other sites More sharing options...
midi-sama Posted March 30, 2015 Author Share Posted March 30, 2015 I get 12 20 24 29, and all the turboboost stats. Link to comment Share on other sites More sharing options...
johnrey Posted April 2, 2015 Share Posted April 2, 2015 I let it run several times for a while and got these stats 12, 17, 20, 22, 27, 28, 29, 30, 31, 32 33, 34. Some of those number appear most of the time, some are rare. Link to comment Share on other sites More sharing options...

lnguy193 Posted April 11, 2015 Share Posted April 11, 2015 Hi Midi, I am trying to instal Yosemite into my Vaio SVS1512DCXB, I completed all the steps to prepare the USB but I could not boot into USB eventhough I selected boot from USB drive. The computer just flashed the vaio logo for 3 or 4 times and then got stuck at Vaio logo. I have win 8.1 on it also UEFI boot. Thanks for help.
