Moderators Jake Lo Posted December 27, 2013 Moderators Share Posted December 27, 2013 Does anyone have problems running with multicore on? When I have more than one core enabled, it'll boot the log on screen but shortly after, the screen goes black and everything shuts off with the power light still on. Do you have the nvidia optimus enabled or you only have HD3000? Running with muticore works fine for me. Is the light blinking or just solid light?

LittleDragon Posted December 27, 2013 Share Posted December 27, 2013 Do you have the nvidia optimus enabled or you only have HD3000? Running with muticore works fine for me. Is the light blinking or just solid light? I have Optimus disabled. I think I have it sorted out. Turns out, it wasn't really shutting down but trying to go into sleep/hibernate all the time. I turned Speedstep back on and that seems to resolve that. Everything is now turned on... all cores, hyperthread, turbo, speedstep... I now have run into a second issue. I can't seem to get two external displays going with my E-Port dock. I can have one external and the built in display going but as soon as I plug in a second external, it all goes blank until I unplug one. Kind of a bummer, took me forever to get both displays working with ML10.8 Link to comment Share on other sites More sharing options...

sandflee Posted January 27, 2014 Author Share Posted January 27, 2014 Ramon, Enable Optimus from the BIOS screen. That will disable NVS 4200M and use the HD3000 graphics. With the revised dsdt, it will enable sleep to work. Link to comment Share on other sites More sharing options...
ramon Posted January 27, 2014 Share Posted January 27, 2014 How can I enable Optimus? Sorry but I've never seen Optimus in bios Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 27, 2014 Moderators Share Posted January 27, 2014 How can I enable Optimus? Sorry but I've never seen Optimus in bios Go to the BIOS, under Video. If you don't see Optimus, means you only have the integrated Intel HD 3000 graphics. Link to comment Share on other sites More sharing options...
ramon Posted January 27, 2014 Share Posted January 27, 2014 I can't enable Optimus because the pc is locked from my factory. Do you know how to unlock bios settings? Link to comment Share on other sites More sharing options...

If you owned the system, you could contact Dell to unlock it. Otherwise you could follow my other guide with Optimus disabled here. Link to comment Share on other sites More sharing options...
zodiacg Posted January 28, 2014 Share Posted January 28, 2014 my USB installer stuck at: P-State Stepper Error 18 at step 35 in context 2 on CPU 0 and will go into a kernel panic after a long-time waiting. sometimes go straight into kernel panic also, what do i need to modify if i want to disable optimus? i don't mind whether sleeping works. but i have a linux installation and using bumblebee to support optimus is really a mess. ===== Updated: I generated a ssdt.aml using ssdtPRGen.sh and replace the one in the Extra folder. now i can see the language choosing screen. but another problem pops up i can move my cursor but i can't make clicks. while booting it says VoodooPS2Controller.kext loading failed. do i need to do some editing to make it work on my own laptop? ===== Updated: I deleted AppleACPIPS2Nub.kext, and now i can use the mouse normally. but the installation failed at about 18 min remaining, with no myhack window popping up. and my usb stick is broken now... it became read-only and there is no such switch on it. i guess i have to wait until i buy a new one Link to comment Share on other sites More sharing options...
