maliknet95 Posted October 19, 2014 Share Posted October 19, 2014 Hi Guys, I have installed OS X Mavericks on my Latitude E6320, Everything is okay but one function is not work. It is woke up from sleep, always black screen. I already try to set system password on my BIOS to force screen to display input password firstly but didn't work. Please advice me and give me a solution. Best Regards.... Link to comment Share on other sites More sharing options...
adriandb Posted October 20, 2014 Share Posted October 20, 2014 Everything is okay but one function is not work. It is woke up from sleep, always black screen. I only ever saw this issue when I loaded the VoodooSDHC.kext. If you have that in your extras try removing and then running myFix again and rebooting. You'll lose the SD card reader, but you'll have the ability to sleep the system. Link to comment Share on other sites More sharing options...

Because Woke up and Card Reader is very important features to me. Whether any patch for VoodooSDHC.kext to fix it?? Link to comment Share on other sites More sharing options...
dfiore Posted October 20, 2014 Share Posted October 20, 2014 you can actually load the kext for SD card on an as needed basis to keep sleep working. Put the VoodooSDHC.kext in another folder like /Extra/TempExtensions/ and run this command replacing the proper path as needed "sudo kextload /Exta/TempExtensions/VoodooSDHC.kext" once you done using the sd card you will need to unload the kext "sudo kextunload /Exta/TempExtenstions/VoodooSDHC.kext" Note, this will not persist after a reboot, but will cause the blank screen if you sleep the PC while the kext is in loaded.

dfiore Posted October 20, 2014 Share Posted October 20, 2014 Sidenote, anyone taken the plunge on Yosemite yet? I grabbed the BROADCOM BCM94352HMB in prep for Yosemite and have it working in Mavericks now, albeit without the ability to pair any bluetooth devices. Ive held off from mucking about with the Bluetooth until I can get to a clean Clover based Yosemite install. Link to comment Share on other sites More sharing options...

Dave Hi Dave, I already remove VoodooSDHC.kext and run MyFix with MyHack then i reboot my OS X. After reboot i test the sdcard slot and not run so VoodooSDHC.kext totally removed but if i sleep my OS X and i woke up is still black screen. Any idea?

dfiore Posted October 24, 2014 Share Posted October 24, 2014 Malik, As noted, you cannot have the VoodooSDHC.kext driver loaded with the system and retain sleep. If you want to use the SD card, you will have to load the driver manually when you intend to use it. Please read the instructions above and attempt to load the driver, if you come across any errors, ill be glad to review and help you get it going. Thanks, Dave Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 24, 2014 Moderators Share Posted October 24, 2014 Folks, to get SD Card reader working without killing sleep, try this Credit goes to joe82. The VEN/DEV will not be the same. For my E6420/E6430/6430U, it's pci1217,8221 You could skip the DSDT edits, it'll work fine without it. Enjoy! 1 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 24, 2014 Administrators Share Posted October 24, 2014 I confirm it works (verified on E6440 with O2 Micro SD controller pci1217,8520), so should also be Ok on E6320. Link to comment Share on other sites More sharing options...
