No sure why you would want to do that, but you can't do it through preference not BIOS. Only way is to physically removing the ribbon that connects to the system board. It right underneath the battery, but you have to be really careful. These things are so fragile, it can easily break and I'm not taking any responsibility for any damage you create.

Not jumpy, but sometimes single click acts as double clicking. There's no further development since Sontrg. The one in my bootpack is the last known working kext. ApplePS2Controller v1.5 is a lot smoother if you want to try it, but it acts as a regular mouse. No scrolling whatsoever. But if you combine it with Smartscroll.app (shareware), you'll get trackstick scrolling with the middle mouse. You could even get touchpad scrolling if you hold down the middle mouse, but no 2 finger scrolling or single finger side scrolling. You could also try Karabiner (freeware), a key remapping app but has the scrolling capability like Smartscroll but without inertia scrolling.

download DPCImanager.app. Get screenshot of status and PCI List. Need to know what hardware you have. Your screen flickering is graphics issue.Might need a dsdt patch. Do you have full QE/CI? What is system info should for Graphics? Also with DPCImanager, click on Extract DSDT, compress the file and upload it.

No need to reinstall. Did the keyboard stop working after you install the kexts, if so, remove the voodoops2controller. No, your wireless adapter will never be supported, no kext ever develop for Intel.

Your wireless card is not supported. Not sure if your BIOS has whitelisting. You could try using an USB wifi or mod the BIOS to remove whitelisting if needed. Start with these kexts first. Place in Kexts/10.10 Kexts.zip

I added the verbose mode just so it's easy to see when error occurs. You could remove it once everything is running. What do you have in /EFI/Clover/Kexts/10.10 or Other? Do you know at least what ethernet card you have?

OpenCL should be supported without the patch mention when using FakePCIID and FakePCIID_HD4600_HD4400

Try this config. That one is way too general. Will need more info regarding your system later on, but let's get it install or at least get to the Installation first Information needed: Max display resolution? ethernet? Intel, Broadcom, other...? wifi? chipset? USB 3.0? SD card reader? etc.. config.plist.zip

DSDT patching for E5520 doesn't seem to work for this model. See here, tried by another member. Just looked through the bootpack again, don't see any issue. All necessary kexts are there. Your Wireless DW1510 should work OOB. Broadcom ethernet should be available too in the bootpack. Try running myHack/myfix again or myHack/Install Extra and point to the /Extra folder.

What fails? No ethernet or wireless not working? I believe for the E5420, ethernet is a Broadcom, look for BCM5722D.kext For Wireless, if you have an Intel, it's not supported. Replace with a supported card like DW1510. Works out of the box.

attach your config.plist.

Only working kext is the one included in my bootpack which you're already using. You could try patching your own, there's a few guides available in the internet.

Yes, the Haswell system is supported which requires a patched Kernel if you're going with Chameleon or use Clover, no manual Kernel patch is required. You could start with here to create an USB Installer with Clover UEFI

Install this. After wake, speaker will work, but not headphone To get headphone to work, plug in the jack, place system to sleep and then wake it up. No other known fix at this time for this particular ALC292.

I've made a little progress. Updated DSDT patches Now works: USB 3.0 works with native AppleUSBXHCI Webcam works SD Carder works DVD Player works Touchpad scrolling with 2 fingers (ApplePS2Controller v1.5) Trackstick scrolling with Smartscroll.app Battery status with ACPIBatteryManager v1.55 Speaker/Headphone (autoswitch) - VoodooHDA 2.8.4 (control by keyboard keys F1, F2, F3) Sleep works selecting from Apple menu (Not with LID close nor wake with LID open) Fixed with new DSDT Sleep with LID close, but won't wake with LID Open. Just tab the power button (Thanks to Bronxteck to point out that I'm missing the PNLF patch) To control brightness, ScrollLock to decrease and Pause to increase. Unfortunately this new keyboard removed the Pause key...so warning, unable to increase without some keyboard key remapping. Are you able to scroll with touchpad and trackstick with voodoops2controller v1.8.9? I believe the latest version is 1.8.14. Rehabman's brand is mainly for Synaptics, with minimum support for Alps. E7x50.zip DSDT.aml.zip

Use Chameleon Wizard v 4.4.1 and you'll see it under org.chameleon.boot.plist tab.

As I said, with the Nvidia card you don't have sleep. Once the screen goes blank it initiates sleep, only way to recover is to reboot. Go to preference to have display off to never and HDD sleep to never or use Caffeine.app to set system to not allow sleep.

upload your config.plist

Means your graphics is not loading. How did you get to steps 14 and 15 if you haven't even install to the HDD yet? Please follow guide carefully.

Use my updated DSDT and skip the kexts from 14 & 15, but make sure to install this as well.

MyHack won't work with Yosemite. Try my guide. Bootpack on post #3 of the guide.

Sorry, I just noticed that you have 10.10.1 from your first post. Undo the fixes and redo them after you upgrade to 10.10.3. This is a good reason to have you system specs on your signature. Easier to see than having to read through the whole thread.

E7240 has HD4400, not HD4000. See bootpack here. E7x40...

See Herve's guide here. Confirmed to work!

Did you add the code to the proper location? If not, it could corrupt your config file, which no longer loads, which could stop your system from booting correctly.
