Thanks, I followed the guide on my new T440p :D
(guide: http://www.tonymacx86.com/yosemite-...s-rehabman-yosemite-run-perfect-my-t440p.html)
Just some notes.
The DSDT was a little different for me (all the code seemed to be there) so I applied most of the patches there. And use a new version of MaciAsl

I had to modify the patch because was causing errors in compilation, after that, boom Battery Indicator working :D (Battery is showing 00:00 remaining :( and draining kind of fast :'( )

Brightness controls working.

All four USB working.

SD card reader NOT working :(

Touchpad working (but it could use an improvement)
Trackpoint working

Graphics not fully working I see glitches all around.
After following this:[Fix] Intel HD4200/HD4400/HD4600 Mobile on Yosemite
I have graphics fully working.
But I'm getting a kernel panic when connecting an HDMI monitor
HDMI working after deleting AppleHDA kext ( see http://www.tonymacx86.com/yosemite-laptop-support/163847-lenovo-thinkpad-t440p.html#post1043975)
Audio working with VoodooHDA.

Bluetooth card included in intel AC 7260 working if enabled from linux...

Edit1:

Battery DSDT patches are not correct then...

As for draining fast... power management implemented? Is the a discrete graphics device? If so, is it disabled?

Edit3:
KP when connecting a HDMI monitor.
HDMI-audio implemented?

Still getting KP after FakePCIID_Intel_HDMI_Audio.kext.

does it matters if I'm using VoodooHda?

VoodooHDA does not require FakePCIID_Intel_HDMI_Audio.kext. It is only for HDMI-audio with patched AppleHDA with unsupported HDAU id (such as 0x0c0c).

After XX failed attempts of patching AppleHDA, I decided to install VoodooHDA (as it was previously working) and to remove AppleHDA kext.

To my surprise I'm able to connect my HDMI monitor without any config (and without kernel panics :clap:)

The only thing left is Wifi Card, but this is a whitelisted BIOS, any chance of installing a kext for intel cards?

Intel WiFi is not supported.

Compatible chipsets and the procedures for making them work are covered here: http://www.tonymacx86.com/network/104850-guide-airport-pcie-half-mini-v2.html

After one reboot and I'm getting KP when connecting hdmi monitor.

to fix this i deleted FakePCI kexts and patched DSDT with this patch

https://github.com/RehabMan/Laptop-DSDT-Patch/blob/master/graphics/graphics_HD4600_yosemite.txt

and applied this patched kexts
http://forum.osxlatitude.com/index....0-and-1600x900-lcd-mavericksyosemite/?p=49151

Now HDMI works again.

Edit:
I installed AppleHDADisabler kext just in case.
There are patches in my config.plist examples for HDMI reboot issue (the framebuffer patches with "(12)"). You also generally need to implement HDMI-audio.

May not be a concern if you're using VoodooHDA. No idea really, as I've never been able to make VoodooHDA work correctly.

I would avoid installing patched kexts on-disk. Much better to do the patching via KextsToPatch in config.plist.

Thanks RehabMan.

I didn't like the idea of replace Kext either, but for now I'll leave it as it is and wait to brake in the next update then fix it with onfly patch.

VoodooHDA is the only way that I'm able to get audio working. I tried patching AppleHDA multiple times starting from scratch in case i miss something but no luck.

So far VoodooHDA is working fine. I even get the switch to headphones when connecting, haven't tested hdmi audio yet.

Which audio codec do you have?

Note: Luck has nothing to do with it :)
