I am having a strange issue with the keyboard on the T420.

Sometimes when it boots it acts as though a key is stuck, usually repeating the number 7, or another character like @@@@. Occaisionally the keyboard does not work and I have to reboot once to fix it.

Has anyone else seen this. I am using the ThinkpadUltraNav, ApplePS2Controller, and AppleACPIPS2Nub kexts that came from tluck's ML-Extra+Kexts.

If anyone has seen something similar or has a suggested fix let me know. Thanks again to everyone for their contributions to the thread, particularly Manwel50, never would have been able to get my T420 up and running without it.

I had the same problem. Put the extensions in /Extra/Extensions and fix permissions on them. Should work after that. I have two copies technically one in /S/L/E and one in /E/E.

The T420's processor and graphics card isn't fully supported on Snow Leopard (although in theory it should still boot). However, you can install Mountain Lion directly. Tonymacx86 has directions and prebuilt installers for making a bootable drive out of your Mac App Store or store.apple.com purchase.

i update my pack to be closer to tluck's one (post 117)
differences are :
- FakeSMC.kext (cos no park @boot)
- dsdt.aml that i can't update to have sound even withe the advices i received) all others mods are ok

i add
SleepEnabler.kext and VoodooSDHC.kext the last AppleIntelE1000e.kext
and use genuine AppleHDA
---
i use old AppleIntelE1000e.kext (not 2.0 version cos for unknown reason ethernet doesn't work with 2.0)

my T420 works (battery indicator ok, ethernet ok, usb and cam ok) my system is up to date all updates done
10.8.2_ supplemental updates

find my pack in my signature (not as great as tluck pack but better than nothing

Update oct 8th

Hey guys for those with a nvidia Quadro 4200m you can get a partial fix by instaling the Nvidia 4xx/5xx support from the ##### (or atleast open CL),

Dont know if its right or not but on system specs I've found nvidia nvs on t420/520 not connected to any video outs on laptop and use HD3000 to out video. But if it has gpu switch option in bios like W520 has I think its possible to use it with nvidia card... otherwise not big difference between NVS and HD3000 in this case, maybe only if you need some cuda capabilities it may help a bit

ive disabled my Hd 3000 in my Bios so it only runs my Nvs quadro, like i said the patch makes Open CL work, but i guess it lacks complete hardware acceleration (chess wont work), we might be able to get the full QE/CI by using a modified fermi kext

NVS4200 is fermi card so to get it working you need to add id of your card to NVDAGF100Hal.kext and reboot, in log on boot you should see GF100HAL loaded or something like this... and top bar in osx should be transparent

this method worked for gts450 fermi too on my desktop

Great! In this case it's possible to make universal patch to enable this feature on all thinkpads lineup
