  1. [GUIDE] Thinkpad T420 with (Mountain) Lion

    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.
  2. [GUIDE] Thinkpad T420 with (Mountain) Lion

    I have been reading through this thread and the attached links for the past week working on my new Lenovo T420 with Mountain Lion 10.8.2 and think I may have finally stumbled across a solution for the LVDS display and the artifacts and ring stalls. Check the post below to see how you can use SwitchResX to create a custom resolution profile. http://www.tonymacx86.com/hp-probook-4530s/33113-hp-probook-4730s-17.html#post379880 I have tried many different things to fix the Intel HD 3000 AppleIntelSNBGraphics kext artifacts and glitches and this has been the best solution I have found so far that works for me. Changing the custom connectors or using the patched AppleIntelSNBGraphics.kext did not seem to work. They reduced the number of artifacts but did not get rid of them and the laptop was mostly unusable, I was about ready to give upon it. I tried different versions of FakeSMC, editing my own DDST, etc. Basically, just go to System preferences - Display - Color - Create new Calibrated Display, name it Custom Calibrated Display. Then Install SwitchResX and create a custom resolution profile, apply it and then reboot, afterwards the graphics glitches are gone.
