Hi guys and gals just thought i would give my experiance with the Latitude E6420. i have been using unifail install method with a 10.7.2 retail, building the external bootable usb easy as pie, install's perfectly after install you need boot with the usb pluged in so you have a boot menu after you have selected the drive that you have installed Lion on you then need the multifail 4.1 package installer to install chimera (chameleon, stolen and rebranded) or you can use chameleon bootloader up to you but install nullcpu and fakesmc kext's to boot otherwise it throws up a panic. after install i used easybeast install and most hardware detected what is working Processor: i7 2720qm (detected all cores) Ram 8GB Hard drive only working in ahci Audio/Mic install Voodoo Hda 2.7.3 but only works with dsdt but we will get to that later Graphics detects 1024x768 Battery/Adapter Voodoo Battery not working with dsdt Usb works out the box but can cause panic and crashing so use iousb rollback and it starts working perfectly webcam not working right now is the bit which im scratching my head on and need some help with the dsdt if you use this dsdt ThinkPad T420 the graphics work perfectly hdmi out works vga out works but it causes cpu overheating stops voodoo battery from working and stops the fn key from working so have to turn down brightness from display settings so not helpful at all i tried to edit the dsdt with no luck what i want to do it strip out the nvidia part of the dsdt and just test that first but i dont have the know how. i will do some more testing today and report back
