Hey guys, its been awhile since ive been on here lol, which is kinda a good thing because I haven't been having any issues with my computers. Well, until now. I recently grabbed my T420 Thinkpad that I haven't powered up in 5 months and was going to use it. I open it up and lo and behold theres a crack going across the screen and a giant black blotch going along with that crack.... so yeah I need a new screen.. is it pretty straight forward swapping out a screen on these? My dad has 2 L420s sitting at his place and I can use one for parts if I wished... just wondering if their parts compatible. Thank guys.
