DO NOT WASTE YOUR TIME WITH THIS GUIDE. I am a certified repair technician and there is absolutely zero reason to disassemble the system and remove the motherboard for a panel swap. You can simply disconnect the antenna cables and EDP connectors; open the laptop and hang the LCD assembly over the edge of a table; then remove the hinge screws and lift it off. Nearly all ThinkPad models are like this. Please read the Hardware Maintenance Manual on the Lenovo support site for the correct way to do this. Page 93: https://download.lenovo.com/pccbbs/mobil...
