You neglected something important in step 1. The t450s has 2 batteries, 1 removable and another built in. To do repair work you MUST first reboot to the bios setup and disable the built-in battery in addition to removing the outboard battery.
Also you neglect to mention that the radio adapter has a dual function, wifi and bluetooth; also the bios has a whitelist of acceptable radio cards and it can be difficult to find a replacement.
Also, the screws holding the bottom casing on are phillips head and are screwed into soft plastic, some of the heads being deeply recessed. A phillips head screwdriver will not seat on the head without at least a bit of pressure, so the last turn or two with the screw almost out cannot take the screw out, instead it’s just forced back into the plastic. And with a deep recess, it’s VERY hard to pull the screw out completely.
