These are the instructions I'm using to reset the mobo type/serial and generate a UUID. I was then able to boot from the USB and bring up the HDM menu like you'll see near the middle of this page-which is super helpful but requires translation. However, I found a source for HDM v1.90, installed it, and was able to use the included executable to create a bootable USB stick. Reading about the software side of the replacement was not encouraging since most of what I found on the internet seems like it's from a time when the Lenovo HDM had to be on a real floppy disk. I think I have a handle on physically getting it in there, but keying-in the HDM stuff to get it to work right is worrying me. So I've disassembled my Thinkpads to replace thermal paste but this is my first mobo replacement.

A can of compressed air may be useful too, and a bottle of isopropyl alcohol and cotton buds are good for cleaning, but not on the screen. The only tools you need for servicing a ThinkPad are a set of small screwdrivers and a nylon spudger (for taking the screen and keyboard bezels off), and possibly a pair of tweezers. Corporate bulk purchasers don't usually go for it. Not only will it have better brightness, colour, contrast and viewing angles - you will most probably more than make up the investment when selling it. When buying a new ThinkPad, consider taking the IPS screen option if possible, as it doesn't cost much.
When buying a used ThinkPad, remember to check that the BIOS is not locked with a supervisor's password and that Computrace is not enabled and activated.
