In this video I am going to talk about how I upgraded my ThinkPad X61, probably more than 10 years too late.

The details of BIOS modding and SPD modding could be found on my blog: https://www.zephray.me/post/x61_cpu_u...

The TLD3 LED driver board for X61, redrew with KiCad could be found on my GitHub: https://github.com/zephray/X61-Backli...

The PGA-BGA interposer PCB design could also be found on my GitHub: https://github.com/zephray/Pants479
