Reminds me of the “X62” mod I did a couple years ago. It was quite expensive all said and done but was so satisfying upgrading the X61 to a sharp screen and new motherboard
I picked up an x62 complete system and its been fantastic. I dont use it as much as I should, but I love the feeling I get booting it up. Its very unique in the collection of thinkpads I have amassed over the years.
Have you ever found a good battery replacement? The battery life was always the biggest weakness
I ended up getting the extended battery that hangs over the back a little bit. It was a new in 2018. I have not looked since.
