And it is much harder to buy BGA processors than just normal PGA processors: pretty much no one would take out the BGA processor from their laptop and just sell that, and it is pretty hard to buy new old stock BGA processors. The X61, on the other hand, has the processor soldered down on to the board, making it harder to replace the processor.

Or if one wants to use newer FSB 1066 processors or even quad-core processor, BIOS mod and motherboard mod are available to allow the processor to run on the T61 motherboard.

It is quite common to replace the processor in T61s, just buy a new processor, install that on to the motherboard, done. Unless the processor can be replaced or upgraded. If the machine is an X61s, then the 65 nm processor is pretty much the only choice. Most of the listings online come with a T7100 or T7300 processor, built with a 65 nm process.

However, when buying used, especially in 2020, it is really hard to pick one specific processor. X61 comes with various CPU options available when buying new: The thing that never changed is the processor: the 65nm Core 2 Duo L7500. Many of the components have been upgraded since then, 2GB DDR2 is upgraded to 6GB, 160GB spin drive has been replaced by a 512GB SSD, and the TN screen has been replaced with an AFFS (IPS) screen. I bought my X61s used in 2010 (I simply couldn't afford it back in 2007 when it first came out) and keeps using it as my main laptop (I have a much more powerful desktop PC for most of the stuff though). ThinkPad X61 is a classical machine, along with T61 they are the last 4:3 ThinkPads made by Lenovo.
