It seems the ThinkBook 14 G7 ARP the uses chips like AMD Ryzen 7 7735HS, which have TDP of 35-54W and zen 3+ [1]. That would explain the fan noise and lack of battery life.

I'm think about going in the other direction, because my p14s (2023) screen is starting to feel too small for my old eyes and the battery life was never good. I think a Macbook Air upgraded to 32GB would provide enough speed, whilst having a better screen. There doesn't seem to be an X1-like Thinkpad that has a 15 or 16 inch screen that I can find. One problem is lenovo has so many product lines it takes in depth research to find what you're looking for. Has anyone tried newer AMD cpus in Thinkpads? My workflow is very linux oriented and my brain doesn't like the idea that I'll need to develop on mac and deploy to linux. That seems too risky to me and I don't need or want docker if I don't have to use it.
