I recently busted out my old ThinkPad T40, the last of the OG IBM ThinkPads. I picked it up some time around my university days because I liked collecting ThinkPads at the time, and it was a nice complement to my existing ThinkPad T60 and T430. 20 years difference, but they still look similar. The battery is dead, but everything else still works. Checking a few online listings, I’m surprised that I can still find batteries sold for this model. Probably old stock that’s been sitting around...
