Yes. Many ThinkPads had a small internal battery to power it when you were swapping the main battery.

- ProAm 8y agoThat is awesome, I had no idea. Dumb question, do you know what the feature is called, just hot-swappable capable or something for when Im shopping?
- snazz 8y ago“ThinkPad Internal Battery” works on Google.
- cr0sh 8y agoHeh - my TRS-80 Model 100 has that feature: A small NiCad (though I'll be swapping it with a newer super capacitor soon) keeps the memory contents available when you swap out the four AA batteries if they run low (you get several days of runtime off them).
