Thinkpads offer a way to limit the percent State of Charge (SoC) while charging. AFAIK this is the only laptop which does so.
I do this manually by removing the battery from my laptop once it reaches 70-90% SoC (and I'm plugged in, obviously). This is superior for battery protection because the temperature is limited to room temperature, but inferior because the laptop shuts off on power loss.
- teaspoon 16y agoAre the battery life savings really worth the hassle and potential for lost work?
- icegreentea 16y agoSince I've picked up my Thinkpad, I really wonder why Lenovo doesn't stick in a small internal battery ontop of the removable (say good for like 10 minutes or something...) so that: a) On power loss (battery removed), it can still dump into hibernate (the real one) b) So you can hotswap the external batteries. I have two batteries, and when I'm out for long periods, it annoys me that I have to dump it into hibernate so I can swap batteries. It's just an extra few minutes that really annoy me.
