All Fujitsu Lifbooks I had in the last 10 years have another setting. They do not start to charge the battery if the are more then about 95% charged. So there is no need to take the battery out while working "on cable power". I often see somehing like "97% full, not charging"

That's a battery longevity feature and not a safety feature, though. Any consumer electronics device should be safe to charge to 100% and be left plugged in.

You can do this on the Dell XPS series laptops, as well as the (older?) Sony Z-series.

I have my Dell set to start battery charge at 75% and stop at 85%.

The XPS line also tries to detect what to do based on usage patterns. Neat BIOS feature.
