Please bring back swappable laptop batteries.

This is the new Dynabook Portégé Z40L-N, and it’s not quite what I’m asking for — while it does unusually have its own dedicated compartment, this 56Wh battery is more user-serviceable than swappable. Some other laptops offer that too. But what if you could carry a second battery with you, charge it outside of the laptop (maybe integrated USB-C), then toollessly swap at a moment’s notice?

Or are external batteries just better for that now?

The Portege Z40L-N offers a “self-replaceable battery.”
