I have a ThinkPad T450 with a built-in and external batteries. Is there a setting in the BIOS or in the Lenovo suite of software where one could set how the batteries behave when they're being used? I'd like for the external battery to drain first so that I could then switch it for a different one before using the internal one. It's always easier to replace the external battery vs. having to remove the bottom case entirely to access the internal one.
