After a long journey, both batteries in my T450s were flat, and this morning when I plugged in and booted up I got the message that "The battery installed is not supported by this system and will not charge". True to its word, one of the batteries does not seem to be charging. These are the original batteries which came with the laptop when bought new from Lenovo. They have performed well since I received it, no problems to date, and no obvious reduction in performance. How can I get the battery charging again?
Thanks for your help.

I've been playing with it a bit, and can confirm that this is the external, removable battery, rather than the internal battery.
