There is a very tiny button that I have heard you press to reset.
There is a very tiny button that I have heard you press to reset the system to prepare for a new battery.
On my T480 it's a few inches away from the external battery gold contact pins. What I don't know is when do you press it and for how long.
Most videos i find are not for T480s but they all seem to say hold this button for 15-30 seconds. any idea if you do this with both batteries installed or just the internal or both batteries removed.
I can't seem to find definitive information on what to do. Once i changed my internal battery, Windows now says that the external battery is not present when i know it is installed properly.
