There is a small switch near the T440s external battery. What is it for?
-
There is a corresponding hole in the bottom cover, right?
If that is the case, then it is the reset button that you can push with a paper clip since you cannot easily unplug the internal battery. -
No, it is not the microswitch near the internal battery, which disconnects the internal battery if pushed down. Any other ideas?
-
Have you checked the Hardware Maintenance Manual for the T440s?
-
I guess it's responsible for switching from the external to the internal battery when you remove the external battery.
