I have tried searching everywhere and can't seem to find any solution to this problem. Recently, I ordered a backlit keyboard for my Dell E5440 laptop. I installed it just fine and the backlight works, but the pointstick in the middle of the keyboard is not functioning. I have installed Dell System Manager to control the backlit settings but I can't find anything about how to make the point stick work. Does anyone know how I can fix this issue? Thank you in advance.
Did you ever get this resolved because I am having the exact same issue. Had unlit keyboard and replaced with lit keyboard, and the pointstick does not work.
