I own the above laptop. It has two rows of buttons, one row below the touchpad and one above (or below the space key, don't know if this row really belongs to the touchpad). In the latter row, i.e. the one above the TP, the middle button is not giving any event. The other row works as expected, all three buttons are working.
Any idea how to configure this correctly.
The middle button will either be a middle click, some sort of scroll, or a "lock" for the left click to make clicking and dragging easier.
