Open the display to a 90 degree angle. Rest the trackpad face down on the work surface and allow the display to hang over the edge. If possible, adjust your chair or work surface height so the display will rest on your legs and the upper case will lie flat on the work surface. If you cannot make this adjustment, you can remove the display with the screen closed. We recommend removing the display with the screen open in order to avoid changing the position of the hinges once the display has been removed.
