Step 1: Install Touchpad Module
Place the Touchpad Module flat, slightly below the Keyboard as shown.
Like the Keyboard, you can confirm it is properly aligned by lining it up to the dashed lines on the Mid Plate.
Applying gentle downward pressure to keep the Touchpad module flat, slide it up into place.
Remember that the Input Deck Latches should still be open at this point, otherwise the Touchpad Module won't slide on.
The Touchpad Module can be installed either directly below the Keyboard or offset by one space to the right. For example, the Keyboard can have the Touchpad below it, or the Keyboard can be left-aligned while the Touchpad is centered.
