							Removing and Replacing Parts 4-17
To remove a tilt-support foot, follow these steps:
1. Close the display assembly.
2. With the foot set to its fully retracted position, insert a small device 
(such as a scribe) into the bottom notch on the foot-retaining screw 
cover and gently lift out the cover partway. Lift on the sides of the 
cover, working around to the top, and then lift out the cover.
3. Remove the foot retaining screw.
The foot retaining screw also functions as a mounting screw for one of the 
display assembly hinges, which has a threaded hole for the screw. 
Therefore, the foot retaining screws cannot be reinstalled with the display 
assembly removed.
The foot-retaining screw cover can fit only one way in the foot. To reinstall 
the cover, make sure the tilt-support foot is in its fully retracted position. 
Then orient the cover with the notch toward the bottom of the computer and 
its mounting tab toward the top of the computer. Press in on the cover until 
it snaps into place.
