in the stand with the securing button on the side of the cover and aligning the captive
screw in the stand with the screw hole in the cover.
When the stand is in place, tighten the thumbscrew.
Rotate the computer so that the stand is at the bottom and the drives are at the top.
To remove the stand:
Turn the computer over so that the stand is at the top.
