CAUTION: Before you begin this procedure, follow the safety instructions in the Product Information Guide.
NOTE: Place your computer on a soft surface to prevent scratching the top cover.
Your computer can be used in either a vertical or horizontal position.
To use the computer in a vertical position, you must attach the computer stand:
Place the computer on its right side so that the drive bays are at the bottom.
Fit the stand onto what was the left side of the computer:
Position the stand as shown in the following illustration by aligning the large round hole
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.
