Opening the Small Mini-Tower Computer Cover
NOTICE: To prevent damage to the system board, open the cover until it catches at a 45-degree angle. Then remove the optical drive
data cable and/or the hard drive data cable from the system board and open the cover to a 90-degree angle.
Opening the Small Mini-Tower System to a 45-Degree Angle
To close the computer cover, perform the following steps:
1. Check all cable connections, especially those that might have come loose during your work. Fold cables out of the way so that they do not
catch on the computer cover. Make sure cables are not routed over the drive cage —they will prevent the cover from closing properly.
2. Check to see that no tools or extra parts are left inside the chassis.
3. On the small mini-tower system, close the cover to a 45- degree angle and connect the optical drive data cable.
4. Close the system cover by pivoting the cover down toward the back of the system and into position. Make sure that the release buttons click
into place.
5. If you are using a padlock to secure your system, reinstall the padlock.
