Figure 4-2. Computer Cover Removal
To remove the computer cover, follow these steps:
1. Turn off power to all peripherals, and disconnect the AC power cable
from its AC outlet.
2. Remove the padlock if one is installed.
3. Press in on the two securing buttons until the cover is free to swing up.
4. Raise the back of the cover, and pivot it toward the front of the
computer.
5. Lift the cover off of the hooks at the front of the chassis.
Three plastic hooks on the inside-front part of the cover secure it to the
chassis.
Before you reinstall the cover, fold all cables out of the way so that they do not
interfere with the cover or with proper airflow inside the computer.
