Removing the Computer Access Panel
To access internal components, you must remove the access panel:
1. Remove/disengage any security devices that prohibit opening the computer.
2. Remove all removable media, such as optical discs or USB flash drives, from the computer.
3. Turn off the computer properly through the operating system, then turn off any external devices.
