4 Maintaining and Troubleshooting Your E-4200 System

Opening the case

The system is available in three basic models:
•
Desktop
•
Mid-tower
•
Tower
The desktop case has a removable top panel and a removable front bezel.
The mid-tower and tower cases have two removable side panels, and a
removable front bezel.
To install or remove components inside your desktop system, you must
remove the top cover panel. For some procedures you must remove the front
bezel. For the mid-tower and tower systems, you must remove the panel on
the right side (as seen from the back of the system). For some procedures
you must remove the left side panel and the front bezel.
Your system includes an anti-intrusion switch on the case. If you attempt to
open the case without turning off the system, your system automatically
turns off.
Because the components inside your computer are extremely sensitive to
static electricity, be sure to follow the precautions for avoiding static
electricity damage at the beginning of this chapter.
