Working on Your Computer

Before Working Inside Your Computer

Use the following safety guidelines to help protect your computer from potential damage and to help to ensure your

personal safety. Unless otherwise noted, each procedure included in this document assumes that the following

conditions exist:

• You have read the safety information that shipped with your computer.

• A component can be replaced or--if purchased separately--installed by performing the removal procedure in

reverse order.

WARNING: Disconnect all power sources before opening the computer cover or panels. After you finish working

inside the computer, replace all covers, panels, and screws before connecting to the power source.
