Always observe the following precautions before you install a

computer component:

1. Do not remove a component from its protective

packaging until you are ready to install it.

2. Wear a wrist grounding strap and attach it to a metal

part of the computer before handling components. If a

wrist strap is not available, maintain contact with the

computer throughout any procedure requiring ESD

protection.

Required tools

In performing the component replacement process, you will

need the following tools:

•Philips screwdriver

•Hex screwdriver

•Flat screwdriver

•Scissors

Note

The screws for the different components vary in size. During the

disassembly process, group the screws with their corresponding

components to avoid mismatches when putting back the components.
