Replacing the 802.11 Mini PCI card

This package includes a replacement 802.11 Mini PCI card for your Gateway notebook and these printed instructions.

Tools you need

You will need a small Phillips screwdriver to replace the 802.11 Mini PCI card.

The components inside your notebook are extremely sensitive to static electricity, also known as electrostatic discharge (ESD).

Caution ESD can permanently damage electrostatic discharge

sensitive components in your notebook. Prevent ESD damage by following ESD guidelines every time you open your notebook case.

Warning To avoid exposure to dangerous electrical voltages and

moving parts, turn off your notebook, remove the battery, and unplug the power cord and modem cable before opening the case.

Before replacing the 802.11 Mini PCI card, follow these guidelines:

■ Turn off your notebook power.

■ Remove the battery(ies) and unplug the power cord.

■ Disconnect all peripheral devices and remove any PC Cards.

■ Wear a grounding wrist strap (available at most electronics stores) and

attach it to a bare metal part of your workbench or other grounded connection.

■ Touch a bare metal surface on your workbench or other grounded object.

■ Avoid static-causing surfaces such as carpeted floors, plastic, and packing

foam.

■ Remove components from their antistatic bags only when you are ready

to use them. Do not lay components on the outside of antistatic bags because only the inside of the bags provide electrostatic protection.
