Preventing static electricity discharge
Warning
To avoid exposure to dangerous
electrical voltages and moving parts,
turn off your notebook, remove the
batteries, and unplug the power cord,
modem cable, and network cable before
opening the case.
Warning
To prevent risk of electric shock, do not
insert any object into the vent holes of the
notebook.
Important
Before performing maintenance on the
notebook, you should read and
understand the information in this
section.
The components inside your notebook are extremely sensitive to static
electricity, also known as
electrostatic discharge
(ESD).
Before performing maintenance on the notebook, follow these guidelines:
■
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.
■
Always hold components by their edges. Avoid touching the edge
connectors. Never slide components over any surface.
■
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.
Tape
Some of the procedures in this guide involve removing tape that holds cables
or components. Two types of tape are used in this Gateway notebook:
■
Mylar, non-conductive tape is typically transparent, with a red or brown
tint.
■
Conductive tape is typically grey or silver.
If the existing tape cannot be reused, replace it with the same type
(conductivity) of tape. Both types of replacement tape should be non-ESD
generating tape.
Do not use cellophane tape
Preparing the notebook
To prepare the notebook for maintenance:
1
Make sure that the disc drive is empty.
2
Turn off the notebook.
3
Disconnect from the optional port replicator. For more information, see
“Disconnecting from the port replicator” on page 6
4
Disconnect the AC adapter, modem cable, and network cable if they are
connected to the notebook.
5
Disconnect all peripheral devices connected to the notebook and remove
any PC cards.
