CAUTION:

The battery is a lithium ion battery. To avoid possible explosion, do not

burn. Exchange only with the IBM-approved part. Recycle or discard the

battery as instructed by local regulations. In the United States, IBM has a

process for the collection of this battery. For information, call 1-800-426-

4333. Have the IBM part number for the battery unit available when you

call. (C007)

Protecting against Electrostatic Discharge – Static electricity can

harm delicate components inside your computer. To prevent static

damage, discharge static electricity from your body before you touch any

of your computer’s electronic components, such as the microprocessor.

You can do so by touching an unpainted metal surface, such as the

metal around the card-slot openings at the back of the computer.

As you continue to work inside the computer, periodically touch an

unpainted metal surface to remove any static charge your body may

have accumulated. In addition to the preceding precautions, you can also

take the following steps to prevent damage from electrostatic discharge:

•When unpacking a static-sensitive component from its shipping

carton, do not remove the component from the antistatic packing

material until you are ready to install the component in your

computer. Just before unwrapping the antistatic packaging, be sure

to discharge static electricity from your body.

•When transporting a sensitive component, first place it in an

antistatic container or packaging.

•Handle all sensitive components in a static-safe area. If possible, use

antistatic floor pads and workbench pads.
