CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your

computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.

CAUTION: A new battery can explode if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the

manufacturer. Discard used batteries according to the manufacturer's instructions.

inserted between the battery and the socket before you attempt to pry out the battery. Otherwise, you may damage the system board by prying off

the socket or by breaking circuit traces on the system board.

NOTICE: To avoid damage to the battery connector, you must firmly support the connector while installing or removing a battery.
