Changing the main battery
When your main battery has run out of power, you have two
options: plug in the AC adaptor or install a charged main battery.
Never short circuit the battery pack by either accidentally or
intentionally bringing the battery terminals in contact with another
conductive object. This could cause serious injury or fire, and could
also damage the battery pack and computer.
❖ Never expose a battery pack to abnormal shock, vibration or
pressure. The battery pack's internal protective device could
fail, causing it to overheat or ignite, resulting in caustic liquid
leakage, or explosion or fire, possibly resulting in death or
serious injury.
TECHNICAL NOTE: To avoid losing any data, save your files and
then either completely shut down your computer or put it into
Hibernation mode before changing the main battery.
Removing the battery from the computer

1 Save your work.

according to the instructions in “Using and configuring
Hibernation mode” on page 69.
