Changing the 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.
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.
When your main battery has run out of power, you have two
options: plug in the AC adapter or install a fresh battery.
TECHNICAL NOTE: To avoid losing any data, save your files
and then either completely shut down your computer, or put it
