Your computer can be configured to warn you when the battery is running low. For more information, see “Setting battery alarms” in the electronic user’s guide.
Changing the main batteryWhen your main battery has run out of power, you have two options: plug in the AC adapter or install a fresh 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.
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.
