123 Mobile Computing Changing batteries Changing batteries 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 main battery. 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 To remove the battery: 1 Save your work. 2 Power off the computer or place it in Hibernation mode according to the instructions in "Using Hibernation" on page 106. 3 Unplug and remove any cables connected to the computer, including the AC adapter. 4 Close the display panel and turn the computer upside down with the front of the computer facing you.
