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

To remove the battery:

1 Save your work.

2 Turn off the computer or place it in Hibernation mode

according to the instructions in “Using and configuring

Hibernation mode” on page 81.

3 Unplug and remove any cables connected to the computer,

including the AC adaptor.

4 Close the display panel and turn the computer upside down.

Before you turn the computer over, make sure that the computer

display is properly closed and is not in tablet mode. Setting the

computer down on the display may cause damage to the screen.
