Battery Packs

Using a New Battery Pack

Charge the installed battery pack while connected to an external power source.

A new battery pack should be fully charged before it is used for the first time. The battery pack will work without being fully charged, but the battery gauge will not show an accurate charge until the battery pack receives its first full charge.

Replacing the Primary Battery Pack

You can resolve a low-battery condition by replacing a discharged battery pack.

ÄCAUTION: If you are removing a battery pack that is the only power source available to the system while the computer is on, connect the computer to another power source before removing the battery pack. Failure to do so will result in loss of information. If the computer is on and connected to more than one power source, you can remove a battery pack.

1.If the battery pack in the battery compartment is the only power source, connect to the computer to an external power source such as the AC adapter.

2.Close the display and turn the computer bottom side up.

3.Slide the battery security latch to the unlock icon position 1.

4.To remove the battery pack, slide and hold the battery release latch 2 to the right. The battery will disconnect.

5.Use the notch to lift the battery pack from the compartment 3.
