About the Batteries

Your computer includes a 4-cell or 6-cell lithium ion battery that provides power when an electrical outlet is not available. The battery is installed on the underside of the computer and forms part of the bottom of the computer. Lithium ion batteries are longer lived than conventional batteries and do not require replacement as often. You do not need to drain a lithium ion battery completely before recharging it.

Do not place spent batteries with common household waste products. See Battery Disposal for more information.

Keep the following information in mind when you are running your computer from the battery:

A fully charged 6-cell, 34-watt-hour (WH) battery provides approximately 2 hours of battery life; a fully charged 4-cell, 23-WH battery provides approximately 1 hour of battery life. Actual performance varies, depending on which power management features are enabled and which application programs you are using.

The integrated battery charge gauge lets you check the charge status of an installed or uninstalled battery at any time.

The battery’s self-test capability alerts you to battery conditions such as low charge.
