Battery operating time varies depending on operating conditions. Operating time is significantly reduced when you perform operations including, but not limited to, the following:

• Using optical drives.
• Using wireless communications devices, Express Cards, memory cards, or USB devices.
• Using high-brightness display settings, 3D screen savers, or other power intensive programs such as complex 3D graphics applications.
• Running the computer in maximum performance mode (see “Power Management Modes” on page 56 for information about accessing Windows Power Options Properties or Dell Quick Set, which you can use to configure power management settings).

Using Express Cards

Express Cards provide additional memory, wired and wireless communications, multimedia and security features. For example, you can add an Express Card to make wireless wide area network (WWAN) connectivity available on your computer

Express Card Blanks

Your computer shipped with a plastic blank installed in the Express Card slot. Blanks protect unused slots from dust and other particles. Save the blank for use when no Express Card is installed in the slot; blanks from other computers may not fit your computer.

Installing a Memory Card

You can install a memory card in the computer while the computer is running. The computer automatically detects the card. Memory cards are generally marked with a symbol (such as a triangle or an arrow) or a label to indicate which end to insert into the slot. The cards are keyed to prevent incorrect insertion. If card orientation is not clear, see the documentation that came with the card.
