AC Adapter: Dell™Latitude™CS/CS

Portable Computers User's Guide

Using the AC Adapter

The AC adapter converts AC power to the DC power required by the computer. The AC adapter kit includes the AC adapter with its attached DC

cable (which inputs power to the computer) as well as an AC power cable that connects to an electrical outlet.

You can connect the AC adapter with your computer either turned on or off.

The AC adapter works with electrical outlets worldwide. However, power connectors vary among countries. Before you use AC power in a foreign

country, you may need to obtain a new power cable designed for use in that country.

If the computer is docked to one of Dell's C/Port Family Advanced Port Replicators (APR) or C/Dock Family Expansion Stations, it obtains power

through the APR or expansion station, which must be connected to an electrical outlet.

Connecting the AC Adapter

1. ConnecttheACadapter'sattachedcableintothecomputer'sACadapterconnector(seeFigure 1).

2. Plug the AC power cable into the other end of the AC adapter.

3. Plug the AC power cable into an electrical outlet.

Turning On the Computer

NOTE: If you are running your computer on AC power with a battery installed, the AC adapter charges the battery (if needed) and then

maintains the battery's charge.

NOTICE: The AC adapter should be in a ventilated area, such as on a desktop or on the floor, when used to power the computer or

charge the battery. Do not use the AC adapter in a poorly ventilated environment, such as inside a carrying case.

Experimenting With Power Conservation

In general, the lower the value you set for each power conservation feature, the longer the battery's charge lasts. On the other hand, setting high

values tends to optimize the computer's performance.

To evaluate the way that different settings affect how long you can operate the computer on battery power versus the relative efficiency of how the

software performs, experiment as follows:

l Use the computer with all the options set at their default values.

l Use the computer with all the options disabled or set to Off.

l Use the computer with all the options set to their minimum or maximum values.

Using Key Combinations

Table 1 identifies the power management key combinations.
