Setting Up Your Computer

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the

Product Information Guide.

Unpack the accessories box.

Set aside the contents of the accessories box, which you will need to complete the setup of

your computer.

The accessories box also contains user documentation and any software or additional

hardware (such as PC Cards, drives, or batteries) that you have ordered.

outlet.

Dell Precision Mobile Workstation M20 Quick Reference Guide 9

Open the computer display and press the power button to turn on the computer.

NOTE: Do not connect the computer to the docking device until the computer has been turned on and

shut down at least once.

Battery Performance

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions

located in the Product Information Guide.

NOTE: Batteries for portable computers are covered only during the initial 1-year period of the limited

warranty for your computer. For more information about the Dell warranty for your computer, see the

Product Information Guide or separate paper warranty document that shipped with your computer.

For optimal computer performance and to help preserve BIOS settings, operate your Dell™

portable computer with the main battery installed at all times. Use a battery to run the computer

when it is not connected to an electrical outlet. One battery is supplied as standard equipment in

the battery bay.

NOTE: Battery operating time (the time the battery can hold a charge) decreases over time. Depending

on how often the battery is used and the conditions under which it is used, you may need to purchase a

new battery during the life of your computer.

Battery operating time varies depending on operating conditions. You can install an optional

second battery in the module bay to significantly increase operating time. For more information

about the second battery, see your

User’s Guide

Operating time is significantly reduced when you perform operations including, but not limited to,

the following:

• Using optical drives, such as DVD and CD drives

• Using wireless communications devices, PC Cards, or USB devices

• Using high-brightness display settings, 3D screen savers, or other power-intensive programs

such as 3D games

• Running the computer in maximum performance mode

NOTE: It is recommended that you connect your computer to an electrical outlet when writing to a CD or

DVD.

You can check the battery charge before you insert the battery into the computer. You can also set

power management options to alert you when the battery charge is low.

CAUTION: Using an incompatible battery may increase the risk of fire or explosion. Replace the

battery only with a compatible battery purchased from Dell. The lithium-ion battery is designed to work

with your Dell computer. Do not use a battery from other computers with your computer.

CAUTION: Do not dispose of batteries with household waste. When your battery no longer holds a

charge, call your local waste disposal or environmental agency for advice on disposing of a lithium-ion

battery. See "Battery Disposal" in the Product Information Guide.

CAUTION: Misuse of the battery may increase the risk of fire or chemical burn. Do not puncture,

incinerate, disassemble, or expose the battery to temperatures above 65°C (149°F). Keep the battery

away from children. Handle damaged or leaking batteries with extreme care. Damaged batteries may

leak and cause personal injury or equipment damage.

Checking the Battery Charge

The Dell QuickSet Battery Meter, the Microsoft

Windows

Power Meter

window and icon,

the battery charge gauge and health gauge, and the low-battery warning provide information on the

battery charge.

For more information about checking the charge on the second battery, see your

User’s Guide

Dell™ QuickSet Battery Meter

If Dell QuickSet is installed, press <Fn><F8> to display the QuickSet Battery Meter.

The

Battery Meter

window displays status, charge level, and charge completion time for the battery

in your computer.

NOTE: You can use your docking device to charge a computer battery. However, a battery in a docking

device does not power the docking device or computer.
