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.

power button

10 Dell Precision Mobile Workstation M20 Quick Reference Guide

www.dell.com | support.dell.com

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.

Dell Precision Mobile Workstation M20 Quick Reference Guide 11

In addition, when your computer is connected to a docking device (docked), the

Battery Meter

window includes a

Dock Battery

tab, which displays the charge level and current status of the

docking device battery.

The following icons appear in the

Battery Meter

window:

For more information about QuickSet, right-click the icon in the taskbar, and click

Help

.

Microsoft

®

Windows

®

Power Meter

The Windows Power Meter indicates the remaining battery charge. To check the Power Meter,

double-click the icon on the taskbar. For more information about the

Power Meter

tab, see

your

User’s Guide

.

If the computer is connected to an electrical outlet, a icon appears.

Charge Gauge

Before you insert a battery, press the status button on the battery charge gauge to illuminate the

charge-level lights. Each light represents approximately 20 percent of the total battery charge. For

example, if the battery has 80 percent of its charge remaining, four of the lights are on. If no lights

appear, the battery has no charge.

• The computer or docking device is running on battery power.

• The battery is discharging or idle.

• The computer or docking device is connected to an electrical outlet and

running on AC power.

• The battery is charging.

• The computer or docking device is connected to an electrical outlet and

running on AC power.

• The battery is discharging, idle, or charging.

12 Dell Precision Mobile Workstation M20 Quick Reference Guide

www.dell.com | support.dell.com

Health Gauge

The battery operating time is largely determined by the number of times it is charged. After

hundreds of charge and discharge cycles, batteries lose some charge capacity, or battery health. To

check the battery health, press and hold the status button on the battery charge gauge for at least 3

seconds. If no lights appear, the battery is in good condition, and more than 80 percent of its

original charge capacity remains. Each light represents incremental degradation. If five lights

appear, less than 60 percent of the charge capacity remains, and you should consider replacing the

battery. See your

User’s Guide

for more information about the battery operating time.

Low-Battery Warning

NOTICE: To avoid losing or corrupting data, save your work immediately after a low-battery warning.

Then connect the computer to an electrical outlet, or install a second battery in the module bay. If the

battery runs completely out of power, hibernate mode begins automatically.

A pop-up window warns you when the battery charge is approximately 90 percent depleted. For

more information about low-battery alarms, see your

User’s Guide

.

A low-battery warning occurs when the battery charge is approximately 90 percent depleted. The

computer beeps once, indicating that minimal battery operating time remains. During that time,

the speaker beeps periodically. If two batteries are installed, the low-battery warning means that the

combined charge of both batteries is approximately 90 percent depleted. The computer enters

hibernate mode when the battery charge is at a critically low level. For more information about low-

battery alarms, see your

User’s Guide

.

Dell Precision Mobile Workstation M20 Quick Reference Guide 13

Charging the Battery

NOTE: The AC adapter charges a completely discharged battery in approximately 1 hour with the

computer turned off. Charge time is longer with the computer turned on. You can leave the battery in the

computer as long as you like. The battery’s internal circuitry prevents the battery from overcharging.

When you connect the computer to an electrical outlet or install a battery while the computer is

connected to an electrical outlet, the computer checks the battery charge and temperature. If

necessary, the AC adapter then charges the battery and maintains the battery charge.

If the battery is hot from being used in your computer or being in a hot environment, the battery

may not charge when you connect the computer to an electrical outlet.

The battery is too hot to start charging if the light flashes alternately green and orange.

Disconnect the computer from the electrical outlet and allow the computer and the battery to cool

to room temperature. Then connect the computer to an electrical outlet to continue charging the

battery.

For more information about resolving problems with a battery, see your

User’s Guide

.

Removing a Battery

CAUTION: Before performing these procedures, disconnect the modem from the telephone wall jack.

For information about removing the second battery, see your

User’s Guide

.

NOTICE: If you choose to replace the battery with the computer in standby mode, you have up to 1

minute to complete the battery replacement before the computer shuts down and loses any unsaved

data.

1

Ensure that the computer is turned off, suspended in a power management mode, or

connected to an electrical outlet.

2

If the computer is connected to a docking device (docked), undock it. See the documentation

that came with your docking device for instructions.

3

Slide and hold the battery-bay (or module-bay) latch release on the bottom of the computer,

and then remove the battery from the bay.

For information about installing the second battery, see your

User’s Guide

.

Storing a Battery

Remove the battery when you store your computer for an extended period of time. A battery

discharges during prolonged storage. After a long storage period, charge the battery fully before you

use it.
