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.

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.
