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.

Dell Precision Mobile Workstation M20 Quick Reference Guide 9

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

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

www.dell.com | support.dell.com

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.

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.

Dell Precision Mobile Workstation M20 Quick Reference Guide 11

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

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

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 lowbattery alarms, see your

User’s Guide

for more information about the battery operating time.

User’s Guide

12 Dell Precision Mobile Workstation M20 Quick Reference Guide

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

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.

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

connected to an electrical outlet.

If the computer is connected to a docking device (docked), undock it. See the documentation that came with your docking device for instructions.

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.

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.
