Storing a Battery
Battery Performance
NOTE: For 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. One battery is supplied as standard equipment in the battery bay.
NOTE: Because the battery may not be fully charged, use the AC adapter to connect your new computer to an electrical outlet the first time you use the
computer. For best results, operate the computer with the AC adapter until the battery is fully charged. To view battery charge status, place the mouse
cursor over the battery icon in the Windows notification area.
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.
NOTE: It is recommended that you connect your computer to an electrical outlet when writing to media.
Battery operating time varies depending on operating conditions. Operating time is significantly reduced when you perform operations including, but not
limited to, the following:
l
Using optical drives.
l
Using wireless communications devices, ExpressCards, media memory cards, or USB devices.
l
Using high-brightness display settings, 3D screen savers, or other power-intensive programs such as complex 3D graphics applications.
l
Running the computer in maximum performance mode (see Configuring Power Management Settings for information about accessing Windows Power
Options Properties or Dell QuickSet, which you can use to configure power management settings).
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 battery is designed to work with your Dell computer. Do not use batteries 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
You can check the battery charge on your computer using any one of the following methods:
l
Dell QuickSet Battery Meter
l
Microsoft Windows battery meter icon
l
Battery charge/health gauge located on the battery
l
Low-battery warning pop-up window
located in the notification area
Dell QuickSet Battery Meter
To view the Dell QuickSet Battery Meter:
l
or
Double-click the Dell QuickSet icon in the taskbar, and then click Battery Meter
l
Press <Fn><F3>
The Battery Meter displays the status, battery health, charge level, and charge completion time for the battery in your computer.
For more information about QuickSet, right-click the QuickSet icon, and then click Help.
Microsoft® Windows® Battery Meter
The battery meter indicates the remaining battery charge. To check the battery meter, double-click the
icon in the notification area.
Charge Gauge
By either pressing once or pressing and holding the status button on the battery charge gauge, you can check:
l
Battery charge (check by pressing and releasing the status button)
l
Battery health (check by pressing and holding the status button)
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. Therefore, a battery can show a status of charged, but maintain a reduced charge capacity (health).
Check the Battery Charge
To check the battery charge, press and release the status button on the battery charge gauge to illuminate the charge indicator 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
are on, the battery has no charge.
Check the Battery Health
NOTE: You can check battery health in one of two ways: by using the charge gauge on the battery, as described below, and by using the Battery Meter
in Dell QuickSet. For information about QuickSet, right-click the QuickSet icon in the notification area, and then click Help.
To check the battery health using the charge gauge, press and hold the status button on the battery charge gauge for at least 3 seconds to illuminate the health indicator lights. Each light represents incremental degradation. If no lights appear, the battery is in good condition, and more than 80 percent of its
original charge capacity remains. If five lights appear, less than 60 percent of the charge capacity remains, and you should consider replacing the battery (see Battery 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.
If the battery runs completely out of power, Sleep state begins automatically.
A pop-up window warns you when the battery charge is approximately 90 percent depleted. The computer enters Sleep state when the battery charge is at a critically low level.
You can change the settings for the battery alarms in Dell QuickSet or the Power Options window (see Configuring Power Management Settings).
Conserving Battery Power
To conserve battery power on your portable computer, do any of the following:
l
Connect the computer to an electrical outlet when possible; battery life is largely determined by the number of times the battery is used and recharged.
l
Configure the power management settings using either Dell QuickSet or Microsoft Windows Power Options to optimize your computer's power usage
(see Configuring Power Management Settings).
l
Use the Sleep power state when you leave the computer unattended for long periods of time (see Using the Sleep Power State).
Configuring Power Management Settings
You can use Dell QuickSet or Windows Power Options to configure the power management settings on your computer.
l
For information on how to use the Dell QuickSet Power Management wizard, right-click the QuickSet icon in the notification area, click Help, and then
select Power Management.
l
To use Windows Power Options, do one of the following:
l
Click Start
® Control Panel® Hardware and Sound® Power Options, and then select a power plan in the Select a power plan window.
or
l
Click the
icon in the notification area, click Power Options, and then select a plan in the Select a power plan window.
Using the Sleep Power State
Rather than shutting down your portable computer, use the Sleep power state to conserve power. Sleep automatically saves your work to your hard drive,
and then returns you to your previous work session without restarting your computer.
NOTICE: If your computer loses AC and battery power while in Sleep state, it may lose data.
To enter Sleep state:
l
Click Start
, click
, and then click Sleep.
or
l
Depending on how you set the power management options in the Windows Power Options or Dell QuickSet, use one of the following methods:
l
Press the power button.
l
Close the display.
l
Press <Fn><Esc>.
To exit Sleep state, press the power button.
Charging the Battery
NOTE: Charge time is longer with the computer turned on. You can leave the battery in the computer for 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

When a Dell™ computer is running on battery power, you can conserve power by setting the display brightness to the lowest comfortable level.
l
Press <Fn> and the up-arrow key to increase brightness on the integrated display only (not on an external monitor).
l
Press <Fn> and the down-arrow key to decrease brightness on the integrated display only (not on an external monitor).
NOTE: Brightness key combinations only affect the display on your portable computer, not monitors or projectors that you attach to your portable
computer or docking device. If your computer is connected to an external monitor and you try to change the brightness level, the Brightness Meter may
appear, but the brightness level on the external device does not change.
Switching the Video Image From Your Computer Display To a Projector

computer display or the external device.
Press <Fn><F8> to switch the video image between the display only, the external device only, or the display and the external device simultaneously.
Setting Display Resolution and Refresh Rate
NOTE: If you change the display resolution from the current settings, the image may appear blurry or text may be hard to read if you change the
resolution to one not supported by your computer and display. Before you change any of the display settings, make a note of the current settings so
you can change back to the previous settings if needed.
You can enhance the legibility of text and change the appearance of images on the screen by adjusting display resolution. As you increase resolution, items
appear smaller on the screen. In contrast, lower resolution causes text and images to appear larger and can benefit people with vision impairments. To
display a program at a specific resolution, both the video card and the display must support the program, and the necessary video drivers must be installed.
NOTE: Use only the Dell-installed video drivers, which are designed to offer the best performance with your Dell-installed operating system.
If you choose a resolution or color palette that is higher than the display supports, the settings adjust automatically to the closest supported values.
To set the display resolution and refresh rate for your display:
1.
Click Start
2.
Under Appearance and Personalization, click Adjust screen resolution.
® Control Panel.

Helpful Tips
l
Use Microsoft® Windows® Explorer to drag and drop files to a CD-R or CD-RW only after you start Roxio Creator and open a Creator project.
l
Do not burn a blank CD-R or CD-RW to its maximum capacity; for example, do not copy a 650-MB file to a blank 650-MB CD. The CD-RW drive needs 1–2
MB of the blank space to finalize the recording.
l
Use CD-Rs to burn music CDs that you want to play in regular stereos. CD-RWs do not play in most home or car stereos.
l
Music MP3 files can be played only on MP3 players or on computers that have MP3 software installed.
l
Use a blank CD-RW to practice CD recording until you are familiar with CD recording techniques. If you make a mistake, you can erase the data on the
CD-RW and try again. You can also use blank CD-RWs to test music file projects before you record the project permanently to a blank CD-R.
l
You cannot create audio DVDs with Roxio Creator.

Securing Your Computer
Dell™ Inspiron™ 1521 Owner's Manual Security Cable Lock
Passwords
If Your Computer Is Lost or Stolen
Security Cable Lock
NOTE: Your computer does not ship with a security cable lock.
A security cable lock is a commercially available antitheft device. To use the lock, attach it to the security cable slot on your Dell computer. For more information,
see the instructions included with the device.
NOTICE: Before you buy an antitheft device, ensure that it will work with the security cable slot on your computer.
Passwords
Passwords prevent unauthorized access to your computer. When you first start your computer, you must assign a primary password at the prompt. If you do
not enter a password within 2 minutes, the computer returns to its previous operating state.
When using passwords, observe the following guidelines:
l
Choose a password that you can remember, but not one that is easy to guess. For example, do not use the names of family members or pets for
passwords.
l
It is recommended that you do not write down your password. If you do write it down, however, ensure that the password is stored in a secure
location.
l
Do not share your password with other people.
l
Ensure that people are not watching you when you type your password.
NOTICE: Passwords provide a high level of security for data in your computer or hard drive. However, they are not foolproof. If you require more
security, obtain and use additional forms of protection such as data encryption programs.
Use the User Accounts option in the Control Panel in the Microsoft® Windows® operating system to create user accounts or to change passwords. Once you
create a user password, you must enter it each time you turn on or unlock your computer. If you do not enter a password within 2 minutes, the computer
returns to its previous operating state. For more information, see your Windows documentation.
If you forget any of your passwords, contact Dell (see Contacting Dell). For your protection, Dell technical support staff will ask you for proof of your identity to
ensure that only an authorized person can use the computer.
If Your Computer Is Lost or Stolen
l
Call a law enforcement agency to report the lost or stolen computer. Include the Service Tag in your description of the computer. Ask that a case
number be assigned and write down the number, along with the name, address, and phone number of the law enforcement agency. If possible, obtain
the name of the investigating officer.
NOTE: If you know where the computer was lost or stolen, call a law enforcement agency in that area. If you do not know, call a law enforcement
agency where you live.
l
If the computer belongs to a company, notify the security office of the company.
l
Contact Dell customer service to report the missing computer. Provide the computer Service Tag, the case number, and the name, address, and phone
number of the law enforcement agency to which you reported the missing computer. If possible, give the name of the investigating officer.
The Dell customer service representative will log your report under the computer Service Tag and record the computer as missing or stolen. If someone calls
Dell for technical assistance and gives your Service Tag, the computer is identified automatically as missing or stolen. The representative will attempt to get
the phone number and address of the caller. Dell will then contact the law enforcement agency to which you reported the missing computer.

Power Protection Devices
Several devices are available to protect against power fluctuations and failures:
l
Surge protectors
l
Line conditioners
l
Uninterruptible power supplies (UPS)
Surge Protectors
Surge protectors and power strips equipped with surge protection help prevent damage to your computer from voltage spikes that can occur during electrical
storms or after power interruptions. Some surge protector manufacturers include warranty coverage for certain types of damage. Carefully read the device
warranty when choosing a surge protector. A device with a higher joule rating offers more protection. Compare joule ratings to determine the relative
effectiveness of different devices.
NOTICE: Most surge protectors do not protect against power fluctuations or power interruptions caused by nearby lightning strikes. When lightning
occurs in your area, disconnect the telephone line from the telephone wall jack and disconnect your computer from the electrical outlet.
Many surge protectors have a telephone jack for modem protection. See the surge protector documentation for modem connection instructions.
NOTICE: Not all surge protectors offer network adapter protection. Disconnect the network cable from the network wall jack during electrical storms.
Line Conditioners
NOTICE: Line conditioners do not protect against power interruptions.
Line conditioners are designed to maintain AC voltage at a fairly constant level.
Uninterruptible Power Supplies
NOTICE: Loss of power while data is being saved to the hard drive may result in data loss or file damage.
NOTE: To ensure maximum battery operating time, connect only your computer to a UPS. Connect other devices, such as a printer, to a separate power
strip that provides surge protection.
A UPS protects against power fluctuations and interruptions. UPS devices contain a battery that provides temporary power to connected devices when
AC power is interrupted. The battery charges while AC power is available. See the UPS manufacturer documentation for information on battery operating time and to ensure that the device is approved by Underwriters Laboratories (UL).

Your wireless network card requires specific software and drivers for connecting to a network. The software is already installed.
NOTE: If the software is removed or corrupted, follow the instructions in the user documentation for your wireless network card. Verify the type of
wireless network card installed in your computer and then search for that name on the Dell™ Support website at support.dell.com. For information on
the type of wireless network card that is installed in your computer, see Checking Your Wireless Network Card.
When you turn on your computer and a network (for which your computer is not configured) is detected in the area, a pop-up appears near the network icon
in the Windows notification area.
To connect to the network:
1.
Click Start
2.
Click Network and Sharing on the navigation bar at the top of the Network folder.
, and then click Network.
3.
Click Connect to a network under Tasks.
4.
Select your network from the list and click Connect.
Once you have configured your computer for a wireless network, another pop-up notifies you that your computer is connected to that network.
Thereafter, whenever you log on to your computer within the range of the wireless network that you selected, the same pop-up notifies you of the wireless
network connection.
NOTE: If you select a secure network, you must enter a WEP or WPA key when prompted. Network security settings are unique to your network. Dell
cannot provide this information.
NOTE: Your computer can take up to 1 minute to connect to the network.

Mobile Broadband (or Wireless Wide Area Network)
A Mobile Broadband network, also known as a Wireless Wide Area Network (WWAN), is a high-speed digital cellular network that provides Internet access
over a much wider geographical area than a WLAN, which typically covers only from 100 to 1000 feet. Your computer can maintain Mobile Broadband network
access as long as the computer is within a cellular-data coverage zone. Contact your service provider for coverage of a high-speed digital cellular network.
NOTE: Even if you are able to make a call from your cellular phone in a specific geographical location, that location may not necessarily be within a
cellular-data coverage zone.
What You Need to Establish a Mobile Broadband Network Connection
NOTE: Depending on your computer, you can use either a Mobile Broadband ExpressCard or Mini Card, but not both, to establish a Mobile Broadband
network connection.
To set up a Mobile Broadband network connection, you need:
l
A Mobile Broadband ExpressCard or Mini Card (depending on your computer's configuration)
NOTE: For instructions on using ExpressCards, see Using ExpressCards.
l
An activated Mobile Broadband ExpressCard or activated Subscriber Identity Module (SIM) for your service provider
l
The Dell Mobile Broadband Card Utility (already installed on your computer if you purchased the card when you purchased your computer, or on the

connection (see What You Need to Establish a Mobile Broadband Network Connection), and then verify that your Mobile Broadband card is enabled by
verifying the setting of the wireless switch.
You can turn your Mobile Broadband card on and off using the wireless switch on your computer.
You can turn your computer's wireless devices on and off with the wireless switch on the left side of the computer (see Left Side View).
If the switch is in the on position, move the switch to the off position to disable the switch and the Mobile Broadband card. If the switch is in the off position,

Dell Wi-Fi Catcher™ Network Locator The wireless switch on your Dell computer uses the Dell Wi-Fi Catcher Network Locator to scan specifically for wireless networks in your vicinity.
To scan for a wireless network, slide and hold the wireless switch (see wireless switch) in the momentary position for a few seconds. The Wi-Fi Catcher
Network Locator functions regardless of whether your computer is turned on or off, or in Sleep state, as long as the switch is configured through Dell QuickSet
or the BIOS (system setup program) to control Wi-Fi network connections.
NOTE: The Wi-Fi Catcher Network Locator light appears only when the computer is turned off and the wireless switch is configured in the system setup
program (BIOS) to control Wi-Fi network connections.
Because the Wi-Fi Catcher Network Locator is disabled and not configured for use when your computer is shipped to you, you must first use Dell QuickSet to
enable and configure the switch to control Wi-Fi network connections. For more information on the Wi-Fi Catcher Network Locator and to enable the feature
through Dell QuickSet, right-click the QuickSet icon in the notification area, and then select Help.
