Microsoft®Windows®Power Meter
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.
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, click the Start
button®Settings®Control Panel®Power Options®Power Meter tab.
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 a CD or DVD.
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 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

Charge Gauge
By either pressing once or pressing and holding the status button on the charge gauge on the battery, 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. That is, 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-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.

Check the Battery Health
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.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Battery for more information about the
battery operating time.

Low-Battery Warning
The battery status light on the hinge cover (at the lower-right corner of the display) flashes orange when the battery charge is low, and it is solid orange
when the battery charge is critically low. Also, a pop-up window warns you when the battery charge is approximately 90 percent depleted. 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.
You can change the settings for the battery alarms in QuickSet or the Power Options Properties window. See Configuring Power Management Settings for
information about accessing QuickSet or the Power Options Properties window.
Conserving Battery Power
Perform the following actions to conserve battery power:
lConnect the computer to an electrical outlet when possible because battery life is largely determined by the number of times the battery is used and
recharged.
1

Card Types
Installing a PC Card or ExpressCard
Removing a Card or Blank
Card Types

PC Cards
See Specifications for information on supported PC Cards.
The PC Card slot has one connector that supports a single Type I or Type II card. The PC Card slot supports CardBus technology and extended PC Cards.
"Type" of card refers to its thickness, not its functionality.

ExpressCards
See Specifications for information on supported ExpressCards.
ExpressCards leverage PC Card technology to provide a fast and convenient way to add memory, wired and wireless network communications (including
Mobile Broadband network [also known as WWAN] communications), multimedia, and security features to your computer. To use an ExpressCard in the PC
Card slot, you must use an adapter. The adapter is included with the ExpressCard.

Smart Cards
Smart cards provide valuable tools for security, data storage, and special programs (see Using Smart Cards).

Card Blanks
Your computer shipped with a plastic blank installed in the card slots. Blanks protect unused slots from dust and other particles. Save the blank for use when
no card is installed in the slots; blanks from other computers may not fit your computer.
To remove a blank, see Removing a Card or Blank.

Extended Cards
An extended PC Card (for example, a wireless network adapter) is longer than a standard PC Card and extends outside the computer. Follow these
precautions when using extended PC Cards:
lProtect the exposed end of an installed card. Striking the end of the card can damage the system board.
lAlways remove an extended PC Card before you pack the computer in its carrying case.
Installing a PC Card or ExpressCard
You can install a PC Card or ExpressCard in the computer while the computer is running. The computer automatically detects the card.
PC Cards and ExpressCards are generally marked with a symbol (such as a triangle or an arrow) to indicate which end to insert into the slot. The cards are
keyed to prevent incorrect insertion. If card orientation is not clear, see the documentation that came with the card.

NOTE: Electrical and electronic devices are sensitive to electrostatic discharge (ESD). If a substantial ESD occurs, the device may reset and the device
software may attempt to reinitialize a connection. If the software is not operational after an ESD occurrence, restart the modem software program.
NOTE: A PC Card is not a bootable device.
NOTE: An ExpressCard is not a bootable device.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

PC Card

1. Hold the card with its orientation symbol pointing into the slot and the top side of the card facing up. The latch may need to be in the "in" position
before you insert the card.

2. Slide the card into the slot until the card is completely seated in its connector.
If you encounter too much resistance, do not force the card. Check the card orientation and try again.
The computer recognizes most PC Cards and automatically loads the appropriate device driver. If the configuration program tells you to load the
manufacturer's drivers, use the floppy disk or CD that came with the PC Card.

ExpressCard

1. Place the ExpressCard in the adapter (the adapter is included with the ExpressCard).

2. Install the ExpressCard with adapter the same way as a PC Card (see PC Cards).
Removing a Card or Blank
Press the latch and remove the card or blank. For some latches, you must press the latch twice: once to pop the latch out, and then a second time to pop the
card out.


CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
NOTICE: Click the icon in the taskbar to select a card and stop it from functioning before you remove it from the computer. If you do not stop the
card in the configuration utility, you could lose data. Do not attempt to eject a card by pulling its cable, if one is attached.

and the up-or down-arrow key on the keyboard.
You can press the following keys to adjust display brightness:
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).
Switching the Video Image
When you start the computer with an external device (such as an external monitor or projector) attached and turned on, the image may appear on either the
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
To display a program at a specific resolution, both the graphics card and the display must support the program, and the necessary video drivers must be
installed.
If you choose a resolution or color palette that is higher than the display supports, the settings adjust automatically to the closest supported values.

1. Click the Start button and click Settings®Control Panel.

2. Under Pick a category, click Appearance and Themes.

3. Under Pick a task..., click the area you want to change, or under or pick a Control Panel icon, click Display.

4. In the Display Properties window, click the Settings tab.

5. Try different settings for Color quality and Screen resolution.
If the video resolution setting is higher than that supported by the display, the computer enters pan mode. In pan mode, the entire screen cannot be
displayed at one time. For example, the taskbar that usually appears at the bottom of the desktop may no longer be visible. To view the rest of the screen,
use the touch pad or track stick to pan up, down, left, and right.
Dual Independent Display Mode
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.
NOTE: Before you change any of the default display settings, make a note of the default settings for future reference.
NOTE: Use only the Dell-installed video drivers, which are designed to offer the best performance with your Dell-installed operating system.
NOTE: As the resolution increases, icons and text appear smaller on the screen.
NOTICE: You can damage an external monitor by using an unsupported refresh rate. Before adjusting the refresh rate on an external monitor, see the
user's guide for the monitor.

You can attach an external monitor or projector to your computer and use it as an extension of your display (known as "dual independent display" or
"extended desktop" mode). This mode allows you to use both screens independently and drag objects from one screen to the other, effectively doubling the
amount of viewable work space.

