The Basics

This chapter introduces important basics about your PowerBook that youll want to know. Getting to Know Your New PowerBook
Because your PowerBook is so thin and light, you can take it with you to the office, library, class, or wherever you work or play. Whenever you stop using your PowerBook, wait a few moments to let the hard disk and any optical disc in your drive stop spinning before you transport the computer. Avoid jostling or bumping your PowerBook while discs are spinning. When using your PowerBook or when charging the battery, it is normal for the bottom of the case to get warm. For prolonged use, place your PowerBook on a flat, stable surface. The bottom of the case is raised slightly to allow airflow that keeps the unit within normal operating temperatures. As you get to know your new computer, you may hear small noises during startup and when using your hard disk and optical drives. For example, your hard disk and optical drives may whir and click as they access information or load and eject discs. After the PowerBook runs for some time, a small fan may turn on to cool it, producing a faint sound. Small noises are part of the PowerBooks normal functioning. For more safety instructions about handling and using your PowerBook in different locations, be sure to see Appendix B, Safety, Use, and Care Information, on page 67.

FireWire

Your computer has one FireWire 400 and one FireWire 800 port ( ). With FireWire, you can easily connect and disconnect external high-speed devicessuch as DV cameras, printers, scanners, and hard diskswithout restarting your computer. You can connect a standard 6-pin FireWire device directly to the FireWire 400 port. You can use a 9-to-6-pin FireWire cable to connect the device to the FireWire 800 port. You can also connect 9-pin FireWire devices directly to the FireWire 800 port, for even faster connections. Both ports provide power to connected devices (so the devices dont need an additional power plug).
FireWire 400 port (6-pin)
FireWire 800 port (9-pin)
These are some of the things you can do with FireWire: Connect a digital videocamera and capture, transfer, and edit high-quality video directly on your computer using video-editing software such as iMovie or Final Cut Pro. Connect an external FireWire hard disk and use it to back up data or transfer files. Start up from an external FireWire hard disk. Connect an external FireWire hard disk (with a valid operating system installed on it), open the Startup Disk pane of System Preferences, and click the FireWire hard disk. Restart your computer.

Using FireWire Devices

To use a FireWire device with your computer, connect the device to the computer and install any software that came with the device. Your computer automatically detects newly connected devices.
LL2507.book Page 35 Thursday, March 11, 2004 5:16 PM
FireWire Devices and Battery Power
FireWire devices, such as certain external hard disks, can get power from the PowerBook FireWire connection instead of a separate power adapter. However, these types of FireWire devices will cause your PowerBook battery to become depleted faster. If a device will be connected for an extended period, it is a good idea to connect the PowerBook power adapter. Note: The FireWire ports are designed to support power for FireWire devices (up to 7 watts maximum). You can connect multiple devices to each other and connect the daisy-chain of devices to the FireWire port on your computer, but only one device should get power from the computer. The rest of the devices in the daisy-chain should be powered by separate power adapters. Connecting more than one FireWire device that gets power from the port may cause problems. If a problem occurs, shut down the computer, remove the FireWire devices, and restart your computer.

For More Information on Using Ethernet
Additional information, including setting up an Ethernet network and transferring files using Ethernet, is available in Mac OS Help. Choose Help > Mac Help from the menu bar and search for Ethernet or network. For information on networking products you can use with your PowerBook, check the Macintosh Products Guide at www.apple.com/guide.

Using Your Modem

Your computer comes with an Apple 56K v.92 modem installed. To connect the modem, plug one end of the phone cord or RJ-11 cable into the modem port on the computer and the other end into a standard RJ-11 telephone wall jack. Make sure you connect to an analog phone linethe kind used typically in homes. The modem will not work with a digital phone line. Warning: Do not connect a digital telephone line to the modem as it could damage the modem. Contact your telephone service provider if you are unsure whether you have a digital telephone line. For information on how to establish an Internet connection, see Appendix C, Connecting to the Internet, on page 73. More information about the internal modem is also available in Mac OS Help.

Top Ten Questions

Do you have a question? Here are the top ten questions commonly asked by new PowerBook users.
My Internet connection doesnt seem to be working. How do I set it up? There are different types of Internet connections. For example, you can connect via a modem, a DSL connection, a wireless AirPort connection, or an Ethernet network. You will need to supply Mac OS X with specific information about your connection type, Internet service provider, or network. The first step in configuring your connection is gathering the information needed for your connection type. To find out what information you need and for instructions on how to configure your connection type, see Appendix C, Connecting to the Internet, on page 73. Your computer also has a Setup Assistant application to help walk you through setting up an Internet connection. Open System Preferences and click Network. Click the Assist me button to open Network Setup Assistant. How do I set up my printer? Is it compatible with my PowerBook? Begin by connecting your printer and installing any software according to the instructions that came with your printer. Next, open System Preferences and click the Print & Fax icon. Use the Print & Fax pane to configure your PowerBook to access the printer. Youll find lots of information about setting up printers in Mac OS Help (search for printer). Also see Connecting to a Printer on page 25 of this manual. If your printer doesnt seem to be working as expected, you may need to check the manufacturers website for updated print drivers. Often the latest printer software is available for downloading. If you sent a print job to your printer, but its not printing, check to see if the print job is stopped or on hold by clicking the printer icon in the Dock. (If no icon appears in the Dock, open Printer Setup Utility in the Applications/Utilities folder and double-click the printers name.) If the window for the printer says Job Stopped, click the Start Jobs button. If Hold appears beside the job name, resume printing by clicking the job name and clicking Resume. If a print job has stopped printing because of a technical error, you can delete the faulty job by selecting the job and clicking Delete. You can then try printing the job again.

Getting to Know Your PowerBook
This chapter introduces important basics about your PowerBook.
Because your PowerBook is so thin and light, you can take it with you to the office, library, class, or wherever you work or play. Whenever you stop using your PowerBook, wait a few moments to let the hard disk and any optical disc (such as a CD or DVD) in your drive stop spinning before you transport the computer. Avoid jostling or bumping your PowerBook while discs are spinning. Note: Your PowerBook uses Sudden Motion Sensor technology to help protect the hard disk if the computer is dropped or experiences extreme vibration. See Understanding Sudden Motion Sensor on page 51 for more information. When you use your PowerBook or charge its battery, it is normal for the bottom of the case to get warm. For prolonged use, place your PowerBook on a flat, stable surface. The bottom of the case is raised slightly to allow airflow that keeps the unit within normal operating temperatures. As you get to know your new PowerBook, you might hear system sounds during startup and when using your hard disk and optical drive. After the PowerBook runs for some time, small fans might turn on to cool it, producing a faint sound. System sounds such as these are part of the computers normal functioning. For more safety instructions about handling and using your PowerBook in different locations, make sure to see Appendix B, Safety, Use, and Care Information, on page 73.

Keeping Your Software Up to Date
You can connect to the Internet and automatically download and install the latest free software versions, drivers, and other enhancements from Apple. When you are connected to the Internet, Software Update checks Apples Internet servers to see if any updates are available for your computer. You can set your Mac to check the Apple server periodically and download and install updated software. To check for updated software: 1 Open System Preferences. 2 Click the Software Update icon and follow the directions on the screen.
For more information, search for Software Update in Mac Help. For the latest information about Mac OS X, go to the Mac OS X website at www.apple.com/macosx.

Connecting to a Printer

Follow the instructions that came with your printer to install the required software and connect the printer. The drivers for most printers are built in to Mac OS X. You can connect many printers with a USB cable; others require a network connection, such as Ethernet. If you have an AirPort Express or AirPort Extreme Base Station, you can connect a USB printer to the base station (instead of connecting it to your computer) and print wirelessly. For more information about your USB ports, see Using Universal Serial Bus (USB) Devices on page 34. For more information about a wireless or network connection, see Understanding AirPort Extreme Wireless Networking on page 39 and Connecting With Ethernet (10/100/1000Base-T) on page 43.
After you connect a USB or FireWire printer, your computer usually detects it automatically and adds it to the list of available printers. You might need to know the network name or address of printers connected to a network before you can print to them. Use the Print & Fax pane of System Preferences to select your printer. To set up a printer: 1 Open System Preferences and click the Print & Fax icon. 2 Click Printing and then click the Add button (+) to add a printer. 3 Select the printer you want to use, and then click Add. 4 Use the Add button (+) and Remove button () to choose the printers that appear in the printer list.

Monitoring Printing

After you send a document to a printer, you can monitor printing, including deleting your print job or putting it temporarily on hold. Click the printer icon in the Dock to open the Printer window. For more information, choose Help > Mac Help and search for printing.

Using FireWire Devices

To use a FireWire device with your computer, connect the device to the computer and install any software that came with the device. Your computer automatically detects newly connected devices. Note: If your PowerBook cannot find the correct software when you connect a FireWire device, you can either install the software that came with the device or follow the onscreen prompts to use the Internet to locate, download, and install the correct software.
Understanding FireWire Devices and Battery Power
You can use FireWire devices, such as certain external hard disks, which are powered by the PowerBook FireWire connection instead of a separate power adapter. However, these types of FireWire devices can cause your PowerBook battery to become depleted faster. If you are using the device for an extended period, it is a good idea to connect the PowerBook power adapter. Note: The FireWire ports are designed to support power for FireWire devices (up to 7 watts maximum). You can connect multiple devices to each other and connect the daisy chain of devices to the FireWire port on your computer, but only one device should get power from the computer. The rest of the devices in the daisy chain should be powered by separate power adapters. Connecting more than one FireWire device that gets power from the port can cause problems. If a problem occurs, shut down the computer, disconnect the FireWire devices, and restart your computer.
Connecting Your PowerBook to Another Computer Using FireWire
If you want to transfer files between your PowerBook and another FireWire-equipped Macintosh computer, or you have a problem that prevents your computer from starting up, you can use FireWire Target Disk Mode to connect to another computer. When you start up your computer in FireWire Target Disk Mode, the other computer can access your PowerBook as if it were an external hard disk. Note: When using FireWire Target Disk Mode, its a good idea to connect your power adapter to the PowerBook. To connect your PowerBook to another computer in FireWire Target Disk Mode: 1 Make sure that your PowerBook is shut down. 2 Use a FireWire cable to connect your PowerBook to another FireWire-equipped computer. 3 Start up your PowerBook and immediately hold down the T key. Your PowerBook display shows the FireWire logo. The other computers display shows the PowerBook internal hard disk icon. You can now drag and drop files between the computers.

Using External Video Support (DVI, VGA, and S-Video)
Your computer has an external monitor (DVI) port that allows you to directly connect a display or projector with a DVI port. Use the included DVI-to-VGA adapter to connect your PowerBook to monitors and projectors that have VGA connectors. The TV out port (also known as an S-video out port) on your computer lets you connect to a television, videocassette recorder (VCR), or video projection system using an S-video cable. You can use TV out to display images on a television, record computer images on a VCR, or play DVD-Video discs on your TV.
If the device you want to connect has a composite port rather than an S-video port, you can use the S-video-to-composite adapter that came with your PowerBook.

DVI port

S-video out port
When an external monitor or TV is connected, you can either have the same image appear on both the internal display and the external monitor (known as video mirroring) or use the external monitor to extend the size of the Mac OS desktop (known as dual-display mode). By default, your PowerBook starts up in dual-display mode. Press the F7 (i) key to switch between dual-display and video-mirroring modes. If you want sound to come from the external display, such as a projector or TV, you need to connect an audio cable from the computers headphone port (f ) to that device. Note: Because of the display limitations of most TVs, images displayed on the TV screen will be of lower quality than those on the built-in display or an external monitor.
Connecting an External Display or Projector
To connect an external display or projector with a DVI connection to your computer: 1 Turn on the external display or projector. 2 Make sure the display cable is connected to the external projector or display. 3 Connect the display cable to your PowerBook. Your PowerBook automatically detects the external display. 4 Adjust the resolution on the external display by using the Displays pane of System Preferences or the Displays icon in the menu bar.
To connect an external display or projector with a VGA connection to your computer: 1 Turn on the external display or projector. 2 Make sure the display cable is connected to the external projector or display. 3 Connect the DVI-to-VGA adapter that came with your PowerBook to the VGA connector of the external display or projector, and then connect the adapter to your PowerBook.

Read this important PowerBook safety and maintenance information. Safety Instructions for Setting Up and Using Your Computer
Be aware of the following safety tips and warnings as you work with your PowerBook.
Plugging In the Power Adapter
Always leave space around your power adapter. Do not use this equipment in a location where airflow around the power adapter or computer is confined. For best results, always connect your AC cord and use a grounded outlet when one is available. Always disconnect the power adapter and remove the battery before opening the computer to perform procedures such as installing memory. Warning: Use only the power adapter that came with your PowerBook computer. Adapters for other electronic devices (including other PowerBook models and other portable computers) might look similar, but they can negatively affect your computers performance or damage your computer.
Connecting a Phone Line to the Internal Modem
Always disconnect the phone cord before opening the computer to perform procedures such as installing memory or removing the hard disk. Warning: Do not connect a digital phone line to the modem; the wrong type of line could damage the modem. Contact your telephone service provider if you are unsure whether you have a digital phone line.
Using Connectors and Ports
Never force a connector into a port. If the connector and port dont join with reasonable ease, they probably dont match. Make sure that the connector matches the port and that you have positioned the connector correctly in relation to the port.
When youre using your PowerBook or charging the battery, it is normal for the bottom of the case to get warm. For prolonged use, place your PowerBook on a flat, stable surface. The bottom of the PowerBook case functions as a cooling surface that transfers heat from inside the computer to the cooler air outside. The bottom of the case is raised slightly to allow airflow that keeps the unit within normal operating temperatures. In addition, the computer vents warm air from the back of the case. Warning: Do not place your PowerBook on a pillow or other soft material when it is on, as the material can block the airflow vents, in particular the rear vents, and cause the computer to overheat. Never place anything over your keyboard before closing the display. This can cause your computer to cycle on and off which might create excessive heat and drain your battery. Never turn on your computer unless all of its internal and external parts are in place. Operating the computer when it is open or missing parts can be dangerous and can damage your computer.

Make sure that you always do the following: Keep your computer away from sources of liquids, such as drinks, washbasins, bathtubs, shower stalls, and so on. Protect your computer from dampness or wet weather, such as rain, snow, and so on. Read all the installation instructions carefully before you plug your computer in to a wall socket. Keep these instructions handy for reference by you and others. Follow all instructions and warnings dealing with your computer. Important: Electrical equipment can be hazardous if misused. Operation of this product, or similar products, must always be supervised by an adult. Do not allow children access to the interior of any electrical product and do not permit them to handle any cables. Warning: Never push objects of any kind into this product through the openings in the case. Doing so can be dangerous and might result in fire or electric shock.

Handling the Battery

Warning: There is risk of explosion if the battery is replaced by an incorrect type. Dispose of used batteries according to your local environmental guidelines. Dont puncture or incinerate the battery.

Avoiding Hearing Damage

Warning: Permanent hearing loss may occur if earbuds or headphones are used at high volume. You can adapt over time to a higher volume of sound that may sound normal but can be damaging to your hearing. If you experience ringing in your ears or muffled speech, stop listening and have your hearing checked. The louder the volume, the less time is required before your hearing could be affected. Hearing experts suggest that to protect your hearing: Limit the amount of time you use earbuds or headphones at high volume. Avoid turning up the volume to block out noisy surroundings.

Understanding Ergonomics

Here are some tips for setting up a healthy work environment.

Keyboard and Trackpad

When you use the keyboard and trackpad, your shoulders should be relaxed. Your upper arm and forearm should form an angle that is slightly greater than a right angle, with your wrist and hand in roughly a straight line.

Not this

Use a light touch when typing or using the trackpad and keep your hands and fingers relaxed. Avoid rolling your thumbs under your palms.
Change hand positions often to avoid fatigue. Some computer users might develop discomfort in their hands, wrists, or arms after intensive work without breaks. If you begin to develop chronic pain or discomfort in your hands, wrists, or arms, consult a qualified health specialist.
An adjustable chair that provides firm, comfortable support is best. Adjust the height of the chair so your thighs are horizontal and your feet flat on the floor. The back of the chair should support your lower back (lumbar region). Follow the manufacturers instructions for adjusting the backrest to fit your body properly.
