NOTE: The types of CD or DVD drives offered by Dell may vary by country. The following instructions show how to make an exact copy of a CD or DVD. You can also use Sonic RecordNow for other purposes, including creating CDs from audio files on your computer and creating MP3 CDs. For instructions, see the Sonic RecordNow documentation that came with your computer. Open Sonic RecordNow, click the question mark icon in the upper-right corner of the window, and then click the help or tutorial option. How to Copy a CD or DVD NOTE: If you have a DVD/CD-RW combo drive and you experience recording problems, check for available software patches at the Sonic website at www.sonic.com. Setting Up and Using Your Computer 21 www.dell.com | support.dell.com Currently, five DVD-writable disc formats are available: DVD+R, DVD+RW, DVD-R, DVD-RW, and DVD-RAM. The DVD-writable drives installed in DellTM computers can write to DVD+R and DVD+RW media, and can read DVD-R and DVD-RW media. However, DVD-writable drives do not write to and might not read DVD-RAM media. In addition, commercially available DVD players for home theater systems might not read all five formats. NOTE: Most commercial DVDs have copyright protection and cannot be copied using Sonic RecordNow. 1 Click the Start button, point to All Programs Sonic RecordNow!, and then click RecordNow! 2 Click either the audio tab or the data tab, depending on the kind of CD or DVD you want to copy. 3 Click Exact Copy. 4 To copy the CD or DVD: · If you have one optical drive, ensure that the settings are correct and click Copy. The computer reads your source CD or DVD disc and copies it to a temporary folder on your computer hard drive. When prompted, insert a blank CD or DVD disc into the optical drive and click OK. · If you have two optical drives, select the drive into which you have inserted your source CD or DVD disc and click Copy. The computer copies the data on the CD or DVD to the blank CD or DVD. After you finish copying the source CD or DVD, the CD or DVD that you created automatically ejects. Using Blank CD-Rs, CD-RWs, DVD+R, and DVD+RW Use blank CD-Rs to record music or permanently store data files. After creating a CD-R disc, you cannot write to that CD-R again (see the Sonic documentation for more information). Use blank CD-RWs to write to CD or to erase, rewrite, or update data on CDs. Your DVD-writable drive can write to four different types of recording media--CD-Rs, CD-RWs (including high-speed CD-RWs), DVD+Rs, and DVD+RWs. Blank DVD+Rs can be used to permanently store large amounts of information. After you create a DVD+R, you may not be able to write to that disc again if the disc is "finalized" or "closed" during the final stage of the disc creation process. Use blank DVD+RWs if you plan to erase, rewrite, or update information on that disc later. Helpful Tips · · Use Microsoft® Windows® Explorer to drag and drop files to a CD-R or CD-RW disc only after you start Sonic RecordNow and open a RecordNow project. You must use CD-R discs to burn music CDs that you want to play in regular stereos. CD-RWs do not play in most home or car stereos. 22 Setting Up and Using Your Computer · · · You cannot create audio DVDs with Sonic RecordNow. Music MP3 files can be played only on MP3 players or on computers that have MP3 software installed. 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 650-MB blank CD. The optical drive needs 1 or 2 MB of the blank CD to finalize the recording. 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-RWs 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. See the Sonic support website at support.sonic.com for additional information. · · Power Management The Microsoft® Windows® XP power management features can reduce the amount of electricity your computer uses when it is on and you are not using it. You can reduce power to just the monitor or the hard drive, or you can use standby mode or hibernate mode to reduce power to the entire computer. When the computer exits from a power conservation mode, the Windows desktop is restored to the state it was in before it entered the mode. NOTE: Windows XP Professional includes security and networking features not available in Windows XP Home Edition. When a Windows XP Professional computer is connected to a network, different options related to security and networking appear in certain windows. Standby Mode Standby mode conserves power by turning off the display and the hard drive after a time-out. When the computer exits from standby mode, it returns to the operating state it was in before it entered standby mode. To set standby mode to automatically activate after a defined period of inactivity: 1 Click the Start button and click Control Panel. 2 Under Pick a category, click Performance and Maintenance. 3 Under or pick a Control Panel icon, click Power Options. To immediately activate standby mode without a period of inactivity, click the Start button, click Turn Off Computer, and then click Stand by. To exit from standby mode, press a key on the keyboard or move the mouse. NOTICE: If your computer loses power while in standby mode, it may lose data. Setting Up and Using Your Computer 23 www.dell.com | support.dell.com Hibernate Mode Hibernate mode conserves power by copying system data to a reserved area on the hard drive and then completely turning off the computer. When the computer exits from hibernate mode, the desktop is restored to the state it was in before it entered hibernate mode. To activate hibernate mode: 1 Click the Start button and click Control Panel. 2 Under Pick a category, click Performance and Maintenance. 3 Under or pick a Control Panel icon, click Power Options. 4 Define your hibernate settings on the Power Schemes tab, Advanced tab, and Hibernate tab. To exit from hibernate mode, press the power button. The computer may take a short time to exit from hibernate mode. Pressing a key on the keyboard or moving the mouse does not bring the computer out of hibernation, because the keyboard and the mouse do not function when the computer is in hibernate mode. Because hibernate mode requires a special file on your hard drive with enough disk space to store the contents of the computer memory, Dell creates an appropriately sized hibernate mode file before shipping the computer to you. If the computer's hard drive becomes corrupted, Windows XP recreates the hibernate file automatically. Power Options Properties Define your standby mode settings, hibernate mode settings, and other power settings in the Power Options Properties window. To access the Power Options Properties window: 1 Click the Start button and click Control Panel. 2 Under Pick a category, click Performance and Maintenance. 3 Under or pick a Control Panel icon, click Power Options. 4 Define your power settings on the Power Schemes tab, Advanced tab, and Hibernate tab. Power Schemes Tab Each standard power setting is called a scheme. If you want to select one of the standard Windows schemes installed on your computer, choose a scheme from the Power schemes drop-down menu. The settings for each scheme appear in the fields below the scheme name. Each scheme has different settings for starting standby mode or hibernate mode, turning off the monitor, and turning off the hard drive. The Power schemes drop-down menu displays the following schemes: · · · 24 Always On (default) -- If you want to use your computer with no power conservation. Home/Office Desk -- If you use your computer as a home or office computer and you require minimal power conservation. Portable/Laptop -- If your computer is a portable computer that you use for traveling. Setting Up and Using Your Computer · · · Presentation -- If you want your computer to run without interruption (using no power conservation). Minimal Power Management -- If you want your computer to run with minimal power conservation. Max Battery -- If your computer is a portable computer and you run your computer from batteries for extended periods of time. If you want to change the default settings for a scheme, click the drop-down menu in the Turn off monitor, Turn off hard disks, System stand by, or System hibernates field, and then select a timeout from the displayed list. Changing the time-out for a scheme field permanently changes the default settings for that scheme, unless you click Save As and enter a new name for the changed scheme. NOTICE: If you set the hard drive (hard disk) to time-out before the monitor does, your computer may appear to be locked up. To recover, press any key on the keyboard or click the mouse. To avoid this problem, always set the monitor to time-out before the hard drive. Advanced Tab The Advanced tab allows you to: · · · Place the power options icon in the Windows taskbar for quick access. Set the computer to prompt you for your Windows password before the computer exits from standby mode or hibernate mode. Program the power button to activate standby mode, activate hibernate mode, or turn off the computer. To program these functions, click an option from the corresponding drop-down menu and click OK. Hibernate Tab The Hibernate tab allows you to enable hibernate mode. If you want to use the hibernate settings you defined on the Power Schemes tab, click the Enable hibernate support check box on the Hibernate tab.
