(Sample Illustration) Optional external USB diskette drive

Turning off the computer

To connect an optional external USB diskette drive, connect the cable to one of the computers USB ports.
(Sample Illustration) Connecting an optional external USB diskette drive
Pressing the power button before shutting down the Windows operating system could cause you to lose your work. Make sure the system indicator panels disk light and the drive-in-use light are off. If you turn off the power while a disk/disc is being accessed, you may lose data or damage the disk/disc and/or drive. It is a good idea to turn off your computer when you are not using it for a while. If you are using the computer for the first time, leave the computer plugged into a power source (even though the computer is off) to fully charge the main battery.
Options for turning off the computer
Depending on the operating system installed, you have more than one option available for turning off the computer: Turn Off or Shut Down, Hibernate, and Standby. Each option has its advantages.

Turn Off or Shut Down

Factors to consider when choosing either Turn Off or Shut Down: Use the Turn Off command if you are not connected to a domain server. Use the Shut Down command if you are connected to a domain server. If you have work in progress and are not connected to a network, use the Windows Standby or Hibernate commands to save your system settings so that, when you turn on the computer again, you will automatically return to where you left off.

Ensure the operating system is set up for your printer as described in Setting up a printer on page 69. HINT: You only need to set up the printer the first time you connect it. If you use more than one printer or are changing printers, you will need to set up the Windows operating system to run with the additional printer(s). To print a file: 1 If your printer is not on, turn it on now.

Backing up your work

In your Windows application, click File, and then Print. The program displays a Print dialog box.
(Sample Image) Print dialog box Specify the print parameters. For example, the range of pages and number of copies to print. Click Print.
Back up all the files you create in case something happens to your computer. You can back up your files to different types of media such as CDs, DVDs, diskettes, or to a network, if available. To back up several files at one time, use the Microsoft Windows backup program preinstalled on the computers hard disk. Also see Backing up your data to CDs with the Windows operating system on page 204. HINT: Backing up all the files on your hard disk may take a considerable amount of time and multiple CDs/DVDs. You may prefer to use a high-capacity backup system, such as an external hard drive. Small files can be backed up on diskettes if an optional external diskette drive is available.

Using the optical drive

Restoring your work
To restore information from your backup media to your hard disk, use the Restore page in the backup program. Look in the online Help or your operating system documentation for information on restoring files. TECHNICAL NOTE: When restoring files, the backup program prompts you if you try to overwrite a file that already exists on the hard disk. Make sure the backup version is the one you want before overwriting the existing file.
Optical storage has become the preferred medium for software, music, and video. Digital versatile discs (DVDs) provide a significant increase in data storage and support features that are not available on any other video platform. These features include widescreen movies, multiple language tracks, digital surround sound, multiple camera angles, and interactive menus. For these reasons, your computer may come with an optical drive. TECHNICAL NOTE: Your optical drive is set to play region 1 (North America) DVD-ROMs. If you play a DVD disc from another region, the drive will automatically change to play in the format of the other region. The drive will allow you to change regions four times. On the fourth change, the region will be locked in. That is, the drive will only play DVDs from that last region. Note that changing from region 1 to region 2 and back to region 1 is counted as two changes.

Conserving battery power

How long a fully charged battery pack lasts when you are using the computer depends on a number of factors, such as: How the computer is configured How much you use the hard disk, optical drive, diskette drives, or other optional devices Where you are working, since operating time decreases at low temperatures
There are various ways in which you can conserve power and extend the operating time of your battery: Enable Standby or Hibernation, which saves power when you turn off the computer and turn it back on again Use Toshibas power-saving options
These power-saving options control the way in which the computer is configured. By using them, you can increase the length of time you can use the computer before you need to recharge the battery.
Toshiba has combined these options into preset Power Profiles. Using one of these profiles lets you choose between maximum power savings and peak system performance. You may also set individual power-saving options to suit your own needs. The following sections describe how to choose a Power Profile and discuss each power-saving option.

Power Profiles

You can choose a predefined Power Profile or select your own combination of power management options. To do this: 1 Click Start, Control Panel, Performance and Maintenance, and then TOSHIBA Power Saver.
The TOSHIBA Power Saver Properties window appears.
(Sample Image) TOSHIBA Power Saver Properties window 2 Select an appropriate profile for your work environment or create your own custom profile.
By changing the options that appear in the Power Saver Properties dialog box and clicking OK, you can reconfigure that function. You may choose a power-saving management strategy to best suit your computing needs. If you are running on batteries and the programs that you are using do not require a lot of system resources, you may experience longer work sessions by enabling the Normal setting. Any options that you change become the active settings when you exit the program. (You do not have to restart your system before they become active settings.) For more information, see TOSHIBA Power Saver on page 151.
Changing the main battery
Using a hot key to set the Power Profile
You may use a hot key to set the Power Profile. To set the Power Profile: 1 Press Fn and F2 simultaneously to display the Power Profile pop-up window.
(Sample Image) Power Profile pop-up window 2 While continuing to press Fn, press F2 until you select the desired Power Profile. The Power Profile options are: Full Power, AC Optimized, High Power, Normal, DVD Playback, Presentation, and Long Life. 3 Release the Fn key. The pop-up window disappears. You are now in the selected mode. For more information on setting the battery Power Profile, see TOSHIBA Power Saver on page 151.

Removing memory media

1 Prepare the media for removal by clicking the Safely Remove Hardware icon in the System tray and then selecting the card or device you want to remove. If the system is unable to prepare the media for safe removal, a message will tell you to try again later. If the media can be removed now, the system displays Safe to Remove Hardware. Gently press the card inward to release it. The card pops out slightly. Grasp the card and pull it straight out.
(Sample Illustration) Removing memory media Do not remove memory media while data is being written or read. Even when the Windows message copying. disappears, writing to the media might still be in progress and your data could be destroyed. Wait for the indicator light to go out.

Using the i.LINK port

(Available on certain models) The i.LINK port on the front of the computer provides an extremely fast data transfer rate. In addition to high speed, the i.LINK port also supports isochronous data transfer (the delivery of data at a guaranteed rate). This makes it ideal for devices that transfer high levels of data in real-time, such as video devices. As with USB ports, the i.LINK port supports both Plug-and-Play (automatic configuration) and hot swapping (the ability to connect and disconnect devices while the computer is on).
Using an expansion device
The expansion port is used to connect your computer to an expansion device. This is an excellent investment if you are using your computer both in and out of the office. When you return to your desk, you can then connect to your network, print reports from your computer, or use a mouse instead of your computers pointing device. Connecting cables for each of these devices every time you return to the office can be time consuming. With an expansion device, you can leave external devices connected while you are using your computer away from your desk. When you return, you can quickly connect your computer and have immediate access to all the devices. For more information, see the accessories information package that comes with the device or visit accessories.toshiba.com.
Using an Optional Toshiba Express Port Replicator with your computer
If you purchase an optional Toshiba Express Port Replicator (not shipped with your system), you can connect this device to your computers expansion port. In order to achieve a proper connection, the Toshiba Express Port Replicator must be properly aligned with your computer. To properly connect the Toshiba Express Port Replicator to your computer, see the Toshiba Express Port Replicator Users Guide or visit pcsupport.toshiba.com.

The Windows operating system is not working
If the trickle-charging does not prove effective, visit the Toshiba Web site at pcsupport.toshiba.com and see the Support Bulletin Step-Charging the computers battery (click the Ask Iris link and search for the support bulletin by name). 4 Connect the AC adaptor to a different power outlet, preferably in a different room. If the computer starts normally, there may be a problem with the AC outlet itself, or the voltage level available from it. Verify that the AC adaptor is the correct unit for your computer model. The computer may not be able to start from an AC adaptor that is rated for less current (amperage) than the computer requires, even if the rated voltage is correct, and the plug fits correctly in the DC-IN socket. The labels on the bottom of the computer and the AC adaptor show the specifications for voltage ("V") and current ("A") for each device. The voltage level must match exactly. The amperage rating of the AC adaptor must be equal to or greater than that required by the computer.
Once you are familiar with the desktop and used to the way the operating system responds to your work routine, you can easily detect if the operating system is not working correctly. For example: The operating system fails to start after the Starting Windows XP message appears. The operating system takes a long time to start. The operating system responds differently from the normal routine. The screen does not look right.
Unless a hardware device has failed, problems usually occur when you change the system in some way such as installing a new program or adding a device. If you experience any of these problems, use the options in the Startup menu to fix the problem.
Using Startup options to fix problems
If the operating system fails to start properly, you may have to change your systems configuration or verify the startup procedure to fix the problem. To do this, use the options in the Startup menu. To open the Startup menu: Restart your computer. Press F8 when your computer starts and before Windows starts loading. The Windows Advanced Options menu displays these options: Safe Mode Safe Mode (with Networking) Safe Mode (with Command Prompt) Enable Boot Logging Enable VGA Mode Last known good configuration (your most recent settings that worked) Directory Services Restore Mode (Windows domain controllers only) Debugging Mode Start Windows normally Reboot Return to OS Choices (menu)
See your Windows documentation for further explanation.
If your computer is connected to a network, the Startup menu may display different versions of Safe mode.
