If you choose to stop in Standby or Hibernation mode, you can return to where you left off the next time you start up the computer. (See “Power Management” in Chapter 3 for more information.) Operating Your Computer 2-3 Using the Keyboard Your keyboard has all the standard functions of a full-sized computer keyboard plus a Fn key added for specific functions. The standard functions of the keyboard can be further divided into four major categories: Typewriter keys Cursor-control keys Numeric keys Function keys Typewriter Keys Typewriter keys are similar to the keys on a typewriter. Several keys are added such as the Ctrl, Alt, Esc, and lock keys for special purposes. When the lock keys (Caps Lock, Num Lk, and Scroll Lk) are pressed, their corresponding indicators light up. The Control key is normally used in combination with other keys for program-specific functions. The Alternate key is normally used in combination with other keys for program-specific functions. The Escape key is usually used for stopping a process. Examples are exiting a program and canceling a command. The function depends on the program you are using. 2-4 Operating Your Computer Cursor-Control Keys NOTE: The word “cursor” refers to the indicator on the screen that lets you know exactly where on your screen anything you type will appear. It can take the form of a vertical or horizontal line, a block, or one of many other shapes. Numeric Keypad A 15-key numeric keypad is embedded in the typewriter keys as shown next: Operating Your Computer 2-5 Numeric keys facilitate entering of numbers and calculations. When Num Lock is on, the numeric keys are activated; meaning you can use these keys to enter numerals. NOTES: l When the numeric keypad is activated and you need to type the English letter in the keypad area, you can turn Num Lock off or you can press Fn and then the letter without turning Num Lock off. l Some software may not be able to use the numeric keypad on the computer. If so, use the numeric keypad on an external keyboard instead. Euro Symbol You can press the Euro dollar sign on the keyboard. To press the Euro sign on the keyboard, hold down either of the Alt keys and type 0128 on the numeric keypad of your keyboard. To press the Euro sign on an UK keyboard, hold down the Alt Gr key and press 4 (which has an Euro sign on it). Windows Keys The keyboard has two keys that perform Windows-specific functions: Windows Logo key and Application key. The Windows Logo key opens the Start menu and performs software-specific functions when used in combination with other keys. The Application key usually has the same effect as a right mouse click. (See your Windows manual for more information.) Function Keys On the top row of the keys are the function keys: F1 to F12. Function keys are multi-purpose keys that perform functions defined by individual programs. 2-6 Operating Your Computer Fn Key The Fn key, at the lower left corner of the keyboard, is used with another key to perform the alternative function of a key. The letter “Fn” and the alternative functions are identified by the color of blue on the keytop. To perform a desired function, first press and hold Fn, then press the other key. Hot Keys Hot keys refer to a combination of keys that can be pressed any time to activate special functions of the computer. Most hot keys operate in a cyclic way. Each time a hot key combination is pressed, it shifts the corresponding function to the other or next choice. You can easily identify the hot keys with the icons imprinted on the keytop. The hot keys are described next. Key Description Switches the optional keyboard backlight function on/off with 10 levels of brightness in-between. Decreases the sound volume. Increases the sound volume. Decreases the LCD brightness. Increases the LCD brightness. Enabled/Disabled the Touchpad. Switches LCD on and off. Operating Your Computer 2-7 Key Description Switches the display output to one of the following when an external device is connected. Upon booting the system with CRT: LCD CRT LCD & CRT NOTES: If the display mode is set to 256 colors or lower, or in DOS mode, there will be only two modes for selecting: CRT only and LCD & CRT. This function only applies to Plug & Play CRT monitors. Serves as the sleep button that you can define with Windows’ Power Management. (See the “Power Management” in Chapter 3.) Enabled/Disabled the LCD Backlight On/Off. Switches the optional GPS function on and off. 2-8 Operating Your Computer Using the Touchpad CAUTION: Do not use a sharp object such as a pen on the touchpad. Doing so may damage the touchpad surface. NOTES: By default, the touchpad is disabled. Use the Fn+F7 hot keys to enable/disable this function. The touchpad indicator found on the keyboard panel glows red when it is disabled. For optimal performance of the touchpad, keep your fingers and the pads clean and dry. When tapping on the pad, tap lightly. Do not use excessive force. The touchpad is a pointing device that allows you to communicate with the computer by controlling the location of the pointer on the screen and making selection with the buttons. The touchpad consists of a rectangular pad and four buttons. To use the touchpad, place your forefinger or thumb on the pad. The rectangular pad acts like a miniature duplicate of your display. As you slide your fingertip across the pad, the pointer (also called cursor) on the screen moves accordingly. When your finger reaches the edge of the pad, simply relocate yourself by lifting the finger and placing it on the other side of the pad. Here are some common terms that you should know when using the touchpad: Operating Your Computer 2-9 Term Action Point Move your finger on the pad until the cursor points to the selection on the screen. Click Press and release the left button. –or– Tap gently anywhere on the pad. Doubleclick Press and release the left button twice in quick succession. –or– Tap twice on the pad rapidly. Drag and drop Press and hold the left button, then move your finger until you reach your destination (drag).

In addition, GPRS provides permanent on-line connection. To use GPRS, you must have a subscription to the function with a service provider that supports GPRS. Configuring a GPRS Connection To connect to a GPRS network, you must configure a connection for that service on your computer. Using the GPS NOTE: To take advantage of the GPS feature, the PCI-952 driver supplied with your computer must be installed (see chapter 6). Navigation and positioning are crucial to so many activities and yet the process has always been quite cumbersome. To try to figure out where you are and where you are going, you need GPS technology. The Global Positioning System (GPS) is a worldwide radio-navigation system formed from a constellation of 24 satellites and their ground 2-24 Operating Your Computer stations. GPS uses these "man-made stars" as reference points to calculate positions accurate to a matter of meters. In fact, with advanced forms of GPS you can make measurements to better than a centimeter! In a sense it is like giving every square meter on the planet a unique address. Here's how GPS works in five logical steps: The basis of GPS is "triangulation" from satellites. To "triangulate," a GPS receiver measures distance using the travel time of radio signals. To measure travel time, GPS needs very accurate timing that it achieves with some tricks. Along with distance, you need to know exactly where the satellites are in space. High orbits and careful monitoring are the secret. Finally you must correct for any delays the signal experiences as it travels through the atmosphere. Five broad categories of GPS application: Location – determining a basic position Navigation – getting from one location to another Tracking – monitoring the movement of people and things Mapping – creating maps of the world Timing – bringing precise timing to the world Operating Your Computer 2-25 2-26 Operating Your Computer CHAPTER Managing Power Your computer operates either on external AC power or internal battery power. This chapter tells you how you can effectively manage power. To maintain optimal battery performance, it is important that you use the battery in the proper way. The topics in this chapter include: What is an AC adapter How to charge the battery pack When and how to initialize the battery pack How to check the battery level How to replace the battery pack What happens when the battery is low and what actions to take What is Power Management How to save power AC Adapter CAUTION: The AC adapter is designed for use with your computer only. Connecting the AC adapter to another device can damage the adapter. l The AC power cord supplied with your computer is for use in the country where you purchased your computer. If you plan to go overseas with the computer, consult your dealer for the appropriate power cord. l When you disconnect the AC adapter, disconnect from the electrical outlet first and then from the computer. A reverse procedure may damage the AC adapter or computer. l When unplugging the connector, always hold the plug head. Never pull on the cord. The AC adapter serves as a converter from AC (Alternating Current) to DC (Direct Current) power because your computer runs on DC power, but an electrical outlet usually provides AC power. It also charges the battery pack when connected to AC power. The AC adapter operates on any voltage in the range of 100 ~ 240 V AC. 3-2 Managing Power Battery Pack The battery pack is the internal power source for the computer. It is rechargeable using the AC adapter. The operating time of a fully charged battery pack depends on how you are using the computer. When your applications often access peripherals, you will experience a shorter operating time. NOTE: Care and maintenance information for the battery is provided in the “Battery Pack Guidelines” section in Chapter 7. Charging the Battery Pack NOTES: l Charging will not start if the battery’s temperature is below 0 °C (32 °F) or above 50 °C (122 °F). l The charging process will stop and the Battery Charge Indicator flashes amber when the battery’s temperature gets above 60 °C (140 °F). If this happens, the battery pack may be damaged. Please contact your dealer. l During charging, do not disconnect the AC adapter before the battery has been fully charged; otherwise you will get a prematurely charged battery. To charge the battery pack, connect the AC adapter to the computer and ) on the computer an electrical outlet. The Battery Charge Indicator ( glows amber to indicate that charging is in progress. You are advised to keep the computer power off while the battery is being charged. When the battery is fully charged, the Battery Charge Indicator glows green. It takes approximately 197 minutes to charge the battery pack to 80% capacity and four or more hours to fully charge the battery pack when the computer is off. CAUTION: After the computer has been fully recharged, do not immediately disconnect and reconnect the AC adapter to charge it again. Doing so may damage the battery. NOTE: The battery level may automatically lessen due to the self-discharge process (0.21% per day), even when the battery pack is fully charged (100%). This happens no matter if the battery pack is installed in the computer. Managing Power 3-3 Initializing the Battery Pack You need to initialize a new battery pack before using it for the first time or when the actual operating time of a battery pack is much less than expected. Initializing is the process of fully charging, discharging, and then charging. It can take several hours. 1. Make sure the computer power is turned off. Connect the AC adapter to fully charge the battery pack. 2. After the battery pack is fully charged, turn on the computer. 3. Disconnect the AC adapter and leave the computer on until the battery is fully discharged. The computer will shut down automatically. 4. Connect the AC adapter to fully charge the battery pack. Checking the Battery Level NOTE: Any battery level indication is an estimated result. The actual operating time can be different from the estimated time, depending on how you are using the computer. You can check the approximate battery level using the battery meter function of the operating system. To read the battery level in Windows, icon on the taskbar. (Click the icon if the computer is click the using AC power.) 3-4 Managing Power Replacing the Battery Pack CAUTION: z There is danger of explosion if the battery is incorrectly replaced. Replace the battery only with the computer manufacturer’s optional battery packs. Discard used batteries according to the dealer’s instructions. z Do not attempt to disassemble the battery pack. If you often rely on battery power for a long period of time while traveling, you may consider the purchase of an additional battery pack from your dealer and keep it with you in a fully charged state as a backup. To replace the battery pack, follow these steps: 1. Make sure the computer is not turned on or connected to AC power. 2. Remove the four screws and lift the battery pack compartment cover to take it off the computer. 3. Pull on the ribbon and take the battery pack off the computer. 4. Insert the new battery pack into the compartment. Managing Power 3-5 5. Replace the battery pack compartment cover and secure the four screws. Battery Low Signals and Actions Battery Low occurs when the battery has approximately 10% (Windows default setting) of its charge remaining. The computer gives warning ) blinks red to beeps or messages and the Battery Low Indicator ( alert you to take actions. NOTE: You can set up your threshold and signals of Battery Low under Windows. Immediately save your data upon Battery Low. The remaining operating time depends on how you are using the computer. If you are using the audio subsystem, hard or CD/DVD drives, the battery might run out of charge very quickly. Always respond to Battery Low by placing your computer on Standby or Hibernation mode, turning off the computer, or connecting the AC adapter. If you do not take any action, the computer will automatically hibernate and turn off. CAUTION: If you fail to save your data when the battery completely runs out of charge, then you lose your data. 3-6 Managing Power Power Management Your computer supports ACPI (Advanced Configuration and Power Interface) for power management. The power management feature allows you to reduce the power consumption for energy saving. With an ACPI-compliant operating system such as Windows 2000 and Windows XP, power supply to different computer components is controlled on an as-needed basis. This allows maximum power conservation and performance at the same time. In general, Windows’ power management works in this way: What … When … Power to the hard disk is turned off When the hard disk has been idle for a set period. Power to the display is turned off When the display has been idle for a set period. The computer enters Standby mode. When the entire system has been idle The hard disk and display are turned for a set period. off and the entire system consumes When you press Fn+F10. * less power. When you close the cover. * When you press the power button. * The computer enters Hibernation mode. (See the next subsection for more information.) When you press the power button. * When you press Fn+F10. * When you close the cover. * * depends on your settings in Windows. For detailed information on power management, see Windows’ Help. Managing Power 3-7 Hibernation Hibernation is a very useful feature. People frequently open many applications when they use computers. It takes some time to get all these applications open and running, and normally they all have to be closed before the system can be turned off. When you use the hibernation feature, you do not have to close the applications. The computer stores the state of your computer to a file on the hard disk and then shut down. The next time you turn on your computer, you return to exactly where you left off. 3-8 Managing Power Power-Saving Tips In addition to your computer’ s automatic power management, you can do your part to maximize the battery’ s operating time by following these suggestions. Do not disable Power Management. Decrease the LCD brightness to the lowest comfortable level. Disable the parallel and serial ports if no devices are connected to these ports. (See “Components Menu” in Chapter 5.) If you work with an application that uses the serial port or features wireless connectivity (LAN/modem/GPS), exit the application when you finish using it. Turn off the computer when you are not using it. Managing Power 3-9
