All rights reserved.Cisco Public ITE PC v4.0 Chapter The Components of a Laptop Common laptop features:  Small and portable  Integrated LCD display screen in lid  Integrated keyboard  AC power source or rechargeable battery  Hot-swappable drives and peripherals  Some type of docking station or port replicator to connect to peripherals  A port replicator is also a device that allows the notebook user to interface with devices like an external monitor, external keyboard, and external mouse.  The port replicator duplicates the ports that are already on the notebook like the parallel and serial ports. It may also provide a couple more ports for devices such as a joystick or MIDI (Musical Instrument Digital Interface).  The key difference between the docking station and the port replicator is that the docking station provides 1 or 2 PCI slots for add-in card devices. The port replicator does not.

© 2006 Cisco Systems, Inc. All rights reserved.Cisco Public ITE PC v4.0 Chapter Compare Laptop Components and Desktop Components  Desktop components tend to be standardized. They usually meet universal form factors using the AT or baby AT form factor.  Laptop manufacturers focus on refining laptop components to make them more efficient and compact; as a result, laptop components are proprietary.  You may not be able to use components made by one laptop manufacturer to repair a laptop made by another manufacturer.

© 2006 Cisco Systems, Inc. All rights reserved.Cisco Public ITE PC v4.0 Chapter Compare Laptop Components and Desktop Components  Laptops contain PC Card or PC ExpressCard slots to add functionality such as more memory, a modem, or a network connection. These are used use to achieve similar expansion capabilities as desktops.PC ExpressCard –PC Cards come in three types: Type I cards (3.3mm thick) are mainly used to add memory, Type II cards (5mm thick) are generally used for network adapters, and Type III cards (10.5mm thick) are often used for hard drives. –ExpressCard is the next generation of the PC Card. The numbers indicate the card's width: ExpressCard/34 devices are 34mm wide; ExpressCard/54 cards are 54mm wide. Aside from being smaller than existing PC Cards, ExpressCards promise data-transfer rates that are twice as fast. That faster speed means the cards can be used for high-bandwidth interfaces, such as Gigabit Ethernet ports and HDTV tuners.

© 2006 Cisco Systems, Inc. All rights reserved.Cisco Public ITE PC v4.0 Chapter Configure Laptops  To allow applications and processes to run smoothly: Configure and allocate system resources Install additional components and plug-ins Change environmental settings to match software requirements.  A laptop can be customized for specific purposes by adding external components.  Adding external components is usually accomplished through the use of Plug and Play, but occasionally driver installation and additional configuration may be required.  Follow safe removal procedures when disconnecting hot- swappable and non-hot-swappable devices.  Function keys change functionality such as turning on and off wireless radio or sending output to an external projection system.

© 2006 Cisco Systems, Inc. All rights reserved.Cisco Public ITE PC v4.0 Chapter 6 30 Configure Laptop Power Settings The CPU and RAM are off. The contents of RAM have been saved to a temporary file on the hard disk. This mode is also called “Saved to Disk”. In Windows XP, this state is known as the Hibernate mode. S4 The CPU is off, but the RAM is refreshed. The system is in a lower power mode than S1. S2 The computer is off and nothing has been saved. S5 The CPU is off, and the RAM is set to a slow refresh rate. This mode is often called “Save to RAM”. In Windows XP, this state is known as the Standby mode. S3 The CPU is not running. However, the CPU and RAM are still receiving power. S1 The computer is on and the CPU is running. S0 ACPI Standards—Advanced Configuration and Power Interface

© 2006 Cisco Systems, Inc. All rights reserved.Cisco Public ITE PC v4.0 Chapter 6 31 Checking the ACPI Settings in the BIOS Here are the steps to check the ACPI settings in the BIOS: 1.Enter BIOS setup by pressing the appropriate key or key combination while the computer is booting. Typically this is the Delete key or the F2 key, but there are several other options. 2.Locate and enter the “Power Management settings” menu item. 3.Use the appropriate keys to enable ACPI mode. 4.Save and Exit BIOS setup.

All rights reserved.Cisco Public ITE PC v4.0 Chapter Mobile Phone Standards Internet Standard Short Message Service (SMS) Multimedia Message Service (MMS) Packet Switching Used for text messaging Used for sending and receiving photos and videos Used for accessing the Internet Purpose

© 2006 Cisco Systems, Inc. All rights reserved.Cisco Public ITE PC v4.0 Chapter Mobile Phone Standards First-generation phones (1G) primarily used analog standards, including Advanced Mobile Phone System (AMPS) and Nordic Mobile Telephone (NMT). (1980s) The second generation (2G) of cell phones was marked by a switch from analog to digital standards. Second-generation cell standards included Global System for Mobile (GSM), Integrated Digital Enhanced Network (iDEN), and Code Division Multiple Access (CDMA). (1990s)

© 2006 Cisco Systems, Inc. All rights reserved.Cisco Public ITE PC v4.0 Chapter Mobile Phone Standards Third-generation standards (3G) enable cell phones to go beyond simple voice and data communications. It is now common for cell phones to send and receive text, photos, and video. It is also common for 3G cell phones to access the Internet and to use the Global Positioning System (GPS). Fourth-generation (4G) standards have been championed by many users, in response to the availability of increased data rates. Higher data rates will allow users to download files, such as video and music, faster than what was available with standards of previous generations.

All rights reserved.Cisco Public ITE PC v4.0 Chapter Proper Cleaning Procedures  Follow proper cleaning procedures to clean a laptop.  CAUTION: Do not spray cleaning solution directly onto the LCD display. Use products specifically designed for cleaning LCD displays. Use a soft, lint-free cloth with an approved cleaning solution to avoid damaging laptop surfaces. Apply the cleaning solution to the lint-free cloth, not directly to the laptop. Use a lint-free cotton cloth and wipe CDs and DVDs from the center outward.  Keyboard  Ventilation  LCD display  Touch pad  Floppy drive  Optical disk drive  Use cleaning disc  CD or DVD disc
