  1. Chapter 20 Notebooks and PDAs

  2. You Will Learn… • How to support, upgrade, and add peripheral devices to notebooks • About technologies relating to personal digital assistants (PDAs)

  3. Notebook Computers

  4. Notebook Computers • Use same technology as PCs, but with modifications • Use less power • Take up less space • Endure movement • Use thin LCD panels for display • Use small memory modules and CPUs

  5. Notebooks versus PCs • Notebooks • Generally purchased as a whole unit; not likely to upgrade hardware and OS • Tend to be proprietary • Have some universal support issues, but procedures vary between brands • Cost more than comparable PCs • PCs • Highly modular • Components can be interchanged, upgraded, and enhanced

  6. Windows 98 Notebook Features • Multilink Channel Aggregation • ACPI (Advanced Configuration and Power Interface) • Improved power management • Improved support for PC Cards • Microsoft Exchange

  7. Windows 2000Notebook Features • Stronger power management and security features than Windows 98 • Offline Files • Hibernate mode • Improved battery support • Hot-swapping of IDE devices and floppy disk external drives • Folder redirection

  8. Windows XP Notebook Features • Power management features that make mobile computing easier • Ability to create hardware profiles

  9. Creating a Hardware Profile

  10. Power Management • Notebook can be powered by a battery pack or an AC adapter connected to a power source • Length of time a battery pack can power the notebook before being recharged depends on: • Quality of the battery • Power consumption (determined by devices being used) • How power is being managed • Goal • Minimize power consumption to increase time before battery pack needs recharging (eg, hibernation)

  11. Power Management Properties

  12. Hibernate Tab of Power Management

  13. Advanced Tab of Power Management

  14. Advanced Tab of Power Management

  15. Exchanging the Battery Pack

  16. Power Options Properties

  17. Types of Memory Used by Notebooks • 72-pin SO-DIMMs (small outline DIMMs) • Support 32-bit data transfers • Use FPM or EDO • Could be used as single modules in 386 or 486 machines; must be used in pairs in Pentium machines • 144-pin SO-DIMMs • Support 64-bit data transfers • Use EDO and SDRAM • Can be used as single modules in Pentium machines continued…

  18. Types of Memory Used by Notebooks • 160-pin SO-RIMM • Uses a 64-bit data path and Rambus technology • Credit card memory • Can only be used for memory

  19. Types of Memory Used by Notebooks

  20. Upgrading Memory

  21. Upgrading Memory

  22. Upgrading Memory

  23. Hard drive LCD panel Motherboard CPU Keyboard PC Card socket assembly CD-ROM drive Floppy drive Sound card Pointing device AC adapter Battery pack DC controller Other Field Replaceable Units for Notebooks

  24. Comparing Hard Drives

  25. Replacing a Hard Drive

  26. Ways to Connect Peripheral Devices to Notebooks • Port on the notebook itself • Port replicator • Docking station • PC Cards (most popular) • USB ports

  27. Ports on the Back of a Notebook

  28. Port Replicator

  29. Docking Station

  30. PC Cards

  31. PC Cards • Special bus expansion slots that connect to the 16-bit PCMCIA I/O bus on notebook motherboard • Four standards • Latest specification: CardBus • Improves I/O speed • Increases bus width to 32 bits • Supports lower-voltage PC Cards while maintaining backward compatibility • Three standards that pertain to size (Type I, Type II, and Type III)

  32. PC Cards • OS must provide two services • Socket service • Card service • Might contain a data cable to an external drive, or might be self-contained • Other smaller slots include one for a Secure Digital (SD) Card and one for a Compact Flash Card • Can be hot-swapped • Can interface with a network

  33. Two Examples of PC Cards

  34. Connecting the Phone Line to the Modem PC Card

  35. Using a PC Card to Interface with a Network

  36. Hot-Swapping a PC Card

  37. Adding Devices with a USB Port • Popular way of adding devices to notebooks • Easy installation

  38. Adding Devices with a USB Port

  39. Online Resources for Troubleshooting Notebooks • Apply same troubleshooting guidelines as for desktop PCs • Be aware of warranty issues • Loaded OS and hardware configuration are specific; see documentation for details

  40. PDAs • Small, handheld computers with their own OS and applications • Battery powered • Use either a grayscale or color active matrix or dual-scan passive matrix display • Can sometimes benefit from additional memory • Include a stylus • Options include applications buttons, AC/DC adapter, fold-out keyboard option

  41. Example of a PDA

  42. Fold-out Keyboard Option

  43. Considerations When Purchasing a PDA • What applications come with it; what can be added later? • Easy to use? Thorough documentation? • Is synchronization easy? • What support is available from manufacturer? • Type of batteries? Battery life? continued…

  44. Considerations When Purchasing a PDA • Can it use e-mail and the Web? Extra hardware or software required? • Can additional devices be purchased? • What OS does it use? How easy to use? • What is the warranty? • What is the price?

  45. Battery Life on a PDA • Short battery life is the one largest complaint; risk losing data and applications if battery runs all the way down • Use cradle and adapter

  46. Applications on a PDA • Some come with all application software preinstalled • Some require user to download applications at additional cost • Some support applications that come preinstalled and cannot download others • Some allow downloading e-mail or Web site content • Some access Internet directly by way of a modem or wireless connection

  47. Connecting a PDA to a PC • Synchronization • Process by which PDA and PC “talk” to each other through universal cradle, cable, and USB or serial connection, or wireless technology • Capabilities • Backup information from PDA to PC • Work with PDA files on PC and download applications from Web

  48. Troubleshooting PDAs • USB or serial cable plugged in at both ends? • Verify that USB controller is working in Device Manager with no conflicts • USB or serial port enabled in CMOS setup? • PDA turned on? • Check PDA documentation • Uninstall and reinstall PDA software on the PC • Check Web site of manufacturer

  49. PDA Manufacturers and Operating Systems • Principal difference between the two main OSs for PDAs is in the applications they support • Pocket PC • More versatile; better for downloading and running applications • Palm OS • Less complex • Easier to use • Best choice for simple tasks
