    1. What is a Notebook Computer ?

    2. A Notebook is a portable computer

    3. Portable Computers • Laptops - largest • Notebooks - smaller • Palmtops - smallest

    4. A portable computer is much smaller and lighter than the most compact PC. • The screen and keyboard are integrated parts of the unit. • Case is small, flat design in which all the pieces fit together snugly – HEAT is a problem

    5. Ever heard of Xerox ? • In the 1970s, Alan Kay of the Xerox Palo Alto Research Center sketched the Dynabook – a vision for a wireless portable computer • Dynabook never got past sketches and a cardboard model, but the idea got out …

    6. Guess where Alan Kay ended up ?

    7. 1979 - William Moggridge of Grid Systems Corporation created the first functioning portable computer - Grid Compass Computer 1109 (find a picture) • 1109 had 340 KB memory, a die-cast magnesium case and a folding electroluminescent graphics display screen. • NASA bought 1109s at $800 for the space program.

    8. The first commercially viable machine, however, was the IBM PC Convertible, introduced in 1986.

    9. IBM PC Convertible .. • Weighed 12 lbs (5.4 kg), • sold for $3,500. • was the first portable computer with the clamshell design used in today's laptops. • The success of the PC Convertible was the catalyst for competitors like Compaq and Toshiba to switch to the clamshell design in their portable computers. And so began the era of the laptop computer.

    10. IBM PC Convertible had .. • An 8088 microprocessor • 256 kilobytes of memory • Two 3.5-inch (8.9-cm) floppy drives • An LCD display • Parallel and serial printer ports • Space for an internal modem • A software suite including basic word processing, appointment calendar, telephone/address book, and calculator software

    11. What to look for in a portable computer today … • Don’t plan to upgrade anything except memory and a PCI Card • Get a warranty • Buy light (as in not heavy) with fastest processor, active matrix display, lithium battery

    12. FYI … • In the mid 90’s one of the most exciting innovations was channel aggregation – a notebook could have 2 modem connections to speed up data transfer

    13. Extending a Notebook Cards slot into a notebook and extend the functionality, for .. • Memory • Modems • Drives PCMCIA standards define these cards.

    14. The PC Card Standard, CardBus • Memory (type 1) – 3.3 mm thick • Modems (type 2) – 5.5 mm thick • Drives (type 3) – 10.5 mm thick CardBus uses 16 bit or 32 bit operation.

    15. ExpressCard • Intended to replace PC Card • Designed to use PCI Express or USB 2.0

    16. ExpressCard • ExpressCard/34 is 34 mm wide, 75 mm long and 5 mm high. • ExpressCard/54 is 54 mm wide, 75 mm long and 5 mm high.

    17. To use PC Card and/or ExpressCard .. The Operating System needs • Socket Services • Card Services

    18. To unplug a PC Card • Windows XP : Use the unplug icon in the system tray • Windows 2000: Add/Remove Hardware

    19. Find … • A PC Card that supports gigabit ethernet • A TV Tuner PC Card • A PC Card that supports an external SATA drive

    20. Memory • SO-DIMMS • SO-RIMMS • PC Card Memory • Proprietary Memory

    21. What is an Active Matrix Display ? • A TFT (Thin Film Transistor) LCD Display

    22. The layer of rod-shaped molecules (liquid crystals) flow like liquid. • When a charge of electric current passes through the layer of liquid crystals, they align or twist, preventing or allowing the light to pass through. • Crystal Clear ?

    23. Difference between Active Matrix and Passive Matrix ? Passive matrix flat panel displays consist of a grid of horizontal and vertical wires. At the intersection of each grid is an LCD element that constitutes a single pixel. Active matrix flat panels have a transistor built into each pixel within the screen. Active matrix displays have - higher resolution, - higher contrast, - faster pixel response rates … than passive matrix LCDs.

    24. Can you find any portable computers with a passive matrix display ? Try …

    25. …. andWhat is the fastest processor in a portable computer ?

    26. Batteries … There are 4 major types of batteries used in portable computers : • Alkaline in remote controls – not used for computers today • Nickel-Cadmium (NiCd) Older, up to 12 hours to charge, memory effect, Cadmium is toxic • Nickel-metal-hydride (NiMH) Better than NiCd, but only recharged up to 500 times • Lithium-ion (Li-ion) Non-toxic but lithium highly reactive with water, lightweight, no memory effect, expensive • Direct methanol fuel cell (this is new)

    27. SO-DIMMS • 72 pin (32 bit) – outdated with FPM or EDO memory • 144 pin (64 bit) - SDRAM • 200 pin (64 bit) - SDRAM

    28. SO-RIMMS • 160 pins • RAMBUS technology

    29. PC Card Memory • Available as both CARDBUS and ExpressCard (Sometimes CARDBUS just called PCM, PC CARD …, but ExpressCard Memory will be referenced as ExpressCard)

    30. Mini PCI card Standard • Standard for notebooks to evolve from using proprietary cards and slots • Type 1 and type 2 – use a 100 pin ‘stacking connector’ • Type 3 - 124 pin stacking connector

    31. Port Replicator Vs Docking Station • Port Replicator : Allows notebook to connect to power outlet, full size monitor • Docking station : As provided by Port Replicator, but also connection to hard drive, floppy drive, DVD/CD drives

    32. Find a .. • Port Replicator • Docking Station

    33. Spend 15 minutes… • … online selecting a notebook computer for less than $1,500.

    34. Servicing your own Notebook ? All notebooks are different, usually with proprietary components, so …… Get a service manual / user manual / helpful web site

    35. Good Support ? • Lenovo and Dell have free online service manuals and phone support (through Canada) • Compaq have good web support and good phone support • Apple – Good web support, good phone support, good store support
