  15. Laptop Components- Bottom • Battery removal latches • Docking Station connector • RAM Access panel • HD Access panel

  16. Lab • View the virtual laptop • View the real laptop

  17. Laptop Components- Open • Touchpad & pointer • Fingerprint Reader • Power • Multimedia/Volume buttons

  18. Laptop Components- Open • Wireless • Bluetooth • Number Lock • Caps Lock • HD Activity • Power • Battery • Standby

  19. Input Devices • May need drivers & configurations • Stylus • Tablet • Barcode reader • Scanner • Light pen • Web camera • PC game device • Control Panel or in All Programs

  20. Laptop Monitor • LCD or LED • LED uses less battery & thinner • Adjustments made in software • Brightness, contrast, etc • Can use external monitor • VGA port • Fn button to switch displays

  21. Docking Station • Also port replicator • Smaller than dock • No speakers • Attach laptop to this base • Has special connector • Connects to monitor, mouse, keyboard, network, etc • Can be locked in w/ key

  22. Lab • Virtual Lab with docking station

  23. Laptop vs. Desktop • Compare and contrast desktop and laptop motherboards. • Compare and contrast desktop and laptop processors. • Compare and contrast desktop and laptop power management. • Compare and contrast desktop and laptop expansion capabilities.

  24. Laptop vs. Desktop • Compare & contrast

  25. Laptop vs. Desktop • Laptop MB proprietary • SoDIMM

  26. Laptop vs. Desktop- CPU • Laptop CPU designed for less power & heat • CPU Throttling • Changes speed to reduce heat & power • Allows for longer use on battery power • Mobile processors • May be less speed

  27. Laptop vs. Desktop- Power Options • Desktop • Always plugged in • Battery keeps BIOS/clock running • Laptop • DC power (AC to DC convertor) • Advanced Power Management (APM) OLD • Bios controlled settings • Advanced Configuration and Power Interface (ACPI) • The OS controls power management

  28. Laptop vs. Desktop- Expansion • Desktop • Internal bays of 3.5” & 5.25” • PCI Slots • USB, FireWire • Laptop • PC Card expansion- OLD • Hot-swap bays • USB, FireWire

  29. Types of Expansion- Storage • Storage Devices • Magnetic • Moving parts • Flash • SSD • Optical • CD- 700MB • DVD- 8.5GB per side • BD- 25GB per side

  30. Types of Expansion- Slots • PCMCIA/PC Card- OLD • All 54mm wide • Type I • 16-bit, slow, 3.3mm thick • PDA memory expansion only • Type II • 16 or 32-bit, 5.0mm thick • I/O devices like modems with dongles • Type III • 10.5mm thick • I/O devices without dongle use

  31. Types of Expansion- Slots • PC ExpressCards • Replaced PCMCIA • Faster throughput • 34 or 54mm wide, 5mm thin • Hot-pluggable • Replaced by USB 2.0/3.0

  32. How to Configure Laptops • Describe how to configure power settings. • Describe the safe installation and removal of laptop components.

  33. Configure Power Settings- BIOS • ACPI Standards • Help create a power scheme (plan) to maximize battery/computer performance • In BIOS • Under Power • Must be enabled in order to configure in Windows

  34. ACPI States • S0- On & CPU running • S1- CPU/RAM get power, unused devices not • S2- CPU off • S3- Suspend (XP)/Sleep (Vista/7), RAM gets power • S4- Hibernate, RAM contents saved to file in HD • S5- Off

  35. Configure Power Settings- OS • In Control Panel, Power Options • Hard drive • Display • Shut Down, Hibernate, and Suspend/Sleep modes • Low-battery warnings • What do you think consumes a lot of the battery power in laptops? • Hard drive & Display

  36. Power Schemes/Plans • Use preset or customize

  37. Laptop Power Options • XP • Standby – Docs & apps saved in RAM; powers on quickly • Hibernate – Docs & apps saved to a temp file on HD; takes a little longer than Standby to power on • Vista/7 • Sleep – Just like Standby • Hibernate
