CardBus A PCMCIA specification that improved on the earlier PC Card standards
Docking Station A device that receives a notebook computer and provides additional secondary storage and easy connection to peripheral devices
ExpressCard The latest PCMCIA standard for notebook I/O cards that uses the PCI Express and USB 2.0 data transfer standards.
Hardware The physical components that constitute the computer system, such as the monitor, the keyboard, the motherboard, and the printer
PC Card / PCMCIA A credit card sized adapter card that can be slid into a slot in the side of many notebook computers and is used by modems, network cards, and other devices.
Port Replicator A device designed to connect to a notebook computer in order to make it easy to connect the notebook to peripheral devices
Notebooks/Netbooks Portable computers, typically rely on batteries for power
Servicing Considerations •Notebooks (and replacement parts) are more expensive •Notebooks are highly proprietary units
Warranty usually offered for a year, can be voided under certain conditions
Identify the factors to consider that generally apply more to notebooks than to desktop computers OEM,Service Manual, Diagnostic Software, Built OS, Replacement parts
Identify the ways a warranty can be voided. If someone other than an authorized service center services the notebook
Service Manuals Manufacturer, 3rd Party, User Manual
Diagnostic Tools may be provided by the OEM, tests certain components
What is an OS build? The customized installation of the OS that was pre-installed at the factory
Recovery Disks/Partitions Content Varies by Manufacturer
OS Upgrades usually never upgraded, original OS should be sufficient for system life
Notebook Care More Susceptible to Damage and requires a higher level of Preventive Maintenance
Notebook Security oAnti-theft Devices (1 in 14 chance of being stolen or lost) oPassword Protected and employ acceptable Fault Tolerance
Identify the difference between a Port Replicator and a Docking Station? Docking station provides additional slots for adding secondary storage devices and expansion cards
Standard Connections video, keyboard, mouse, USB & network
PCMCIA Cards/Slots various types of I/O card slots, different standards
PC Cards o(oldest, based on 16-bit ISA) oCategories: Type I (smallest), Type II, and Type III (largest)
Card Bus o(based on 32-bit PCI standards) oOlder PC Cards function in Card Bus slots (but not vice versa)
Express Card onewest PCMCIA Standard, comparable to PCIe technology in desktops oTwo sizes: Express Card/34 and Express Card/54 oNot backward compatible with the older two standards
Most PCMCIA cards are hot swappable the service should be stopped before R&R
Newer/lighter notebooks have more USB and less card slots
Mini PCI and PCI Express o Internal slots for expansion cards o Based on desktop PCI Express standard, smaller form factor
Which PCMCIA card is up to 10.5mm thick and could be a portable disk drive? Type III
What standards are PCMCIA ExpressCards designed to use? PCI express bus standard or the USB 2.0
Two types of Card Services oSocket Service – establishes/disconnects communication between card and notebook oCard Service – provides the device driver (after the socket is created)

Which Vista power-saving state saves all work to the hard drive and powers down the system? Hibernation
Replacing or Upgrading Parts oAuthorized Service Center oSubstitute an external part for an internal part oReplace the Item
When substituting an external part for an internal part what must be done in CMOS/BIOS setup? disable that internal device
Memory oPerformance Improvement oShared or Dedicated Video Memory
Types of memory SO-DIMMs/SO-RIMMs PC Card Proprietary MicroDIMM (smaller than SO-DIM)
SO-DIMMs/SO-RIMMs •Notches identify types (identical in function to desktop memory)
Hard Drive different form factor than desktop
