| Question | Answer |
|---|---|
| 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) |
| Socket Service | establishes/disconnects communication between card and notebook |
| Card Service | provides the device driver (after the socket is created) |
| Wireless Connections | WiFI (802.11 b/g/n), Bluetooth, Cellular |
| WiFi (802.11 b/g/n) | LAN/WAN connection Ad Hoc Network – PC to PC Infrastructure Network – PC to Access Point |
| Bluetooth | peripheral connection |
| Cellular | WiMax (802.16) or mobile phone technology |
| What are the options for powering a notebook? | AC Adapter, DC Adapter, and a battery pack |
| Managing Power | •Notebooks typically have at least two power schemes (Control Panel): on AC and on DC •Battery Types: Ni-Cad, NiMH and, the newest technology: Lithium Ion (lasst 4-5 years) •OS/CMOS Setup Options (most laptops are ACPI compliant) |
| 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 |
| How wide is a notebook hard drive? (What is the Form Factor?) | 2.5 inches wide. Proprietary form factors |
