What is the difference between a docking station and a port replicatorA port replicator may contain a SCSI port, a networking port, PS/2 ports, USB ports, and a game port. A docking station has the same ports as a port replicator, but adds the ability to connect to PCI cards, additional hard drives, optical drives, and floppy drives.7.1.1.6 Worksheet – Research Docking Stations.7.2 Identify and describe the display components of a laptop.Describe the 4 different display components of a laptop.LCDThe LCD cutoff switch helps conserve power by extinguishing the backlight and turning off the LCD. If this switch breaks or is dirty, the LCD remains dark while the laptop is open. Carefully clean this switch to restore normal operation.LEDLED monitors use less power and have a longer lifespan than LCD monitorsOLEDOrganic LED (OLED) technology is commonly used for mobile devices and digital cameras, but can also be found in laptop concept designs. OLED monitors will become more popular as the technology improves.PlasmaPlasma displays are rarely found in laptops, because they consume a large amount of power.What is the importance of an Inverter? The inverter converts DC power to the higher voltage AC power that is required by the backlightWhat is the function of a backlight?The backlight shines through the screen and illuminates the displayDefine Cold cathode fluorescent lamp (CCFL)LCD monitors use CCFL technology for the backlight. The fluorescent tube is connected to an inverter.Sketch the location of most Wi-FI antennas in laptopsWi-Fi antennas in laptops are typically located above the screen,7.3 Identify and describe how to manage laptop power settings and options.Define Advanced Power Management (APM).Advances in power management and battery technology are increasing the time that a laptop can be disconnected from AC power.What is Advanced Configuration and Power Interface (ACPI)?ACPI has replaced APM. ACPI standards, as shown in the figure, create a bridge between the hardware and OS and allow technicians to create power management schemes to get the best performance from a laptop.What devices can be turned off to conserve battery power or the entire system?What needs to be enabled in the BIOS settings in order to allow the configuration of your power management state? ACPI power managementName the four steps to enable ACPI? Step 1. Enter BIOS setup.Step 2. Locate and enter the Power Management settings menu item.Step 3. Use the appropriate keys to enable ACPI mode.Step 4. Save and exit BIOS setup.7.3.1.3 Worksheet – Match ACPI Standards7.4 Identify and configure laptop wireless adapters and settings.What is Bluetooth?The Bluetooth technical specification is described by the Institute of Electrical and Electronics Engineers (IEEE) 802.15.1 standard.How many devices can a Bluetooth wireless device support? 10What is the most common class of Bluetooth? The most common Bluetooth network is Class 2, which has a range of approximately 33 ft (10 m).What are the three common types of IR? Line of sight - The signal is transmitted only if there is a clear, unobstructed view between devices.Scatter - The signal is bounced off ceilings and walls.Reflective - The signal is sent to an optical transceiver and is redirected to the receiving device.What are potential issues with IR?iR light cannot penetrate ceilings or walls.IR signals are susceptible to interference and dilution by strong light sources, such as fluorescent lighting.Scatter IR devices can connect without the line of sight, but data transfer rates are lower and distances are shorter.Where are wireless connection configured? To connect a laptop to a cellular WAN, you install an adapter that is designed to work with cellular networks.Define each of the following standards:Mini-PCI Commonly used by older laptops. Mini-PCI cards have 124 pins and are capable of 802.11a, 802.11b, and 802.11g wireless LAN connection standards.Mini-PCIe Most common type of wireless card in laptops. Mini-PCIe cards have 54 pins and support all wireless LAN standards. PCI express Micro* Commonly found in newer and smaller laptops, such as Ultrabooks, because they are half the size of Mini-PCIe cards. PCI Express Micro cards have 54 pins and support all wireless LAN standards.7.5 Identify and describe laptop hardware component installation and configuration.Draw a picture of the three laptop expansion cards with their below:When removing a keyboard on a laptop what must you do first? Power off the laptop, disconnect the AC adapter, and remove the batteryHow do you remove SODIMM? Step 4. Lift up to loosen the SODIMM from the slot and remove the SODIMM.7.5.1.4 Worksheet – Laptop RAMExplain Customer-replaceable units (CRUs)?Some parts of a laptop, typically called customer-replaceable units (CRUs), can be replaced by the customer. CRUs include such components as the laptop battery and RAM.What are Field-replaceable units (FRUs)?Parts that should not be replaced by the customer are called field-replaceable units (FRUs).What should you ALWAYS check before staring a repair and why?The BatteryWhat are some signs that a laptop battery may need to be replaced? What should be done to a new battery?Should be tested to make sure it is working right7.5.2.3 Worksheet - Laptop Batteries 7.5.2.5 Worksheet - Laptop Screens 7.5.2.7 Worksheet - Laptop Hard Drives Before replacing the speakers on a laptop, what should you check?If they are worth it What needs to be removed to replace a laptop motherboard?7.5.2.13 Worksheet – Build a Specialized Laptop7.6 Identify common preventive maintenance techniques used for laptops.Explain what makes laptops more likely to suffer “environmental” damage when compared to desktops.As a result, they are more likely than desktop computers to be exposed to these harmful materials and situations:What types of cleaning products are used to clean laptops?
