    Which task must be completed first for a technician to be able to configure power management states using Windows XP?

    • A.

      APM power management mode must be configured in the BIOS before ACPI can be used to configure power.

    • B.

      ACPI power management mode must be enabled in the BIOS before Windows XP can be used to configure power management.

    • C.

      APM power management mode must be disabled in the BIOS so that Windows XP can be used to configure power management.

    • D.

      All power management settings must be disabled in the BIOS so Windows can be used to manage ACPI.

    Correct Answer
    B. ACPI power management mode must be enabled in the BIOS before Windows XP can be used to configure power management.
    Explanation
    In order for a technician to configure power management states using Windows XP, the ACPI power management mode must first be enabled in the BIOS. ACPI (Advanced Configuration and Power Interface) is a standard that allows the operating system to control power management settings. By enabling ACPI in the BIOS, Windows XP will be able to access and configure power management options.

    What is the benefit of using CPU throttling in laptops?

    • A.

      It reduces the processing time needed by end-user applications.

    • B.

      It reduces CPU power consumption and heat production.

    • C.

      It reduces the amount of CPU resources needed by system applications.

    • D.

      It avoids the need to increase the clock speed of the laptop processor.

    Correct Answer
    B. It reduces CPU power consumption and heat production.
    Explanation
    CPU throttling is a technique used in laptops to reduce the power consumption and heat production of the CPU. By decreasing the clock speed of the processor, it limits the amount of power consumed and the amount of heat generated. This helps in improving the battery life of the laptop and preventing overheating, which can lead to performance issues and hardware damage. Additionally, CPU throttling allows the laptop to operate more quietly as the fans don't need to work as hard to cool down the CPU.

    What is the major difference between desktop and laptop motherboards?

    • A.

      Desktops use the AT form factor while laptops use the mini or baby AT form factor.

    • B.

      Desktop motherboards typically have a standard form factor and are interchangeable while laptop motherboards are proprietary.

    • C.

      Desktops have a variety of expansion and RAM slot designs while laptops have standard expansion and RAM slot designs.

    • D.

      Currently there is no significant difference in the motherboard form factors for the desktop and laptop.

    Correct Answer
    B. Desktop motherboards typically have a standard form factor and are interchangeable while laptop motherboards are proprietary.
    Explanation
    Desktop motherboards typically have a standard form factor and are interchangeable, meaning they can be easily replaced or upgraded with other standard-sized motherboards. On the other hand, laptop motherboards are proprietary, which means they are specifically designed for a particular laptop model and cannot be easily replaced or upgraded with other motherboards. This is a major difference between desktop and laptop motherboards, as it affects the flexibility and customization options available for each type of computer.

    What is the proper way to clean optical drives?

    • A.

      Spray ionized solution inside the drive.

    • B.

      Use an electrostatic vacuum cleaner

    • C.

      Blow the dust with compressed air from the inside.

    • D.

      Use a cleaning disc for optical drives

    Correct Answer
    D. Use a cleaning disc for optical drives
    Explanation
    The proper way to clean optical drives is by using a cleaning disc specifically designed for optical drives. These cleaning discs have small brushes or microfiber cloths that can effectively remove dust and debris from the laser lens of the drive. Spraying ionized solution inside the drive or using an electrostatic vacuum cleaner can potentially damage the delicate components of the drive. Blowing dust with compressed air may also cause the dust to spread and settle on other parts of the drive. Therefore, using a cleaning disc is the safest and most effective method for cleaning optical drives.
