Q

What component allows you to keep desktop devices such as keyboard, monitor, and mouse permanently connected so they can be used by an attached laptop?

A. Docking station
B. Keyboard, video, mouse (KVM) switch
C. Print server
D. USB hub

A.

A docking station made specifically for its associated brand and model of laptop can
host desktop components permanently, regardless of whether the laptop is attached to the docking station.

When the laptop’s portability is not required, but instead use of the desktop
components is the priority, attaching the laptop to the docking station makes such components available to the laptop without separately attaching each component.

Q

When replacing your laptop’s AC adapter, which of the following purchases is acceptable to obtain the same or better results?

A. An AC adapter with a higher voltage rating than the original
B. An AC adapter with a higher wattage rating than the original
C. A DC adapter with the same voltage rating as the original
D. An AC adapter with a lower voltage and wattage rating than the original

A

B.

Think of wattage as a “bucket” of power that the attached device can draw on.

A bigger bucket simply holds more power but does not force the power on the device.

Less wattage is not advised, however.

Voltage can be thought of as the pressure behind the power to the device.

Anything but the proper voltage is dangerous for the device.

When you replace a laptop’s AC adapter, you should match the voltage ratings of the original adapter.

This also means you should use an adapter with a fixed voltage if that matches the characteristics of the original; otherwise, obtain one that automatically switches voltages at the levels needed.

Q

What should you do for a Li-ion battery that appears to charge fully but does not last as
long as the battery’s meter indicates it will last?

A. Replace the battery.
B. Exercise the battery.
C. Calibrate the battery.
D. Short the terminals to discharge the battery.

A

C.

Battery calibration for Li-ion batteries allows the powered device to drain the battery’s
power before recharging.

Battery exercising is the initial charging and discharging of nickelbased batteries so that they will function as expected.

You should never short a battery’s terminals, and replacement is a last resort when any battery has reached the end of its life.

Q

How do laptop hard drives differ from desktop hard drives?

A. Laptop hard drives use completely different standards from those used by desktop hard drives for communication with the host.
B. Laptop hard drives are solid state; desktop hard drives have spinning platters.
C. Laptop hard drives require a separate power connection; desktop hard drives are powered through the drive interface.
D. The most common form factor of a laptop hard drive is about an inch smaller than that
of a desktop hard drive.

A

D.

Laptop hard drives commonly have a 21⁄2 g form factor.

The most common form factor for desktop hard drives is 31⁄2 g.

Laptop hard drives use the same drive technologies as their desktop counterparts, such as serial and parallel ATA.

As with desktop hard drives, laptop hard drives are available in both solid-state and conventional varieties.

Unlike desktop hard drives, laptop hard drives do not have separate power connectors.
