, Multiple Response

1. A technician has determined that a laptop keyboard will need to be removed in order to replace the laptop’s CPU
cooling fan.

Which of the following steps will most likely be required before the technician can remove the keyboard from the laptop?
(Select TWO.)
a. The keyboard backlight will need to be toggled off by using the appropriate Fn keys.
b. The keyboard cable(s) will need to be disconnected from the ZIF socket(s).
c. The keyboard cable will need to be disconnected from the mini-PCIe slot.
d. The keyboard bezel will need to be removed.
e. The technician will need to remove the display assembly and system board.
ANSWER: b, d
FEEDBACK: a. Incorrect. The keyboard backlight component is integrated into the laptop keyboard that
illuminates the keys. The laptop will be powered off when the keyboard is removed, making
this choice irrelevant.
b. Correct. Typical laptop keyboards are connected to the system board via one or more ribbon
cables. The system board end of the ribbon cable utilizes ZIF (zero insertion force) sockets.
These cables will need to be disconnected prior to removal of the keyboard.
c. Incorrect. Laptop computers do not use mini-PCIe slots for keyboard connectivity. The mini-
PCIe slot is used for wireless and wired network adapters, SATA controllers, FireWire cards,
USB cards, and more.
d. Correct. The keyboard bezel is a part of the plastic covers of a laptop and is the cover that
surrounds the top of the keyboard. For some laptops, the case top covers the keyboard.
Regardless of whether the cover is the bezel or the case top, it will need to be removed first in
order to remove the keyboard.
e. Incorrect. The keyboard does connect to the system board; however, the system board does
not need to be removed in order to remove the keyboard. Likewise, the display adapter does
not need to be removed prior to removing a laptop keyboard.




2. Molly, an end user, connects an external monitor, external keyboard and mouse, and a wired network cable to her
laptop while working in the office. She leaves the office frequently to meet with customers and takes the laptop with her.
Disconnecting and reconnecting these external connections has become inconvenient.

Which of the following devices will allow the user to disconnect and reconnect the laptop to the external connections with
the least amount of effort? (Select TWO).
a. USB to RJ-45 dongle
b. Expansion card
c. ZIF connector
d. Port replicator
e. Docking station
ANSWER: d, e
FEEDBACK: a. Incorrect. A dongle is used to add an external port to a computer. For example, the USB to RJ-
45 dongle connects to the laptop’s USB port and provides an RJ-45 Ethernet network
connection. This device will provide only an external wired network connection.
b. Incorrect. An expansion card for a modern laptop is typically a mini-PCIe connector and is
accessed by removing an access cover on the bottom of the laptop or by removing the bottom
cover. An expansion card will provide additional connectivity but not the convenience of
connecting and disconnecting external devices.
