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.

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 Name: Class: Date: Chapter 01: Taking a Computer Apart and Putting It Back Together Copyright Cengage Learning. Powered by Cognero. Page 2 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. Incor rect. 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 conve nience of connecting and disconnecting external devices. c. Incorrect. ZIF stands for zero insertion force and is an internal connector used in a laptop to connect the keyboard and touchpad to the motherboard. d. Correct. A port replicator typically connects to a laptop using a single USB port and provides the convenience of connecting external connections such as monitors, USB devices, and network patch cables. The port replicator isn’t proprietary, meaning it is designed to work with any laptop with an open USB port. e. Correct. A docking station provides the same functionality as that of a port replicator but is typically proprietary, meaning it is designed for a specific brand and model of laptop. Older docking stations are connected to a laptop through a proprietary docking port on the bottom of the laptop.

A technician needs to service a laptop computer that is experiencing an intermittent problem with the display. Which of the following will be most effective at helping the technician complete the work in a timely and efficient manner? (Select TWO). a. Provide the customer with a laptop to use while the failing unit is being repaired. b. Document and label the location of the screws and cables before removing them. c. Compare the system board display connections with a properly functioning laptop. d. Organize and place all parts and screws and in one place. e. Charge the laptop battery pack so it is ready to return to the customer with a full charge. ANSWER: b, d FEEDBACK: a. Incorrect. Providing a loaner computer to the customer while hers is being repaired is often done but will not help the technician complete the work in a timely fashion. b. Correct. While most desktop computers contain only one or two types of screws, a laptop may have a variety of screws and washers in various sizes and lengths. It is imperative that a technician document and label screws and cables before removing them. Inserting a screw that is too long may penetrate a cable or circuit board and cause damage. Inserting a screw that is the wrong size can also strip the threads, causing the correct -sized screw not to tighten properly. Documenting and labeling locations will assist in reassembling the unit. c. Incorrect. If a laptop is disassembled without documenting the locatio n of cables and connectors, this choice may be an option. The question does not state that the unit was already disassembled. d. Correct. After documenting and labeling the location of the parts and screws, the technician needs to organize them and keep them in one place. Doing so will assist in reassembling the unit. e. Incorrect. Making sure the battery pack is fully charged after a repair is proper etiquette Name: Class: Date: Chapter 01: Taking a Computer Apart and Putting It Back Together Copyright Cengage Learning.

You are troubleshooting a laptop with multiple sticking keys that result in misspelled words while the user types. Other than several sticking keys, the laptop appears to be functioning properly. You have cleaned the keyboard with compressed air, but the problem persists. After removing one of the key tops, it becomes apparent that a liquid was spilled into the keyboard. Which of the following is the next step in resolving the issue of sticking keys? a. Replace the keyboard with a compatible keyboard. b. Disconnect and reseat the keyboard ribbon cable. c. Clean the keyboard keys with a contact cleaner. d. Replace the laptop system board and reseat all connections. ANSWER: c FEEDBACK: a. Incorrect. Replacing the keyboard may be the only option; however, for spills you can first try to use a contact cleaner on the keyboard’s keys and contacts. b. Incorrect. Reseating the keyboard ribbon cable can be an effective fix when the contacts become corroded or oxidized. Corrosion or oxida tion will usually exhibit intermittent connectivity problems. The question states there was obvious evidence of a spill into the keyboard, which will require the keys on the keyboard to be cleaned with a contact cleaner or similar product. c. Correct. Contact cleaner can be used to clean a keyboard in which liquid has been spilled. Contact cleaners readily evaporate without leaving any residue. If the keys continue to stick, you will need to replace the keyboard. d. Incorrect. A system board replacement would be an option if the amount of liquid were sufficient enough to leak from the keyboard down to the system board. The question states that other than sticking keys, the system functions properly.
