You need to replace the hard disk in your laptop computer. Which of the following hard drive sizes would you likely choose for the laptop?

2.5" Notebook hard drives and SSD drives are typically 2.5". 3.5" drives are normal sized drives for desktop computers. 5.25" are older hard drives and floppy drives.

A technician is tasked with increasing the RAM memory on a laptop by adding a SODIMM module to an empty memory slot. Which of the following processes will seat the module in the slot?

Align the notch on the long side of the memory module with the rise in the memory slot. Insert the module pins into the slot at a 45-degree angle. Rotate the module by pressing down until the side hold-down clips snap into place. Install SODIMM by aligning the notch on the long side of the memory module with the rise in the memory slot, inserting the module pins into the slot at a 45-degree angle, and rotating the module by pressing down until the side hold-down clips snap into place. Aligning the notch on the long side of the memory module with the rise in the memory slot, inserting the module pins into the slot at a 90-degree angle to the motherboard, and pressingdown until the side hold-down clips snap into place is the process for installing DIMM memory in a desktop computer. SODIMM memory is never added using the expresscard slot. Adding mounting pegs to the side of the memory module, attaching the ribbon cable, and pressing into place until the mounting clips catch the mounting pegs is the process for installing a hard drive in a laptop.

You have removed the bezel from a notebook display that has stopped functioning. You see a DC-to-AC power inverter at the base of the screen. Which of the following BEST describes the type of display you are working with?

An LCD display that uses CCFL backlighting. The inverter looks like a long, rectangular circuit board and is used to convert DC power into the AC power used by the fluorescent tubes for the CCFL backlighting. The inverter is usually located at the base of the screen. LED backlighting does not use a power inverter.

A technician is tasked with replacing a Wi-Fi antenna in a laptop computer. Which of the following places would the antenna MOST likely to be located?

Around the laptop's bezel A Wi-Fi antenna performs best when placed in an elevated location. For most laptops, this is around the display within the lid of the laptop. Under the laptop keyboard, next to the laptop battery, and near the memory expansion slots are not likely locations for a Wi-Fi antenna.

The integrated mouse, the small monitor, and the compact nature of the keyboard are impeding your work when you use your notebook, but you still need a system that is portable if necessary. You currently own a spare USB mouse and keyboard, as well as a nice monitor. Which option will give you the portability you need while at the same time save money and not impede your work?

Buy a docking station for your notebook. A docking station lets you use your notebook system as a desktop system. The docking station includes special ports that connect to the back of the notebook and let you use the normal-sized external mouse, keyboard, and monitor you currently own. The docking station provides a quick and easy way to connect these peripheral devices by simply snapping your notebook into the docking station. A lightweight desktop computer is not very portable, as it would require you to bring your external devices (such as the keyboard and mouse) with you as you go from place to place. A big notebook would be portable and would have a larger screen and keyboard but would cost a lot more than a simple docking station. While you may be able to connect your external keyboard, mouse, and monitor manually each time, using the docking station will be more convenient.

You need to replace the video card in a laptop. What is the first step?

Find a service manual with correct disassembly procedures. Before replacing the video card, find the documentation to determine the location of screws and to identify installation sequences for accessing the system components. On most notebooks, you access the video card by removing the keyboard. Some video cards are integrated on the motherboard and cannot be replaced. If the video card can be replaced, you will need to disconnect the display wires. You can typically view or add memory to a laptop by removing the access panel on the bottom of the notebook. The bezel is the case in which the LCD screen is set and typically houses the antenna for wireless network cards.

You have a notebook computer with a built-in wireless network card. One day, it stops working. Because the network card is integrated onto the motherboard, you do not want to replace the entire motherboard. What can you use to connect to the wireless network? (Select TWO.)

Insert a wireless USB network card. Insert an ExpressCard wireless network card. You can add devices to a notebook computer using USB or ExpressCard interfaces. You cannot add a PCI card to a notebook. The infrared port would not be able to connect to the wireless network as it uses a different signal type to communicate between devices. Bluetooth is used to connect to personal area networks (PANs), not LANs.

As an IT technician, you are often asked to work on laptop computers that included internal wireless network cards. Which of the following is the MOST commonly used type of card for these internal wireless adapters?

Mini-PCI Most internal wireless network cards in laptops connect using a mini-PCI interface. USB, Firewire, and ExpressCard are external buses for external devices.

Which type of interface is typically used for internal wireless networking cards in laptops?

Mini-PCI Most internal wireless network cards in laptops connect using a mini-PCI interface. USB, Firewire, and ExpressCard are external buses for external devices.

A user reports that an older laptop is having trouble connecting with newer wireless networks. Which of the following actions should a technician consider as an alternative to replacing the laptop?

Replace the internal wireless card. A newer wireless card may allow the laptop to connect with newer wireless protocols. Additional memory will not affect wireless connectivity. A larger hard drive will not affect wireless connectivity. A new system board using the same wireless card will not affect wireless connectivity.

An internal laptop keyboard is generally connected to the laptop's system board using a:

Ribbon cable A laptop keyboard is generally connected to the system board using a flat, ribbon-like cable. PS/2 ports are used to attach external devices, such as keyboards and mice, to older laptops. USB connectors are used to connect external keyboards to a laptop. The power cable for floppy drives uses a mini-molex connector.

A technician is tasked with replacing an internal laptop hard drive. Which of the following hard drive standards would be of MOST concern when selecting a replacement?

The hard drive's form factor For laptops, the hard drive's form factor is very important. Most laptop's use either the 1.8 inch or 2.5 inch form factor standard. Most hard drives have the same voltage requirements. The storage capacity may drive the cost of a hard drive, but the capacity doesn't usually change whether the hard drive is compatible with a laptop. The read and write speeds may drive the cost of a hard drive, but they don't usually change whether the hard drive is compatible with a laptop.

You're troubleshooting a malfunctioning notebook computer system. The user has indicated that the LCD screen suddenly became dark and difficult to read while he was downloading a large file through his wireless network card while the system was plugged in at his desk. You've checked the system and determined that the backlight has stopped working. Which of the following is the MOST likely cause? (Select TWO).

The inverter in the LCD assembly has malfunctioned. The cold cathode fluorescent lamp has burned out and needs to be replaced. The two main problems encountered with LCD backlights are a burnt out CCFL or a malfunctioning inverter. It's also possible to have a power management setting that turns off the backlight to save power; however, it would only be applied if the system were running on battery. Wireless radio signals do not interfere with the workings of the backlight. Extended downloads does not demand higher DC power. There is no malware that can target backlight circuitry.

After replacing a laptop touchpad, a technician finds that the touchpad does not move the cursor. However, the attached USB mouse does. Before opening the laptop case to re-check the connection, which of the following actions should the technician perform?

Unplug the USB mouse and re-check touchpad movements. If the "Leave touchpad on when a mouse is connected" setting can be cleared, the touchpad may be turned off because the USB mouse is connected. In this case, removing the mouse will activate the touchpad. A minimal boot will not resolve the touchpad issue. Mouse settings don't affect the touchpad's operations. The scroll lock keyboard key doesn't affect the touchpad's operations.

A user normally connects a laptop to a company's network using the laptop's internal wireless NIC. The laptop does not have an Ethernet port. The wireless network has failed, and the replacement part will take two days to arrive. Which of the following solutions will connect the laptop to the company's wired network?

Use a USB-to-RJ45 dongle and connect to a wall jack with an Ethernet cable. A simple solution is to use a USB-to-RJ45 dongle and connect to a wall jack with an Ethernet cable. The USB-to-Wi-Fi dongle would not work because the wireless network is not operating. Although important files could be transferred using a USB flash drive, transferring files does not connect the laptop to the network. A Bluetooth connection may be possible between the laptop and a computer that is connected to the network. However, special software or configurations must be used to pass network traffic from the laptop through the computer and to the network.
