USE DEVICE MANAGER
BJ ECTIVES
The goal of this lab is to help you learn to use Device Manager to compile information on your system's devices and drivers and to uninstall and reinstall a device. After completing this lab, you will be able to: -d Use Device Manager to investigate your system specifications "$ Compile additional information for your Computer Inventory and Maintenance form
.x Uninstall and reinstall a device
MATERIALS REQUIRED This lab requires the following: .d lTindows 7 operating system
j
Computer Inventory and Maintenance form you used in Chapter
1
LAB PREPARATION Before the lab begins, the instructor or lab assistant needs to do the following:
*
Verify that'Windows starts with no errors
ACTIVITY BACKGROUND Device Manager is an excellent tool for finding information about hardware specifications. As you continue to work with different kinds of computers, you'll find it extremely useful to maintain a report listing the components installed on each computer. This report is especially important if you're responsible for many computers. In this lab, you record additional information on the Computer Inventory and Maintenance form that you started in Chapter 1,. (Note that you might want to refer to this document in future labs as well.)
When a device is giving a problem, one thing you can do is to uninstall and reinstall the device. Suppose, for example, you cannot connect a computer to the network. After verifying network physical connections, Windows network settings, and Device Manager for reported errors, you consider that the network adapter drivers might be corrupted. You can eliminate the drivers as the source of the problem by uninstalling and reinstalling the device. 'When you first install a device, Windows stores a backup copy of the device drivers in a driver store. Later, if you uninstall and reinstall the device, it uses the drivers in the driver store rather than requesting that you provide the drivers again. This can be a convenience but can also present a problem if the driver store is corrupted. To thoroughly eliminate the

drivers as the source of a problem, take time to delete the driver store when you uninstall the drivers. Then you must provide a fresh copy of the device drivers when you reinstall the device.
In this lab, you get practice using Device Manager to manage device drivers.

189
ACTIVITY BACKGROUND Two of the most popular multimedia devices are the sound card and the embedded audio device. A sound card enables a computer to receive sound input and to output sound, such as when playing a music CD. Many newer systems have audio embedded on the motherboard' As a computer technician, you need to know how to install a sound card, whether you're putting together a computer from scratch, repairing a fatled device, or upgrading components on an existing system. In this lab, you install, configure, and test a sound card.
'T,activi-tg First, you need to find out whether your system has a sound card, an embedded audio device, or perhaps both or neither. Use the skills you have learned to discover and describe what audio configuration your system currently has. Describe the configuration and then work through the steps to complete the lab in the following general order:
.* Disable any existing audio
devices in Windows.
.d Remove or disable the hardware device(s)'
x Verify that the audio is disabled. s Physically install a sound card. x Install the drivers in'Windows. "* Verify the function of audio features. .d.6 Return the system to its original state (optional, per your instructor's directions). Follow these steps to uninstall a sound card or embedded audio device in Windows: 1. After you have logged on as an administrator, open Control Panel.
2. Click System and Security, and under System, click Device Manager. 3. Expand Sound, video and game controllers and select your audio device. 4. Right-click your device and click Uninstall. 5. If necessary, check the Delete the driver software for this device box, as shown in Figure 8-3, and click OK.
6. Close any open windows' log off' and shut down your computer. Next, you will either physically remove the sound card from your system or disable an audio
device
that's embedded in the motherboard. Follow these steps to remove a sound card:
1. Disconnect all external cables and cords from the case. Press and hold the power button for three seconds to drain any remaining power in your computer. 2. Using all safety precautions, including an antistatic wrist strap, remove the case cover and locate the sound card. Describe any cables connected to the sound card and the ports they are connected to:

3. Disconnect any cables from the sound card. Remove the sound card and place it in
a
safe place.
4. Reassemble the computer without the sound card and boot to l7indows to verify that the audio isn't functioning.
A motherboard might have onboard (embedded) audio ports or headers. If so, we want to disable these audio devices. For most computers, this is done using the BIOS setup utility. Older computers used jumpers on the motherboard to enable or disable onboard audio. Follow these steps to disable the embedded audio device: 1. Examine the motherboard ports. Does the motherboard have onboard audio ports?
2. Consult the motherboard documentation to learn how to disable any embedded audio devices. How is onboard audio enabled and disabled?
3. If your motherboard
has onboard audio that is disabled using BIOS setup, enter BIOS setup and disable the embedded audio device. Describe the steps you took:
If your motherboard has onboard audio that is disabled using jumpers, follow these steps: 1. Disconnect all external cables. Press and hold the power button for three seconds to drain any remaining power.

3. Remove any internal audio cables. 4. Reassemble the system and boot to Windows to verify that the audio isn't functioning. Now you are ready to physically install a new sound card. Follow these steps: 1. Shut down the computer and disconnect all external cables from the case. Press and hold the power button for three seconds to drain any remaining power. 2. Using all safety precautions, including an antistatic wrist strap, remove the case cover. 3. Locate an empty expansion slot that you can use for the sound card. On some systems, expansion cards are attached to a riser card, which you might have to remove at this time. If necessary, remove the expansion slot faceplate on the case so that the sound card fits into the expansion slot. Some systems will use a screw to hold a slot faceplate in place, while others will use a clip or passive restraint system to hold the faceplate in place. 4. Insert the sound card into the expansion slot on the motherboard (or insert the sound card into the riser card and the riser card into the motherboard). Line up the sound card on rhe slot and press it straight down, making sure the tab on the backplate (the metal plate on the rear of the card where sound ports are located) fits into the slot on the case. Normally, seating the card requires a little effort, but don't force it. If you can't insert the card with just a little effort, something is preventing it from seating. Check for obstructions and try again, removing components that are in the way, if needed. After you have inserted the sound card, verify that the gold "fingers" on the sound card are even across the length of the slot or that no gold is showing. secure it to the case with a screw or the passive restraint flange. The screw goes through a hole in the card's backplate, securing the backplate to

6. Attach all cables required to carry an audio signal from other multimedia devices, such as a CD-ROM drive. 7. Replace any components you removed while installing the sound card, and replace and secure the cover on the case.
8. Reattach all cables from external devices to the correct ports. Attach speakers or headphones. (Some speakers receive power from the computer, and others have to be plugged into an external power source) such as a wall outlet.) Next, you configure the drivers and other software for your sound card. If you have the documentation for your sound card, follow those instructions. Otherwise, follow these general steps to install software for most sound cards, keeping in mind that your sound card might require a slightly different procedure:
1. Start the computer, and log on as an administrator. If an "Installing device driver software" balloon pops up, you can wait for the drivers to install.
x If the installing device driver balloon has popped up, what does the system recognize this device
as?

Is this the full name of the sound card you are installing? If not, why?
2. If the drivers do not automatically install, insert the CD containing the drivers. !7hen the AutoPlay window appears, click Run setup.exe.
3. The next window that appears most likely asks about install options, including installing drivers and installing additional software for supporting the sound card's functionality. For our purposes we are just installing the device drivers. Select that oPtion.
4. Follow the screen prompts to complete the install. At the end of the process the software might ask to reboot the system. Follow these steps to test the sound card and adjust the volume in lTindows: 1. Open Control Panel. Click Hardware and Sound and then click Sound. The Sound dialog box opens, as shown in Figure 8-4.

ACTIVITY BACKGROUND Having two displays on a system is often quite handy. For instance, two monitors give you more desktop space and make it easier to work with multiple applications simultaneously. You might keep tabs on your e-mail on one screen while surfing the Internet on the other. Alternatively, your second display could be something else, like an LCD display for presentations or a television for watching movies. In this lab, you install and configure a second display on a computer.
@ activity It's important to verify that the original hardware is working correctly before you try to add a second display adapter and monitor. That way, if a problem comes up after you install new hardware' you can be fairly sure something is wrong with the newly added components rather than the original equipment. Also, you should make sure the hardware is on the lTindows Hardware Compatibility List (HCL) or, at the very least, the device manufacturer offers drivers and specific instructions for use with your version of Windows. There are two options to attach a second monitor. One option is to install a second video adapter and second option is to use a dual-ported video adapter.
a
INSTALL A SECOND VIDEO ADAPTER Follow these steps to physically install the second display adapter: You can borrow a video adapter from another computer
if
in the lab and wotk with a partner,
needed.
1. Check to see if the original video adapter uses a PCI, AGP, or PCIe standard, and decide whether it will be the primary or secondary display. ",* What is the standard of the original video adapter?
,,,;
lJ7ill the monitor artached to the original adapter be the primary or secondary display?
2. Determine which standard the new video card follows (PCI or PCIe) and install the
second
adapter card in the closest available slot to the original video card.
j
\i7hat is the standard of the new video adapter?
If you need additionat guidance on instatling an I/O card, use a pro€ess simitar to instatling the sound card in Lab 8.3.
3. Attach the second display to the port on the back of the display adapter. 4. Boot your computer and enter BIOS setup. If your setup has display settings for dual monitors, adjust them so that the card you've chosen as your primary display adapter is
initialized first.

5. If your system has an AGP adapter, make sure that it is selected
I

as the primary adapter
and the PCI adapter as the secondary adapter. For a system that uses two PCIe adapters, it doesn't matter which adapter is the primary one; you can leave the setting as is. For additional guidance on adjusting BIOS settings, refer to Lab 4.2.
6. If you don't see this setting, your BIOS doesn't support this option, so exit BIOS setup and wait for your system to finish booting. .Windows display settings: Follow these steps to install device drivers and adjust '$fhen 1. the system boots, log on as an administrator. $Tindows recognizes the new adapter and displays a Driver Software Installation icon in the taskbar's notification area. Above the icon, a balloon tip appears with a notification about the driver installation.
2. At this point, S7indows might install the drivers automatically for you (if the drivers were available when your version of Windows was published) or launch the Found New '$Tizard if the adapter is new enough that l7indows isn't aware of the correct Hardware drivers. Complete the steps in the wizard to install the adapter. S7hen the installation is completed, shut down the system. Plug the second monitor into the video port on the second video card. USE
A DUAL-PORTED VIDEO
ADAPTER
Follow these steps to install a second monitor on a dual-ported video adapter.
1. Locate the port(s) on the video adapter. You will be able to either attach a monitor cable to each port or a splitter adapter for two monitors. Attach the appropriate cable. Be aware of the appropriate port interfaces and have the correct adapter. 2. PIug each monitor into the video card and turn the monitors on. USE A SECOND MONITOR Before you use a second display, you must activate it. To do so, follow these steps:
1. Boot your computer and you will see both screens have a loading'S7indows display and then one of the monitors goes black. 2. If necessary, log on as an administrator. Upon reaching the desktop, the second monitor may activate. If it doesn't, you will need to change a setting. 3. Open Control Panel, click Appearance and Personalization, then click Display. Click Adlust resolution to open the Screen Resolution window. 4. The area at the top of the Screen Resolution window now displays two monitors. Click the ldentify button to determine how the system is labeling your new monitor. As a result, click the image of the monitor that is your new monitor.
5. Adjust the resolution to your preference by clicking the down arrow on the Resolution drop-down box.
6. Click the down arrow on the Multiple displays drop-down box and then click Extend these displays.
7. Click Apply to apply the settings. The second monitor displays the desktop. 8. There is a shortcut to get to this Screen Resolution window.'$frite down the access the Screen Resolution window quickly:

3. Shut down the computer. Don't restart the computer at this time. 4. Remove the second display and adapter card. If necessary, reverse any BIOS changes you made that affect the display initialization sequence, and reboot the system to verify that the system no longer recognizes the adapter card. Follow these steps if using a dual-ported video adapter:
1. Shut down your computer system. 2. Remove the second video cable to return the video adapter card to single monitor
setup.
