Mobile Computers and Power Management
1. You have a portable computer that you've upgraded to Windows XP Professional from Windows 98. You notice that the computer no longer powers down when you execute the Shutdown command. What must you enable with the Power Options control panel in order to fix this problem? (Choose the best answer.)
C. A power scheme
2. You have a portable computer that runs Windows XP Professional. You spend about half your time at the office and half your time on the road, so your manager authorizes a docking station, which you get a good deal on because it's been discontinued by the manufacturer. You set up a second hardware profile so that Windows XP can take advantage of the docking station's network card and high-res display adapter.
You reboot the computer, go for a cup of coffee, and come back to find that your docked computer doesn't seem to be using the network card. You check the maximum resolution of the display, and the computer isn't using the high-res video card, either. What setting should you change in order to fix this problem? (Choose the best answer.)
A. Wait until I select a hardware profile, on the Hardware Profiles property sheet
B. Select the first hardware profile listed, on the Hardware Profiles property sheet
C. Profile= , in the BOOT.INI file
D. StartupProfile, in the Registry
3. You're traveling on a transatlantic flight and need to conserve battery power for your ACPI Windows XP Professional notebook computer. When you get ready to take a nap after the delectable airline meal, what state should you put your notebook computer into in order to minimize the likelihood of lost data? (Choose the best answer.)
A. Perform a normal shutdown that powers your PC off.
B. Initiate Standby mode.
C. Initiate Hibernate mode.
D. Initiate ACPI mode.
4. You're a traveling salesperson with a Windows XP Professional notebook computer. While on the road, it's very important for you to be in touch with the home office. So, you travel with two modems, just in case one breaks. Both use the PC Card bus. You install the first one with Plug and Play, and it tests out fine; the installation script puts the modem on COM1. Then you install the second modem into your second PC Card slot. It seems to install fine, but when you try to use it, you get an error message that says 'Unable to open port.'
Clearly, the two devices aren't happily coexisting on this computer, probably because both are wanting to use COM1. What should you do to correct the problem? (Choose all that apply.)
A. Create two hardware profiles. Uninstall one modem in each profile.
B. Create two hardware profiles. Disable one modem in each profile.
C. Use Device Manager to disable one of the modems.
D. Use Device Manager to uninstall one of the modems.
E. Use Phone and Modem Options to disable one of the modems.
F. Use Phone and Modem Options to uninstall one of the modems.
5. Jim is a member of the Power Users group. He gets a new PC Card network adapter for his notebook computer. During the installation, Plug and Play asks Jim for the location of the appropriate driver for the network adapter. He provides that information, but the driver installation fails. What should Jim do? (Choose the best answer.)
A. Run the Add/Remove Hardware Wizard instead of using Plug and Play.
B. Run the Scan New Hardware command in Device Manager.
C. Log on as Administrator and try again.
D. Obtain another copy of the driver media.
6. You want to retrofit an infrared data port to your Windows XP Professional computer. You evaluate various models and review their spec sheets. Which of the following is the most attractive specification? (Choose the best answer.)
7. You're installing a PC Card modem into a Windows XP notebook and you can't get the modem driver to install. What should you try? (Choose the best answer.)
A. Boot to Safe Mode.
B. Install a COM port.
C. Install the generic PC Card minidriver.
D. Disable Plug and Play.
E. Log on as a Power User.
8. You're configuring a notebook computer for Standby mode. You want to set the machine so that it prompts for a user name and password when it comes out of Standby. Where do you make this setting? (Choose the best answer.)
A. Power Options, Advanced tab
B. Power Options, Standby tab
C. Power Options, Power Schemes tab
D. Local Security Policy console
1. A. APM version 1.2 is supported for Windows XP Professional running on older computers, but it isn't enabled by default if Windows Setup doesn't recognize the specific APM BIOS as being one that's supported. Activate APM on the APM tab of the Power Options control panel. You can't enable or disable ACPI; if Windows XP detects that a machine is ACPI-capable, Windows uses ACPI features automatically. Review 'APM.'
2. A. What happened, most likely, is that when you rebooted the PC and left for a caffeine infusion, Windows waited the default number of seconds and chose the first hardware profile in the list, which specifies the undocked configuration. In that case, Windows may not autodetect the hardware in the docking station, especially considering that the station is a bit outdated. Your best bet would be to tell Windows to always wait and let you decide which profile you want at boot time. Choice B isn't flagrantly wrong, but if you spend half your time at the office (docked) and half on the road (undocked), you don't have a clear choice. Review 'Hardware Profiles.'
