You are the desktop administrator for your company. You install Windows XP Professional on your portable computer. The computer is configured to use an IEEE 1394 PC card. You use the computer to download pictures from a digital camera while you are at the office. You attend a meeting every Monday. During the meeting you use a battery to supply power to your portable computer. Occasionally, the battery runs out of power during these meetings. You need to configure the computer to conserve battery power while you attend your weekly meeting without affecting your power options when you use the computer at your office. How should you configure your computer?
A.
Use Device Manager to disable the IEEE 1394 PC card power device.
B.
In Control Panel, select the Minimal Power Management power scheme in the Power Options Properties.
C.
Create an additional hardware profile, and disable the IEEE 1394 PC card for this profile.
D.
Use Device Manager to configure the IEEE 1394 PC card Host Controller power management scheme. Select the Allow this device to bring the computer out of standby check box.
Explanation:
To ensure the optimal performance in different networking environments, we should create different hardware profiles that the users can choose from under different network environments. We do not require the IEEE 1394 PC card at the meeting therefore we should create a profile that has the IEEE 1394 PC card disabled to save the battery resources used to power this card. We can then choose this profile when we are at the meeting.
Incorrect Answers:
A. Using Device Manager to disable the IEEE 1394 PC card would disable the device in the current profile. We should create a new profile by copying the current profile, provide a name for the copied profile and select the new profile when we reboot the computer. We can then disable the device in the new profile and will be able to select the new profile when we boot the computer at the meetings.
B. In the Minimal Power Management power scheme, some power management features, such as timed hibernation or a timed event that can put the disk drive in a sleep mode, are disabled. This will thus conserve less battery power than the default power scheme, which is the Always On power scheme.
D. Configuring a device to bring a computer out of standby mode will not decrease the device’s power consumption. It will only configure the device to bring the computer out of standby mode when activity is detected in the device.
