1. A. Verify the output voltages from the power supply unit.
2. B. Open the computer cabinet and replace the power button.
3. C. Remove and reconnect all cables that are plugged into the motherboard
4. D. Reseat the power cable and confirm the outlet is providing energy.

Correct Answer: D
The first step in troubleshooting a computer that does not turn on when the power button is pressed is to check if there is any power going to the computer. The technician should reseat or reconnect the power cable to ensure it is firmly attached to both ends, and confirm that the outlet or power strip is providing energy by using a multimeter or another device. This can eliminate any issues with loose or faulty connections or power sources, and help isolate the problem further.

An integrated webcam on a user's laptop broke, so a technician installed a temporary, external webcam. Since the external webcam installation, other users can only see part of the user's face during videoconferences. Which of the following BEST describes the reason for this issue?

1. A. The webcam is not on a level surface.
2. B. The webcam driver should be updated.
3. C. The webcam is plugged into the wrong USB port.
4. D. The webcam is not compatible with the OS.

Correct Answer: A
The most likely reason for the issue is that the webcam is not on a level surface, which causes the camera angle to be distorted. The user should adjust the position of the webcam so that it is aligned with the laptop screen and captures the user’s face fully. The other options are not relevant to this issue, as they would not affect the camera angle or visibility of the user’s face. Verified References: How to Position Your Webcam Correctly.

Vertical streaks are appearing on the output of a laser printer. Which of the following items is the MOST likely cause?

1. A. Roller
2. B. Drum
3. C. Transfer belt
4. D. Ribbon

Correct Answer: B
Vertical or horizontal lines—Marks that appear in the same place (referred to as repetitive defects) are often due to dirty feed rollers (note that there are rollers in the toner cartridge and fuser unit too) or a damaged or dirty photosensitive drum.
Vertical streaks on a laser printer output are usually caused by a damaged or worn-out drum, which is responsible for transferring toner to the paper. If the drum is damaged, toner may accumulate on certain parts of the drum, leading to streaks on the printed output.
