Jane is trying to connect a flash drive to her friend’s desktop computer. The drive doesn’t seem to work in any of the USB ports. However, the drive works on her laptop. Which of the following could be the most likely cause of the issue?
  1. The drive works only on laptop computers
  2. The processor is faulty
  3. The drive is faulty
  4. USB is turned off in the desktop BIOS
Explanation
Answer - D - Since the drive is working on the laptop computer, it can be inferred that the flash drive works fine. Most of the time, a good flash drive does not work on a computer because the USB option will be turned OFF in the CMOS setup. Another cause for a flash drive to not work could be faulty USB ports on the desktop computer. Verify the integrity of the ports by connecting good-known USB devices to these ports.

Key Takeaway: The sequence of steps to follow when a USB drive does not work on a USB port is:

1. Try using the drive in any other port. If it works on any one of the slots, that means the other slots are faulty.
2. Try using another good-known drive on these ports.
3. Check if the USB option is turned ON in the CMOS setup.
