Show answer and explanation
Correct answer: C
Explanation
When Device Manager shows a yellow triangle with an exclamation mark, it indicates a driver or configuration issue with the device. Uninstalling the device and reconnecting it forces Windows to reinstall the driver automatically, often resolving conflicts or corruption. This step is generally preferred before assuming hardware failure or attempting other actions like disabling the device.
- A. Incorrect.
Selecting 'Update driver' may help if the issue is related to an outdated driver, but it does not address potential corruption or misconfiguration of the existing driver.
- B. Incorrect.
Disabling the device and restarting the computer will not resolve the issue, as the device needs to be reinstalled or updated to function correctly.
- C. Correct.
Uninstalling the device and reconnecting the keyboard forces the system to reinstall the driver, which is a common troubleshooting step for resolving hardware conflicts or corrupted drivers.
- D. Incorrect.
Ignoring the warning could result in overlooking a driver or configuration issue, and assuming the hardware is defective without further investigation is not a reliable troubleshooting approach.
