A user is having difficulty logging into their laptop using the fingerprint reader. They have correctly registered their fingerprint, but the device still fails to recognize it. As an IT technician, what is the FIRST action you should take to troubleshoot this issue?
Reset all system settings to factory defaults.
Clean the fingerprint reader to ensure it is free from dust, oils, and residue.
Update the driver for the fingerprint reader.
Check for physical damage to the fingerprint sensor.
Cleaning the fingerprint reader is the first step in troubleshooting the device as oils and residue from fingers can often interfere with the sensor’s ability to accurately detect fingerprints. Updating the driver or resetting the device settings should only be considered after ensuring the fingerprint reader is clean, as these are more complex steps that may not be necessary. Checking for physical damage to the sensor would be part of a visual inspection and could be done in conjunction with cleaning.
