Device feature not working
4.5
A specific hardware feature (like a fingerprint reader, webcam, or touch screen) is unresponsive.
Symptoms
- Feature doesn't respond to touch/input
- Missing from settings
- Error code in Device Manager
Possible Causes
- Missing driver
- Hardware failure
- Disabled in BIOS
Step-by-Step Fix
1
Check Device Manager
Look for any "Unknown Device" or items with a yellow exclamation mark.
2
Update Firmware
Download the latest BIOS/UEFI update from the manufacturer's support page.
3
Test in Safe Mode
If the feature works in Safe Mode, a third-party app is blocking it.
When to See a Technician
If a feature stops working after a physical drop, an internal ribbon cable may have come loose.
