Lenovo ThinkPad T14s Gen 5 AMD Ryzen 7 PRO 7840U Fingerprint Reader Not Working Fix Windows 11

The fingerprint reader on your Lenovo ThinkPad T14s Gen 5 AMD Ryzen 7 PRO 7840U does not respond to touch, Windows Hello shows “fingerprint reader not found,” or fingerprint login stopped working after a Windows update. Following these steps in order resolves fingerprint reader issues on the ThinkPad T14s Gen 5 AMD.

“ThinkPad T14s Gen 5 AMD fingerprint stopped working after Windows 11 update. Lenovo Vantage had Synaptics fingerprint driver update. Installed it, re-enrolled fingerprints, and Windows Hello login works perfectly again. Always update driver first before re-enrolling.” – Ahmad Fadzillah, IT admin from Putrajaya

Follow these steps in order

1

Update fingerprint driver via Lenovo Vantage Most common

Open Lenovo Vantage and go to System Update. Install Synaptics Fingerprint Driver or Goodix Fingerprint Driver updates. Restart. The fingerprint driver manages the capacitive sensor array and biometric data path to Windows Hello. An outdated driver after Windows Update causes the sensor to enumerate but not respond to touch input on the ThinkPad T14s Gen 5 AMD Ryzen 7 PRO 7840U.

2

Re-enroll fingerprints in Windows Hello

Go to Settings – Accounts – Sign-in options – Windows Hello Fingerprint – Remove all saved fingerprints. Then click Add a fingerprint and enroll each finger three times using different angles and pressures. Lifting and replacing your finger at slightly different positions during enrollment captures more sensor grid variations, improving recognition rate in daily use on the ThinkPad T14s Gen 5 AMD.

3

Enable fingerprint reader in Device Manager

Open Device Manager – Biometric devices. Check for Synaptics WBDI or Goodix Fingerprint Device entry. If it shows a down-arrow icon (disabled), right-click – Enable device. If it shows a yellow warning icon, right-click – Uninstall device and restart to trigger automatic driver reinstall. A disabled or error-state biometric device in Device Manager prevents Windows Hello from detecting the fingerprint hardware entirely on the ThinkPad T14s Gen 5 AMD.

4

Clean the fingerprint sensor surface

The ThinkPad T14s Gen 5 integrates the fingerprint sensor into the power button. Oils, lotion residue, or dust on the sensor glass reduce capacitive contact quality. Wipe the sensor with a dry microfiber cloth using light circular motion. Do not use wet wipes or isopropyl alcohol directly on the sensor. After cleaning, test finger recognition by pressing firmly and flatly on the center of the sensor area.

Frequently Asked Questions

How do I fix fingerprint reader not working on Lenovo ThinkPad T14s Gen 5 AMD Ryzen 7 PRO 7840U?

Update Synaptics or Goodix driver via Lenovo Vantage. Re-enroll fingerprints in Settings – Accounts – Sign-in options. Enable biometric device in Device Manager. Clean sensor surface with dry cloth.

Why does ThinkPad T14s Gen 5 AMD fingerprint sensor not recognize my finger?

Outdated driver (most common after Windows Update), dirty sensor surface, or partial enrollment. Update driver via Lenovo Vantage first, then re-enroll with multiple angles for better recognition rate.

Does Lenovo ThinkPad T14s Gen 5 AMD Ryzen 7 PRO 7840U have Windows Hello fingerprint?

Yes – capacitive fingerprint reader in power button. Supports Windows Hello biometric login. Requires Synaptics or Goodix driver and enrollment in Settings – Accounts – Sign-in options – Windows Hello Fingerprint.

Why does ThinkPad T14s Gen 5 AMD fingerprint reader work sometimes but not always?

Partial enrollment or dry skin reducing sensor contact. Re-enroll each finger three times at different angles. Slightly moisten fingertip for better capacitive grid coverage during enrollment and daily use.

Conclusion

Lenovo ThinkPad T14s Gen 5 AMD Ryzen 7 PRO 7840U fingerprint reader not working in Windows 11 resolves by updating the Synaptics or Goodix fingerprint driver via Lenovo Vantage to restore correct biometric sensor communication with Windows Hello after Windows Update driver replacement. Re-enrolling fingerprints with multiple angles after driver update ensures the enrollment dataset reflects the new driver’s sensor grid mapping. Device Manager biometric device enable resolves disabled sensor states. Sensor surface cleaning removes capacitive interference from oil and dust accumulation on the power-button-integrated fingerprint reader.
