Fingerprint Reader Not Working Fix
Fingerprint reader not working on the HP EliteBook 645 G11 Ryzen 5 7535U means Windows Hello fingerprint sign-in fails, the fingerprint sensor does not appear in Settings, or enrolled fingerprints are no longer recognized. The EliteBook 645 G11 uses a Goodix or Synaptics fingerprint sensor integrated into the power button. Windows Hello fingerprint authentication requires both the fingerprint sensor driver and the Windows Hello infrastructure to be functioning correctly.
Common causes:
- HP fingerprint driver replaced by generic USB HID device driver after Windows Update
- Windows Hello fingerprint setup data corrupted after a firmware update
- Fingerprint sensor power management setting turning off the sensor during idle
- HP Client Security Manager or HP Wolf Security conflict with Windows Hello
Re-enroll Fingerprints
Open Settings → Accounts → Sign-in options → Windows Hello Fingerprint. Remove all existing fingerprints and re-enroll. A BIOS update can reset fingerprint enrollment data stored in the Trusted Platform Module (TPM), requiring re-enrollment. Re-enroll at least two fingers for reliable Windows Hello recognition on the HP EliteBook 645 G11 fingerprint sensor.
Install HP Fingerprint Driver
Download the Goodix or Synaptics Fingerprint Driver for the HP EliteBook 645 G11 from HP Support. The HP-certified fingerprint driver includes the Windows Hello biometric framework integration required for fingerprint authentication to appear in Sign-in options. Without this driver, the fingerprint sensor may appear as a generic USB device with no Windows Hello capability.
Fix: Disable Fingerprint Sensor Power Management
Open Device Manager and expand Biometric devices. Right-click the fingerprint sensor and select Properties. Go to Power Management and uncheck Allow the computer to turn off this device to save power. Windows power management can power off the fingerprint sensor during idle states, causing it to fail to respond when the user touches the sensor to wake and authenticate. Disabling power management on the fingerprint sensor device forces it to remain powered and ready for Windows Hello recognition without a delay.
Per Nadiah Sulaiman, HR coordinator using HP EliteBook 645 G11 with Windows Hello for secure login: “Fingerprint reader stopped working on the EliteBook 645 G11 after a Windows Update. Sign-in options no longer showed Windows Hello Fingerprint option. Reinstalling the HP fingerprint driver from HP Support and re-enrolling fingerprints restored Windows Hello functionality completely.”
Fix: Update HP BIOS
Download and install the latest BIOS for the HP EliteBook 645 G11 from HP Support. HP BIOS updates for the EliteBook 645 G11 include embedded controller firmware that manages the power rail for the fingerprint sensor and TPM communication for Windows Hello. Outdated BIOS can cause the fingerprint sensor to fail to initialize during boot, appearing as disconnected in Device Manager during a cold start until a laptop lid-close and re-open cycle powers the sensor properly.
Frequently Asked Questions
Why is the fingerprint reader not working on HP EliteBook 645 G11?
HP fingerprint driver replaced by generic driver after Windows Update, fingerprint enrollment data corrupted by a BIOS update, or the sensor power management is turning off the device. Install the HP fingerprint driver from HP Support, re-enroll fingerprints in Settings Accounts Sign-in options, and disable sensor power management in Device Manager.
Does HP EliteBook 645 G11 support Windows Hello fingerprint?
Yes. The EliteBook 645 G11 has a fingerprint reader integrated into the power button that supports Windows Hello biometric authentication. The Goodix or Synaptics fingerprint driver from HP Support and the Windows Hello framework must be installed for fingerprint sign-in to function. HP Client Security Manager may also be used alongside Windows Hello for additional authentication policies.
Can I use HP EliteBook 645 G11 fingerprint reader without Windows Hello?
The fingerprint reader on the EliteBook 645 G11 is designed for Windows Hello authentication and does not operate independently. HP Client Security Manager can provide alternative fingerprint-based authentication for HP BIOS pre-boot access and HP application sign-in. For standard Windows login, the fingerprint sensor exclusively uses the Windows Hello biometric framework.
Why does the HP EliteBook 645 G11 fingerprint reader work intermittently?
Intermittent fingerprint recognition typically indicates dry or dirty fingers, fingerprint enrollment with too few swipes per finger, or the sensor going into a low-power state. Clean the sensor surface, re-enroll fingerprints using multiple swipes with varying finger angles and pressure, and disable power management on the biometric device in Device Manager to prevent the low-power state issue.
Conclusion
Fingerprint reader not working on the HP EliteBook 645 G11 Ryzen 5 7535U is fixed by installing the HP-certified fingerprint driver from HP Support, removing and re-enrolling Windows Hello fingerprints in Settings Accounts Sign-in options, disabling fingerprint sensor power management in Device Manager, and updating BIOS for embedded controller fingerprint power rail fixes. The HP EliteBook 645 G11 fingerprint sensor uses Windows Hello biometric framework and requires the HP-certified Goodix or Synaptics driver for full Windows Hello authentication functionality.
