I can give you some places to check and some things to try.




If the fingerprint reader is still in the Device Manager > Biometric Devices

Uninstall it - Restart the computer and let it reinstall the driver


HP Updates

As a check, make sure your HP Software and Drivers are current and installed.

Open your SDM software and Check for Updates.

If you do install any software / updates, Restart the computer and log in (regardless of whether the "restart" is required).


Security Software

This is likely not the problem; it only takes a few keystrokes to check...

Make sure your HP Client Security software is working.

You do NOT need to have anything like the SpareKey set up - you do want to check the Dashboard and make sure the settings are still working for the fingerprint login (finger prints are enrolled).  


Example - Client Security - Fingerprint setup



Silly PIN may be stuck - PIN is required for Fingerprint login

In Windows Settings > Sign-in Options, consider removing and re-adding the PIN.



Clear the boot memory - boot computer from a full stop condition

Although it should not be necessary, it is possible that something in the boot (especially if you use Fast Boot) is stuck.  (Personally, I never use Fast Boot anymore - Zbook boot is fast enough.  Smiling.)


Clear the previous boot instructions from the memory and force the computer to read the operating system as installed on the disk.  NOTE:  This process does NOT harm a healthy system.


  1. Unplug everything, including power and all other externally connected components
  2. Press and hold down the power button for thirty (30) to forty (40) seconds
  3. Release the power button
  4. Plug in only basic components needed to start / boot the computer


  • Desktop:  Connect Power, wired mouse and keyboard, HDMI to monitor (and monitor is powered on)
  • Notebook:  Connect AC Power


  1. Switch on the system with power button - Click power and release (as for normal boot)


Check...Everything OK (system boots)?  Plug in your peripherals (if any) and continue on with life.



For those reading...reference

Switch off / on Fast Start / Fast Boot


Settings   > System > Power and Sleep > Additional Power Settings >

Choose what the power button does >

Click Change settings that are currently unavailable >

Remove Check (clear box) Turn on fast startup (recommended) >



  • Close programs (browsers, games, email, etc) and close any open windows


Windows key + X (opens a command list) > Click / Select Command Prompt (Admin) >

When the command window opens, type the following command and hit Enter:

shutdown /s /t 0


  • Wait for the computer to shut down completely (a few seconds)
  • Boot the computer > Log in > Wait around for a couple of minutes (yes, wait, do not rush) >
  • Try shutting down the notebook from Windows key > Power


If all now works as expected, and you want to continue using Fast Boot,

Switch ON the fast boot / fast startup setting (optional)

Not sure...

It is possible, though unlikely, that the fingerprint reader has failed. 


You might want to boot into the BIOS to make sure that the device is not in some way disabled (unlikely to be the case). 

Optional:  If you like, set the BIOS back to "Default".


One of many references available...

Restoring the BIOS Default Settings



If the first step in original post (simple uninstall driver from Biometrics) and Restart did not work for any reason, the Device Manager won't be able to detect the fingerprint reader.


Try / Consider:


Download and save your Biometrics Driver to your computer

Synaptics WBF Fingerprint Driver


Control Panel > view icons > Device Manager
Open Biometrics > Right-Click on device
Properties > tab Driver
Uninstall Device >
Check Box
"Delete the driver software for this device"


Restart the computer and log in



Open File Explorer

Navigate to the folder in which you saved the driver installation package (likely Downloads)

  • If you have ‘Admin’ control, you may highlight the package and “double-click” to install it, else Right-Click, select run as Administratorand install.


Restart the computer and log in.


If I think of anything else to add, I will post back.
