Fingerprint not working after the laptop turn the display off

[Rasyidm]

Hi, so my laptop (HP envy X360 Ar series with ryzen 7) fingerprint often not working after the screen turned off after i letting it idle. I also encountered "fingerprint cannot detect, please clean the fingerprint sensor" while i dont touch the sensor. i have tried reinstalling the driver, reset windows 10, cleaning the fingerprint sensor but nothing works. How do i fix it ? anyway i'm currently using Windows 10 1903 build and the driver is downloaded from hp support page. Thanks

Edit: my laptop also turned off suddenly while i was browsing, idk what caused it.

bios version : f.16

Thank you for posting on the HP Support Community.

• Did this happen after a recent window or software update?
• Have you tried updating the BIOS?

While you respond to that, let's try these steps: 
Let's check your BIOS for biometric support and enable it:

1. Press the Power button to start the computer, and press the F10 key to open the BIOS setup utility.

2. Under System Configuration, look for a Biometric Device option; if it exists, enable it.

3. Press F10 to save this setting and restart the computer.

If a biometric option does not exist in your BIOS, then the fingerprint reader is always enabled. 

Hope this helps! Keep me posted for further assistance.

Hi,

1. No, it happens a few months back (about 1 or 2 months) before updating everything

2. yes, i use the latest bios (F.16 Rev A)

there's no option for biometric device option.

No, it's still not working after entering standby mode (when the screen turned off)

That's unfortunate. Let us try these steps to resolve this issue:

On the PC, go to Device manager > Expand Biometrics > Right-click on the Synaptic sensors > Uninstall

Reboot the PC to automatically reinstall the driver.

Check if the issue persists.

Check your BIOS for biometric support and enable it:

1. Press the Power button to start the computer, and press the F10 key to open the BIOS setup utility.

2. Under System Configuration, look for a Biometric Device option; if it exists, enable it.

3. Press F10 to save this setting and restart the computer.

If a biometric option does not exist in your BIOS, then the fingerprint reader is always enabled.

Go to the Software and drivers page in HP Support site for your PC and check for HP Simple pass, download and install if available.

Let me know how this goes.
