hp elitebook 840 g1 fingerpint does nog work when starting Windows 10 pro

[AnneKrist]

Elitebook 840 G1 Fingeprint scanner does nog work on login Windows. It works when adding a fingerprint but at login windows it doesnt react to my finger. Not even a malfunction message.

It worked fine for years but all of a sudden it stopped working. The bios sollution does not help and now the possibility to login using fingeprint scanner has dissapeared.

If have several hp elitebooks but only this one has a problem. Looks like a windows update problem.

Been using these elitebooks for years now and this is the first problem i have with one. For te rest they are great.

first of all Create a Restore Point in Windows

(2) Check the FAT (file allocation table) of your system drive for errors and incorrect entries:

open an cmd.exe shell as administrator the execute the following commands and prepare a coffee ...

----------------------------------------

( note: confirm the question(s) with Y = Yes)

chkdsk /f c:
shutdown /r /t 0

( your operating system will be rebooted, take a coffee and wait for the check to be completed on the next startup, don't interrupt the process.

Several reboots may occur )

----------------------------------------

(3) Then open an cmd.exe shell as administrator the execute the following commands and prepare a coffee ...

----------------------------------------

Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth
Dism.exe /Online /Cleanup-Image /StartComponentCleanup
SFC /scannow

shutdown /r /t 0

thank you for helping me. This is why i am a fan of hp. The bios update process takes a lot of time. after restarting i will try your suggestions. The coffy tastes great🤓

chkdsk /f /c: maybe without the :?

system in use, restart...bios update screen again. scanning 100% complete and waiting... from 0% to 100% two minutes, from 100% to ready..... long wait
