Pavilion dv7 fingerprint reader stops working after several hibernate/suspend cycles

After severl hibernate cycles, the fingerprint reader on my Pavilion dv7 latop stops working. The indicator LED no longer flashes (in either colour), and nothing happens when I scan my fingerprint. I'm forced to revert to password login.
This has been an issue since getting the laptop. Fingerprint scanning works fine at first after a reboot, but when I hibernate (or, for that matter, suspend) the laptop after using, I'm never sure whether the scanner is going to work when I restart it. Sometimes it does, sometimes it doesn't, and the only way that I've so far found to fix it is to reboot.
I've tried using installing the latest driver from HP's support site, although it seems to be dated May, 2011, and, interestingly, claims to fix a problem with not restarting after several hibernate cycles (hint: it doesn't). I've tried uninstalling and then re-installing the driver. Doesn't seem to make much difference.
Laptop is an HP Pavilion dv7-6166nr with Windows 7 64-bit Professional installed (although the problem was present with the factory-installed Windows 7 Home Premium).

Try downloading and running the HP Support Assistant if you have not already. It can search for updates for you specific to your notebook. Here is a link to the download: http://goo.gl/gvpTr

Dv4t-1200 CTO Digital Persona Fingerprint Reader stopped working

I recently posted a question in the Windows 8 Expert Day forum, thought I was getting somewhere, and I think it either got too complicated or the Expert Day was over, so no more help. Don't know.
Here is the link to the full post, so that you can have full information of what has already been tried:

I was hoping that someone might have further suggestions on the Service installation section in this inf is invalid message I keep getting while trying to install the drivers for the device.
I appreciate your help.

I got this reply from DigitalPersona:

W540 - Fingerprint reader stops working after sleep

Once again the fingerprint reader stopped working.
When I run the Lenovo Solution Center (v2.7.003 rev 19975) all appears normal. When I go to [Security]>[Fingerprint] I get a <Status> that it is enabled.
However when I [launch] > Fingerprint Manager Pro (v8.01.35 x64) I get the device is not connected.
See the pictures.
This occurred after coming out of sleep, and warm boot or cold boot did not change anything. It's now been 3 days. I have no idea what the hardware is doing as there are no lights. I did not install any new software, aside from the normal AV updates (MS Security and Malwarebytes ONLY! each aware of the other).
Administrative event logs do not reveal anything.
Device manager has no warning, neither does it show the fingerprint reader.
Scanning does nothing,
Any workaround ??? Any one else with these symptoms. I can deal with software, and drivers, but I cannot deal with failure to have hardware switches, lights, and other missing workstation attributes.
re: Lenovo W540 20BG, 32gb, Win 7 x64, BIOS 2.17, Samsung 1tb EVO

It's an on / off issue. Partly software and hardware. I think it a USB / reader problem. Only occurs occasionally when going to sleep. I do use Zentimo, so that may cause a disconnect when sleeping or at the very least let me know that a disconnect occured. I just type my user PW, as the reader's surrounding surface is now glossy, Never had that problem with other high gloss chassis. Oddly the track pad is immaculate and not shiny!
Reader resumes - in most cases - after cold boot with power off for a while. If I do a warm boot, the reader remains innactive and disconnected.
So far the machine from a software side is tamed and works great, it the harware interface with the internals that is a POS.
If the machine works great, it's because of Intel, nVidia, Micron, etc. The user dialog to the hardware is missing when PROBLEMS (not issues) occur.
Thank you for your concern. Hopefully these issues will be resolved after my yearly update. Albeit, Win 10 concerns me <vbg>. I think MS Win 10 will go the Adobe route, with a yearly subscription after the free 1 year.

Hp Envy Dv7 fingerprint reader stopped working ! what should I do?

Fingerprint reader of Hp Envy Dv7 stopped working after I downloaded and installed an update as Hp support assistant showed a message

I understand the fingerprint reader quick working after an HP Support Assistant update.
What was the name of the update that was applied?
What is the product number?
NOTE: Do NOT provide the serial number.
If you perform a system restore to a date before the update, does the fingerprint reader work?

Pavilion dv7 fingerprint reader not working

Hi.
My HP Pavilion dv7 fingerprint reader isn't working. I have the SimplePass software that's powered by AuthenTec. When I open the SimplePass software, it doesn't seem like it knows I have a fingerprint reader.
I've tried installing new drivers but I can't seem to get anything to work.
Any help is really appreciated.

lyscarn,
Could be the order in which you are doing things, could be the HP SimplePass version would be happier on a different version, could be that you just need to kick the system (metaphorically speaking).
Assuming you are running Windows 7 or Windows 8 AND that you are not running Digital Persona
then
the following may help.
Find, open, and follow the instructions in the file named: Simple Instructions to Upgrade HP SimplePass

Ideapad U460 fingerprint reader stopped working

A few weeks ago the fingerprint scanner on my girlfriend's U460 stopped working. She was deep into a major project at the time so I wasn't able to really look into it until now. To the best of my knowledge no new software was installed around that time and the only updates would have come through Windows Update.
The software does not recognize that the fingerprint scanner is connected. I uninstalled the software, restarted, and installed the latest version (5.9.3.6245) for Windows 7 64-bit from the lenovo download page. The problem seems to be that either Windows isn't detecting the hardware or that it's been given a generic driver and I can't find it. There's nothing in the device manager that appears to be the fingerprint reader.
Normally with these symptoms I'd assume the hardware has gone bad, but looking for solutions there seem to be a lot of issues with Lenovo fingerprint readers. I just haven't seen anything about what I'm seeing specifically. Any ideas?

hey louiedog,
is there anything in the device manager called "security devices" ?
if there is, could you check if there is anything listed in it ?

FIngerprint reader stopped working after windows automatic updates

Hi,
I recently purchased an Envy j109tx laptop.
From day one the finger print scanner was not working.
After updating hp simplepass it started to work.
Again today I installed some windows update. After that it stopped working.
The light in the fingerprint reader is not turning on.
Is there a fix for this?
Someone please help me.
Thanks in advance.

@naga5speed ,
Hello and thank you for posting on the HP support forums. First thing did you do the windows update due to your system having some issue?
If not then do a system restore back before the update.
It is probably some microsoft update that is conflicting with the driver.
It is good to keep your system up to date. But it is better to make sure before you run an update that you take a look as to why you are updating.
Do I need to fix an issue?
If i do not do the update will something stop working?
Using Microsoft System Restore (Windows 8)
If this fails to work then you may have to back up your data and run a system recovery. The reason for this is what ever update you ran has made changes to system files or the registry that a restore will not fix.

X230t Fingerprint Reader Stopped Working

It seems the fingerprint reader on my x230t decided to stop working. Running Windows 8.1 Pro x64. Device manager lists a "TouchChip Fingerprint Coprocessor (WBF advanced mode" under Biometric Devices and that's it. BIOS claims there is no fingerprint reader installed under the security tab, and the Lenovo Fingerprint software cannot detect the reader, either.
I appreciate any help!!!

HI Anthony, welcome to the forums,
you might like to add which operating system you have installed, which browser(s) you are experiencing the problem with and of course which version of the password manager software you have installed.
If you are using the chrome browser it would appear that a recent chrome update may have caused some issues.

Hp pavilion dv6-7020us speakers stopped working

My speakers stopped working at some point but I don't recall any programs or updates that may have caused this. I have uninstalled everything that I know was recently installed. I have run a driver update for the items in device manager pertaining to audio.
This question was solved.
View Solution.

Hi,
Try the following.
Download the IDT Audio installer on the link below and save it to your Downloads folder.
http://ftp.hp.com/pub/softpaq/sp56001-56500/sp56155.exe
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When complete, restart the notebook and let Windows fully load. Open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, right click the speaker icon in the Taskbar and select Playback Devices. Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.
If you still have no audio, open windows Control Panel, open Administrative Tools and open Services. Check that the following services are all showing as Status= Started and Start-up Type= Automatic
Audio Service
Multimedia Class Scheduler
Windows Audio
Windows Audio Endpoint Builder
If you need to make a change to any of the above, just right click the service and select Properties, then in the dropdown box next to 'Start-up type', select Automatic and click Apply to save the change. Then click the Start button.

X230 Tablet fingerprint reader stopped working

Hi,
I am suspecting a hardware failure, but wanted to check the forums first anyway.
I have an X230 Tablet running Windows 8.1 Update. Fingerprint software 6.0. Was working fine (i.e. swipe to power on and log on to Windows and the Lenovo Password Mgr) until this morning. No more green light on the sensor, no function. Windows says that the fingerprint sensor is not available.
It was still showing up in Device Manager, I uninstalled it as part of some troubleshooting and it's not being detected anymore now.
Any ideas other than hardware?
Thanks,
SA.

Turns out I can't get into the BIOS... I suppose I locked it with my fingerprint. Talk about a catch-22.
It does ask for my BIOS password when cold booting (which is the same as the administration password I believe).
Is it a sign of larger trouble? Any way to override the BIOS access restrictions from within Windows?

Fingerprint reader quit working PLEASE HELP

Help! I have tried seaching these forums, and nothing has worked.
My fingerprint reader was working fine this morning when I signed into windows. A couple of hours later, it just stopped working. HP Simple Pass seems to not even recognize it anymore.
I have tried restoring my system. Did not work.
I have tried re-installing the driver for the fingerprint reader from HP. Did not work.
Biometric Devices does not even show up in my device manager.
I am stuck, and I would really like to have this working again. Any help would be GREATLY appreciated.
I have a Pavilion dv6.
Model #: A3E82AV
BIOS: F.26 - 04/03/2013 (0790100000205710000620100)

Thank you
This question was solved.

You did not state your OS: Assuming Windows 8 - 64bit
HP Pavilion dv6t-7000 CTO Entertainment Notebook PC Drivers & Downloads
Assuming you are on the latest HP SimplePass as shown on your website --
this is important and where you need to be:
sp61399 HP SimplePass V6.0.100.272 Win7-8
NOTE: This version runs on Windows 7 AND Windows 8
==================================================================================
When you say that you reinstalled the Driver from HP,
Did you download and install the driver from your Website?
Validity Sensor Driver:
sp58900 Validity Sensor V4.4.234.0
==================================================================================
You might try the following:
Notebooks- Power Reset to Resolve Hardware and Software Issues- Sealed Non-Removable Battery
OR
Notebooks - Power Reset to Resolve Hardware and Software Issues - Removable Battery
The Power Reset cannot tell the difference between drivers - it does not analyze a driver before applying it.
EXAMPLE:
If the driver on disk is the wrong driver before the Reset, it is still the wrong driver after the Reset.
If the driver INSTRUCTIONS are tangled, messed up, or missing, then the Reset may fix the problem.
Why a Power Reset works to fix some issues:
The Power Reset does not install anything on your computer, it does not remove anything from your computer, and the Reset does not "change" anything on your computer. Your data and programs remain as they were before the reset was applied. The Reset drains out the old instructions and makes the computer go to the Operating System on disk to get new instructions.
Why a Power Reset might Not Work:
If the issue is more than just entanglement, if the "good instructions" on the computer are not good enough -- that is, you need an update, a new driver, or there is a problem that cannot be "untangled", then the Reset will not work.
If there is a hardware problem the Power Reset will not work.
===================================================================================
If No Joy:
Assuming that you can at least now see the Validity Sensor Driver in Device Manager > Biometrics
Then
Download your Validity Sensor Driver:
sp58900 Validity Sensor V4.4.234.0
Open Control Panel > Device Manager > Open your Biometric Devices >
Right Click on your Validity Sensor Driver > Uninstall (AND Tick to delete)
Reboot the Notebook and log in
Install the downloaded Validity Sensor driver
Reboot the Notebook and log in
====================================================================================
A suggestion:
Do not skip the requested reboots...
Good Luck!
