T420 WWAN+Finger Print Reader not in device manager?!?

Hi,
Im new to lenevo and this is my first one..its a Lenevo T420 4236P3G. I have been advised by Lenevo support that my machine is WWAN compatible and has a Ericisson 3G card built it...I also know it has a fingerprint reader which is clearly on the machine.
Problems I have
1) The sim card slot behind the battery seems really odd!? I KNOW if I put my sim in there it will just be lost forever. There seems to be no "click" in and out mechanism..Iv tried with a dummy sim with a string attatched and it defo does not have a click to it...If I put a normal sim in it would just be stuck forever..
2) I have a fingerprint reader and WWAN built in..BUT both of them do not appear in the device manager?! There are no devices which are unreconized and everything is accounted for so its defo not a driver problem...they just dont physically show!!
Iv already updated the BIOS, used lenevo update, tried both Legacy and UEFI bios options in the bios...
Only thing that it may be is my machine has a clean install of Windows 7 pro..Support have said they are sending me out copies of the original recover disks but I just dont see this working?!?I mean if they have disappeared and are not even picked up by the laptop in device manager then how will they run through a different install???
Tried using google but been no help..hope someone here can give me a hand
Thanks in advance

Sd card reader not in device manager

Hi,
I have recently formatted my HP DM1 4118au, and after which, my SD Card reader was undetected by the Device Manager.
I have tried to install the Driver but it's still not detected.
Any otherway to make it work again, or to diagnose what is wrong?
I am afraid it is the hardware itself and not the reformat.
Please help.
Thanks in advance.

HP Pavilion M7 Finger Print Reader Not Working

Hi,
I recently purchased an HP Paviolion M7.
I put an OCZ SSD in, and ended up doing a fresh install using non-HP Windows 7 (64). Using the HP Recovery Tools is simply not an option (believe me I tried).
I have everything working now, except for the Finger Print Reader. I have tried everything I can think of and could find.
I am using all the drivers/software from:
http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=4063&lc=en&cc=us&dlc=en&sw_lang=&product=5273...
I have done these things:
https://support.authentec.com/Forum/tabid/318/forumid/49/threadid/600/scope/posts/threadpage/2/Defau...
http://h30434.www3.hp.com/t5/Other-Notebook-PC-Questions/HP-Pavilion-dv7-4020sa-finger-print-reader-...
And more.
I believe the issue is because Biometric Device is Unavailable to Windows, see this screenshot:
I believe the above picture causes the Authentec HP SimplePass software to not recognise the driver version, see screenshot:
Any ideas?

I am sure they are the correct drivers, they worked with the system when it was an "HP" version of Windows.
The screens work for me, here they are again:

HP Envy Touchsmart 15 finger print reader not working

Hello, I've had my HP Envy touchsmart 15 for little under a month now and it's been going great until yesterday and today, the finger print reader hardware has started acting up.I log into my account fine and then when I leave my laptop for a little bit, I then return to log in and it won't let me use the finger print reader, it doesn't flash red or white, it just stops working. So I then try to log in using my password but I can't because it's saying my finger print is not recognised and keeps flicking bad and forth to that message. So basically it seems to think I'm rubbing my finger over it when i'm not even when the lights aren't flashing or anything and to solve this I have to power it off with the power button, which is not ideal at all. This is a problem, any help?

I've had this issue on and off with my laptop, as well. It has persisted through Windows 8, 8.1, and even started up again after upgrading to Windows 10 this week. I've also done the Simple Pass uninstall/reinstall thing, as well as used updated versions of such with the problem recurring. I reloaded a fresh install of Windows 8.1 earlier this year, only to have the problem persist. This week, I decided to forgo the HP software entirely and start using the Windows Hello feature that allows Windows to natively access the fingerprint reader without any other software required. Here's what I have figured out:The issue seems to be caused by the activation of a power saving profile at shuts down the fingerprint reader out of perceived conservation. Disabling this feature seems to have wholly rectified the issue.Windows 10 has installed the most recent Validity Sensors driver for the device, and it seems to work well.Here's how I fixed it, which should work for you:At the risk of shilling for Microsoft, run all the Windows Updates needed to get your PC to prompt an update to Windows 10. (The HP software seems to be at least partly to blame, and I hated the latest iteration of Simple Pass.) The Windows Hello feature should work well, as this device is supported. All instructions below assume you have installed Windows 10.Before continuing, uninstall HP Simple Pass from the control panel or through the new Windows 10 applications window (in Settings).If you have the "My Computer" icon on your desktop, right-click it and select Properties to open the System window. Then, select "Device Manager" from the upper left column of the System window. (If you don't have the icon on your desktop, type "device manager into the search/Cortana dialog on the Windows taskbar, and select the top/highlighted result.)In the Device Manager window, click on the small right-carat next to the "Biometric Devices" entry.Right-click on the Validity Sensors entry, and select Properties to bring up a device properties window.First, select the Power Management tab at the top of the dialog. DESELECT the checkbox marked, "Allow the computer to turn off this device to save power."Next, select the Driver tab. Click on the Disable button near the bottom of the dialog.Press OK.Again, right-click on the Validity Sensors entry, and select Properties to bring up a device properties window.Again, navigate to the Driver tab.This time, select the Enable button (where the disable button was previously). Press OK to close the dialog. (Your fingerprint sensor should flash a couple of times, but don't worry if it doesn't.)Close all of the windows you have opened.Open the Start Menu and select Settings.Click on Accounts at the far right side of the window.Click on Sign-in options in the left-side list.Under the Windows Hello heading, follow the step it gives to set up your fingerprint reader.Since doing so, I have had no further problems with the fingerprint reader. It seems to work reliably, but I'll update this post if I run into any issues. Good luck!

Photosmart 2575 stopped working gone offline not in device manager

Hi my hp photosmart has suddenly stopped working.
1. I am using vista
2. It does not show up in device manager
3. Printer icon has green tick on it and says offline. When I try to print the printer icon appears in the tray. When I right click and open up HP Photosmart 2570 series my documents are queing but nothing is happening. It says "error printing" and when I click restart it says "error restarting sent to printer"
4. I cannot find the program to uninstall/install
5. I have tried a system restore.
Please Help

I had a similar problem. I solved it by installing the Apple Bonjour printing service:
http://www.apple.com/fr/support/bonjour/
and use it to discover and add the printer... (you can then get rid of the old greyed-out printer)
It's based on the mDNS protocol (aka ZeroConf, aka Bonjour) that the HP Photosmart supports.
No need for a fixed IP or fidling with DHCP with this...
You should be able to see your printer in your webbrowser by simply typing http://hp02cd83.local/ (or whatever your printer name is)
Hope that helps!

Satellite Pro L300: WLAN is not in device manager and is missing

Hi,
I have a Toshiba L300 which I downgraded from Vista to WXP months ago. So I decided to stick with Vista and when I installed Vista the WLAN was missing in device manger and it didn't work. I tried downloading drivers adapters from Toshiba drivers download and still didn't work. Only my Ethernet is showing in device manager....btw I have a Realtek WLAN
Also,my VGA graphics card doesn't seem to update driver and when it does it says that the system is below minimum specs.
It's soo weird in WXP it was working fine..... Any solutions?

>I tried downloading drivers adapters from Toshiba drivers download and still didn't work.
What does it mean exactly? Have you installed WLAN driver or not? Is WLAN card installed properly and listed in device manager as Realtek WLAN card?
How to understand you?
Have you problems to install WLAN card or to configure WLAN connection?
If the WLAN card is installed properly enable the card with WLAN switch and then use FN+F8 key combination and be sure card is set to ON.
Which display driver you want to install? Which version?

'Unknown device' in Lenovo Solution Center, but not in Device Manager

Even with all the latest updates installed, I still get this annoying warning from Lenovo Solution Center
'Unknown device' - status 'not installed'
Control Panel / Device Manager gives no signals something is wrong.
why?!
Details:
Computer: Thinkpad Yoga (TPY)
OS: Windows 8.1 all updated
Lenovo Solution Center version: 2.2002 / revision 17630
External device attached to TPY: OneLink Pro (also has latest driver = Realtek 8.10.1009.2013)
Thanks in advance

It seems to me you are missing some update from Lenovo. I had the same issue, however just recently after updating any available software/drivers for the TPY the message has disappeared.
Glad to hear the problem is solvable. Regarding missing updates, I honestly would not know which one.
Lenovo's own update programs ('L-Update and Drivers' & 'L-System Health and Diagnostics') inform me that all drivers are up to date.

Web camera fails to initialize, not in device manager

Hi,
I have a Satellite L650D with Windows 7 'Home Prem' and have recent issues with my webcam. All was running smoothly for a year or more until one day this error message appeared " Web camera initialization failed. Please restart application or computer ".
I also had trouble on Sykpe with the camera failing mid-conversation then not loading at all. I have un-installed and re-installed Skype in the hope that it was the problem...unfortunately not. Then after searching through the forum and Toshiba's website, I checked my application and Device Manager and was not even able to locate the device, it is not listed.
I am more than happy to try anything to fix this problem ( although I am not very computer literate! ) and would really appreciate any advice anyone can offer!
Many thanks =)

Gt70 - Nvidia GeForce GTX 675MX - not in device manager?

My Nvidia gfx card seems to be gone entirely. I did uninstall the nvidia drivers at some point, but now it's gone from the device manager as well (see image)? Because of that I can't install the NVidia drivers (let alone the nvidia control panel)
I'm kind of in the dark here? Is it windows 8.1 misbehaving? Is it a faulty gfx card? Any help would be appreciated. Thanks in advance!

I had this issue back in February where it started out with a VIDEO_TDR_FAILURE blue screen then when I restarted my video card was gone from my device manager followed by loud noises coming from where the video card was, like almost as if my fans were going full blast. I have the same model as you, after 24 hours of having the laptop completely off because I was scared of the fans overheating. I turned it back on and the video card magically re-appeared again. But when I tried to play a game it would crash giving me a strange error.
I seriously think Windows 8.1 is misbehaving cause a lot of people who have this same model and video card are getting blue screens like crazy. I got so tired of Windows 8.1 that I down graded to Windows 7, I hope to God that it fixed my issue.

Finger print reader not working 'post' Windows 10 upgrade from windows 7

Ok I have succumbed to upgrading to Windows 10 as I did to Windows 8, perhaps this time I won't 'rollback' but already things don't look good . As a part of the upgrade the Windows 10 the installer spat about the HP Protect Tools Security Manager and asked me to uninstall in order to proceed with the upgrade. I started to get a little concerned from this point on that I would lose my fingerprint reader as a result of going to Win 10 and low and behold that’s happened. It was only after following several threads online that I originally got the fingerprint reader working on windows 7. I went in and out of the BIOS resetting this and that but in the end despite having all the HP drivers for the readers (latest ones) the only thing that ‘fixed’ my fingerprint reader was the installation of the HP Protect Tools Security Software. So the question is where’s the Windows 10 version of the HP Protect Tools Security Software or the ‘fix’ is there one?? Hate to think an operating system is blocking such a great HP laptop feature!

I want to upgrade from windows7 to windows10 (probook 4350s) I have the same question about compatible version, which I hope HP or somebody answer soon and help us...I also cant uninstall my protect tools as upgrade needs me to.I want to know is it possible for finger scanner to work in windows10 after uninstalling HPPTM. thanks,Nazanin Mirzabeigi

T420s WWan Compatibility - H5321gw or not ?

Hi there,
I was looking through the parts lists for my T420s (4174-P4G) and noticed here :
http://shop.lenovo.com/SEUILibrary/controller/e/gbweb/LenovoPortal/en_GB/catalog.workflow:show-categ...
http://support.lenovo.com/en_US/product-and-parts/detail.page?&DocID=PD024213
That the H5321gw clearly comes up as a part for the T420s
Is this a mistake or is this card in the whitelist in our BIOS ? As this card actually has proper Windows 8 drivers and I have one laying around, wondering if I should try putting it in or not.

Looking in the parts manual I am able to find the following:
Ericsson Mobile Broadband Module F5521gw, with FRU Number: 60Y3279
The whitelist will require that not only the card be on there, but it is a Lenovo FRU. You are able to tell this best by ensuring the FRU number is listed physically on the card. I believe the card you are referencing can go into the T430s. Now of course, you can still give it a go and see if it'll work. If does not you'll get something like an 1803 error.(Not 100% on the error code.) But it will tell you to remove it.
