Ideapad C340-14iwl fingerprint not working

Q: Ideapad C340-14iwl fingerprint not working

I recently got a Lenovo ideapad c340 for school and I absolutely love it, but for some reason after it didn't recognize my finger print a single time it just decided to not work anymore (yes I reinstalled the driver and thanks to Lenovo Vantage I'm on what I think is the latest BIOS)Is there anything I can do about this or should I just wait a bit and see if there's some update I can do somewhere in the future?

This issue started when I was setting up my laptop. I just installed DirectX which is required for a software I use when this shadow appeared at the bottom right side of the screen. I thought it was quite odd so I uninstalled DirectX, but the shadow is still there. I tried reinstalling DirectX and it was still there. Sometimes the shadow disappears, for example, I switched my laptop to tablet mode and it was fixed! I felt so relieved when I made it come out of tablet mode and the shadow was no longer there, a few seconds later, the shadow returned.Does anyone have a solution? Even when the laptop is booting up the shadow is still there, I've been very careful with my laptop so I struggle to think of it as a hardware issue. https://imgur.com/gallery/luzN7hK

Hello.I recently bought C340 14IWL I5 8265U with VGA onboard Intel Graphic 620.On the back of the device, I can see two slots to release the heat but only the right side is working. I have reviewed some documents from User Guides, Hardware Maintenance Manual and can see the cooling system with two fans.I also know some version with VGA NVIDIA and I wonder if only these versions have a cooling system with two fans?The reason that I ask this's because I often see fans run very fast and make noises. This is my first time using a laptop from Lenovo so I don't know if it's normal or not ? My previous laptop from Asus was rarely able to hear the noise from the fan.And one more thing. I bought this laptop for 20 days and use Conservation Mode. Is full charge capacity (in Lenovo Vantage/Battery) reliable ? 10 days ago I checked and found 45Wh/45Wh(Design). 3 days ago it suddenly reduced to 41/45Wh, then i turned off Conservation mode and fully charged and now it's increased to 42.9/45Wh. (With 10 Cycle count)Thank you

A:Cooling system Lenovo C340 14IWL

The video below show the inside of the C340 model without the discrete Nvidia graphics, and it does indeed have only a single, but larger, cooling fan than the two fan version.     C340 Fan Removalhttps://download.lenovo.com/lts/RCNW1860/FOF/RCNW1860-IdeapadC340IdeapadFlex_REM_FRU_09_Fan.mp4 More C340 parts removlal/repelacement videoshttps://support.lenovo.com/us/en/solutions/HT508522 I cannot answer you battery questions, but in my experience lithium batteries last longer in conservation mode (lifespan).  Cheers,  Cheers,

I purchased a new Ideapad S540-14IWL recently but couldn't find a way how to connect a secondary display via HDMI. I use Windows 10 Pro. So far I've tried the following:- using different monitors;- using different HDMI cables;- installing newer and older Intel VGA drivers;- going through the Windows 10 video troubleshooter;- switching off the laptop and/or the monitor and powering them in various sequences (as suggested in a few articles I found on the Internet);- tried to switch to the second display using Win+P, of course. No matter what, Windows is not able to detect a connected display (even after I manually push the 'Detect' button). The display itself finds no signal. Surprisingly, the Lenovo diagnostics utility couldn?t identify a problem after running both the Display and the Display Interface tests. The laptop is flashed with the latest BIOS. I read other Lenovo models have similar issued when AHCI mode is selected in the BIOS rather than RST. However, switching to RST comes with a warning that the controller change will result in all the data being erased, which I can't afford.  Any help on that issue will be appreciated.

So I bought  a new s540 without an os. Installed Windows 10, ran automatic updates, installed other drivers manually etc...When I connect the laptop to an external monitor nothing happens - trying on different monitors and cables.I thought I had a damaged product so went back to the store for a replacement. A few days later I got the replacement - same exact problem. The sales representative said it is probbly a problem with the whole line. Is that so? I just returned it to get my money back. Is it a known problem? I see that I'm not the only one having this problem. I've been a Lenovo user for most of my life and would like to remain one. Can you please suggest a fix? I'm not going to buy another s540 / ideapad model until I can find a solution.  Thanks, Samuel

Hello Community,as per a.m. I'm reporting what I believe is a bug, not sure it is though.Everytime I try to update the AMD VGA Driver via Lenovo Vantage (which I find very useful since I do not have to deal with the manual install/uninstall of drivers) I reach a point where the OS reports that two different driver versions are installed (??).There seems to result in a driver conflict, therefore I'm unable to access to the AMD Radeon Settings via mouse right click. Shouldn't the Lenovo Vantage process uninstall the old driver before installing the new/updated one? No updating of drivers via Lenovo Vantage have ever resulted in such a weird behaviour, so I have no clue of what it is... Lucky me I am prudent enough to have a daily backup of the OS so I can restore it when such behaviour occurs... Do you guys still suggest to using Lenovo Vantage to update AMD VGA Driver or proceed with the manual update?Could pls. be so kind to tell why Lenovo Vantage is behaving so weirdly and if it's resolvable or not?If it's not can you suggest a page/guide explaining the manual process of updating the specific driver for my notebook and where to download the correct one?Thank you so very much in anticipation for your kind support. Specs:Windows 10 HomeInstalled/current AMD VGA Driver version: 25.20.14118.3002Latest AMD VGA Driver version: 26.20.11016.5002

I have just received my C340 and activated Lenovo Vantage which found a BIOS update which I ran. It is now running BIOS version 1.6. BUt when I go onto the Lenovo Support page and it automatically and correctly registers my C340, I am informed of a newer version of the BIOS update (2.02). I do not get it. Why is there a newer version here than the version that Lenovo Vantage finds? And what I am supposed to do in a situation like this? Do I ignore that there is a newer version - or do I actually download it and install it? I would like an answer from a Lenovo representative to this issue. Unfortunately, this is not a very good start with this new Lenovo C340 notebook. When I logged in to the support page by Lenovo and it registered the notebook automatically, it also told me that the warranty ran out in 1970. What???! So now I have put in a case for having them correct this. But this is really not a good start

A:Ideapad C340 - just updated BIOS via Lenovo Vantage but a new version available on support page

Hi BlipBlopDK,
 
Welcome to the Community Forums.
 
Each machine models have different variants. Not all updates can be applicable for every variants.
 
With the BIOS, reading the text file first is important doing it manually. If the changes from the older version applies to specific issue you have then you may proceed but if Vantage did not assign it automatically and you do not have any issues then there may not be any need for it.
 
My warranty is showing incorrect dates and duration? Why is this happening ?
If you had purchased your machine from a retailer, business partner, reseller, Lenovo starts the Base Warranty at the time the shipment was purchased by the retailer, business partner, or reseller from Lenovo. To compensate for the time the computer may have sat in a warehouse or on the shelf unsold, Lenovo generally adds an additional month to the Base Warranty, Lenovo allows date to be adjusted.
 
Here is the article that you can follow for the steps. 
 
About the warranty date correction, some stores would do it for you while other may not since buyer may have a different user for it aside from the fact that personal information should be kept privately.
 
I hope this helps answer your query.
 
Regards

NOTHINGhas worked. Spoke to Lenovo Live HelpNothing worked they told me to contact Microsoft. Spoke to Microsoft Live HelpNothing worked. They could not get it fixed. Now after a BIOS update that Lenovo suggested it showed up again but now says:Currently, this hardware device is not connected to the computer.

Hi everyone, I bought this laptop a week ago and ever since am trying to figure out a solution for my problem. While setting up my laptop, I noticed that the fingerprint sensor wasn't listed in the device manager. Also, in the login settings it says that windows hello isn't compatible with my device. Doesn't make any sense since the lenovo shop even states that this particular model supports windows hello with its fingerprint sensor. The activation of the sensor should be able via bios security settings but there are no entries for the fp sensor whatsoever. No activation, no data reset. I don't think that the latest windows update has something to do with it, since it shouldn't effect the bios settings or am I wrong? Kurs

After updating bios, fingerprint worked once but now it stopped working again. And none of the other solutions have worked at all.In the settings it says win hello can't be used in this pc - which is untrue. In the device manager i have the little triangle warning sign on my synaptics wbdi and device status is "cannot be started (code 10)".Real solutions are welcome. Thanks.

Hi all, Would love some help here.The fingerprint sensor suddenly, like literally suddenly stopped working all of a sudden. It was working maybe give and take about an hour before. I went into account settings under sign-in option to find that WINDOWS HELLO is not available for my device?! Then i went crazy all over the web trying to find a solution but to no avail. I have tried all kinds of method the web can find for me like:1) starting the cmd prompt and doing a system scan and health restore something like that which says the system is fine2)enabling the fingerprint driver in group policy3)updating the driver did not solve it4)reinstalling the driver does not help at all5)updating the laptop6)going into BIOS but could not find the driver anywhere7)renabling the driver there was no previous updates to the driver at all, it just stopped working and therefore i cannot do a rollback of the update to a previous version. o and after doing all these, i still cannot get it to work. Is there something wrong probably with the hardware?I just got the laptop about a month or so, hope this is just temporary as i quite like how this laptop is functioning for me now and would love the fingerprint function to be back. Sincerely,A lost carpex
