I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

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

Connects to USB-C accessories to expand computer functionality. To purchase USB-C accessories, go to https://www.lenovo.com/accessoriesNote: When the battery power is below 10%, the connected USB-C accessories might not work correctly. I've tried looking for accessories for IdeaPad C series and no results are showing?

A:Touchpad not working on ideapad 300. How do I fix ...

Hi there, Tom ?
 
Thank you for writing in to the Lenovo Forum - happy to have you here today.
 
Just found the same problem with my Ideapad 500. Touch pad completely non responsive.
Under start menu, settings, devices, mouse & touchpad, additional mouse options, elan tab. The elan touchpad settings were completely grayed out and unavailable.
 
So from there I went to the window search in the task bar and typed in "computer management? and opened the computer management desktop app. Under device manager selected mice and other pointing devices and then elan input device. In the elan properties window that opened I selected uninstall to uninstall the driver and in the next box that opened warning that the driver was about to be uninstalled l checked the delete driver and then OK.
Then restarted windows. In the process of restarting windows detected the elan touchpad as a new device and installed the driver in time for the login screen. So my elan touch pad is now working again.
 
I am assuming that the driver had been corrupted in the upgrade from Windows 8.1 to 10
 
Touchpad driver for windows 10
Touchpad driver for windows 8.1
 
Update us how it goes.

My laptop stopped working and I have started troubleshooting it today and have hit roadblock after roadblock trying to figure out what could be wrong.  When i turn the power on the power button turns on and the LEDS on the indicator bar at the bottom turn on but the screen turns off. I have tried to hard reset. I have removed the battery also to hard reset. Also has not worked. Tried connecting to the AC adapter after testing the AC adapted itself which is still measuring at 20V and the screen will flash white for a second when its plugged in without the battery. I checked the heat sink to make sure it was working and it si working fine. When I removed the fan though the thermal paste underneath was less than minimal and it fealt greasy. I don't think my CPU would have burnt up though because though becasue my system should have responded and triggered to shutdown. Everything is plugged in appropriately. All my memory is appropriately placed and nothing traumatic has happened to this laptop. Has not been dropped, stepped on, nothing.  I'm concerned maybe my motherboard shorted out but I feel liked that would be a little extreme. Do you have other suggestions for troubleshooting? I'm leaving it on the charger overnight before I mess with it again tomorrow! Thanks!

I have this problem with an ideapad that was handed down to me for repair. The touchpad doesn't work. It came with Win 10 preinstalled, and also the ELAN driver.When I try to use the touchpad, it does nothing. The clic button works, so if I disable the touchpad with the Fn key, it disables it (that way I know it's not disabled when I try to use it). Using a USB mouse works just fine. I did everything I found in the forum: reinstalling windows, the drivers, using older drivers, updating the OS, changing sensibility options and so on, but nothing seems to work.I'm pretty desperate, since the phone assistance didn't solve my problem either. So, help me guys, please?

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

Okay so, I got my Lenovo Ideapad Y500 a couple days ago. Liked it and all BUT when I had my mouse connected into the laptop and then turned off the touchpad, it would not turn back on. The only way I could get my touchpad to work again is by restarting the computer, which is pretty frustrating. I searched this: http://support.lenovo.com/en_US/downloads/default.page?   for ANY drivers/software for the Y500 mousepad and there are none. Can anyone help me fix this problem before I get a refund from this potentially bad purchase? FN + F6 toggles the touchpad on and off and I have tried to turn it on and off, with and without the external mouse connected.
