Q: Lenovo Yoga 2 Pro keyboard stops working when I extend or cast to a second (Samsung) monitor

I recently purchased a Samsung monitor, Model A2514_FPN for my Yoga 2 Pro laptop. I have no problems getting it to work as far as extending my screen goes, however when I do, I lose serious functionality, including my keyboard. Any help troubleshooting this is greatly appreciated!

Hello, I bought my first lenovo computer and already ran in a few issues which I fixed after sometime except one that I cannot find anywhere. When I press a button on keyboard the touchpad locks for a single second and that really annoys in a graphical applications or games. I found a few posts that people fixed on older lenovos with turning off on palmsense on elan pointing device, but when I did it on the newest version it changed nothing so I decided to uninstall ELAN software completely and I got into another problem, that gestures don't work of course and now it got reversed but have the same problem still can't use them at the same time. How to fix this issue? Computer:Yoga 710  14 Lenovo i7-7500U/8GB/256GB/IntelHD 620/W10/Black

I have a problem with my Thinkpad Yoga 460 which started to occur about 2 weeks ago. Sometimes after bootup the keyboard does not work when I have to supply my passphrase for the hard disk encryption. The solution I have in this situation is to turn the battery of in the UEFI setup. Then pressing the power button for 10 seconds and then enabling the battery again with the power cable. This works reliable to fix the issue, but it is very annoying and when I am at the university there is no socket to enable the battery again. Is something broken or is there a workaround for this issue?

For about a week now, the keyboard has just stopped working randomly several times a day and without any pattern that I can see.  Although the PS/2 keyboard keys stop working, the virtual keyboard still works and so does the touch pad/mouse. In order to get the keyboard functioning again I have to restart.  Windows 10 has been installed and working for almost a year (of course with the usual adjustments required after upgrading from Windows 8.1). I have Bitdefender Total Security 2016 and the system is fully updated and patched. I have followed all the instructions/solutions I can find on different forums. These include: virus scansScannowupdating/reinstalling the driverschecked Bios version is up to datechanged Ease of Access keyboard settingstried windows plus spacetried task managertried Windows trouble shootermade a reliability scan (this showed several errors labelled Microsoft.Messaging_8wekyb3d8bbwe!ppleae38af2e007f4358a809ac99a64a67c1 . It is apparently linked to Skype Host).The issue is unresolved (it is only midday  and it has already happened twice today). I see there is a similar post on a forum for Yoga 3 users, but the solution there appears to have been an update for the Yoga 3 system.  If anyone has any other ideas, I'd be very grateful. I have spent ages trying to track down a solution. Thanks, Sek

Hey CommunityI encountered a rather strange problem yesterday when my wife turned on her Lenovo we bought a month ago. It is possible to enter the PIN at the Win10 startup page, but as soon as we enter Windows, no(!) key works. Neither Keypad nor Keyboard.We tried:- accessing the Bios, which works and in which the Keyboard works normally- deleting the Keyboard PS/2 Driver from the Hardware Setting Menue, which results in a re-installation of this driver but still the error remains- plugging in a USB keyboard which interestingly receives power and the volume buttons works, but here the same, the keys do not function (and this one also does not work at the windows pin screen).- waited until Win10 installed all updates, even the anniversary update, but still nothing changed (was my last hope. D'oh!). Right now I'm quite lost and don't see why things do not work. Really need some help here...Thank you in advance BTW: It's a  Lenovo B50-80 80EW0521GE as far as I understand it.

Hello there all, I hope you are having a nice day/night while reading my post  Recently Im having a quite uncomfortable problem with my Lenovo. As the title says, it stops running, to be honest, mostly when playing League of Legends. Very rarely while doing other things, like surfing on the web, perhaps more often when playing other games than League It's hard for me to figure up, why does it happen. My laptot is fairly new (4-5 months), and it has not been damaged or awashed by water And there we go to the second problem, which is connecting with WiFi. It just randomly does not show any will to connect with web spots. Sometimes, it works just fine. I installed WiFi/Router drivers, and it hasn't got any better The third, and the last problem is, that my headphones sometimes don't run. Rather randomly, when I plug them in, or when I turn on the computer while they are already plugged If anyone can help me with any of these problems above, I will be very grateful My operating system is Windows 10

Hello all! I write to you today from an external keyboard placed on top of my laptop, because my keyboard stopped working last night, first by losing an e key, than a r key, and then, when I restarted the laptop, thinking it would be solved by doing so, the entire keyboard would not work past a certain point in windows boot. It does work in BIOS and I can even watch caps lock light up and go off and turn the backlight on and off.Things to note1) The last software change was 2 days before this happened. It was an update to Windows 10. which is my OS.2) My system restore points will not work due to an issue with AppXstaging (not sure if solvable).3)There are two HID compliant devices in my keyboard section on device manager. and a ps2 compatabile keyboard (which is the one I'm typing on right now) 4) I emphasize that the keyboard DOES WORK in BIOS and during boot, up until the point I can see my windows icon, and Cortana. Things I've tried1) sfc scannow comes back with there being issues it couldn't fix as well as ones it fixed2) chkdsk enjoyed scanning my computer for 5 hours last night and fixing some issues3) I do have an event viewer full of errors regarding filter manager and storage, but nothing I could see with the keyboard.4) Black majik5) I have uninstalled so many devices from device manager to let them install that my mouse hands hurt. Perhaps the place in the boot process it is freezing is when the driver reinstalls?6) The problem still occurs in SAFE mode... Read more

A:Lenovo Y50-70-- Keyboard stops working during wind...

Hi Rose,
 
Welcome to Lenovo Forums.
 
About the keyboard issue I am not sure. I have heard that there is another Patch update for Win 10 that has been released, you may want to check and install that in Windows Update functionality.
 
Method 1:
Try to remove keyboard device via device manager (right click my computer > manage > device management > keyboards > find your keyboard > right click and select remove > then restart your computer)
 
Method 2:
If the keyboard is working fine on the login screen and then suddenly stops functioning when you get to the desktop / metro screen then the problem might be with the Filter Keys - similar to this thread.
Try to turn off Filter Keys by going to Control Panel > Ease of Access > Ease of Access Center > Make the keyboard easier to use > uncheck Turn on Filter Keys then hit apply.
Link to picture
If same problem, you may want to consider doing a clean windows.
 
Method 3:
If it doesn't work, you may need to replace the keyboard, contact Lenovo service centres and ask for replacement for free if you have valid warranty.
 
Let us know how you get on.
Regards,
Shashi

Hi everyone, I bought this laptop about 3 months ago and I'm loving it so far. But every so often the keyboard would just stop working and when I try shutting it off, it would go through the entire shutting off process and the screen goes black but all the lights and fan would still be on. I am then forced to hold the power button down to force it off. When I restart the computer instead, it would take me to the blue screen where it would say "Windows has ran into an unexpected error" then the screen would turn black again and everything else would be on. Anyone have any idea or solution to what's going on? Thanks in advnace!

So I booted my PC after an update the other morning and the keyboard and trackpad weren't working. I tested the brightness keys on my keyboard and they still worked so it couldn't be a hardware issue there, and my mouse still worked so it was just the trackpad that had something wrong with it. The trackpad has a driver error (code 10) but the keyboard says it's working correctly. Here's what I've tried in hopes to resolve the issues so far: -Reinstalling trackpad drivers -Uninstalling both trackpad and keyboard drivers then restarting -System Restore -Chkdsk on both drives -A trick I read on these forums where you flip the device into tent mode, then after a few seconds flip it back round to laptop mode. I am utterly confused as to what's wrong here as nothing has even slightly helped my problem.

I have a Lenovo Yoga 700 14ISK (ideapad) with Windows 10 64bit, whose keyboard and touchpad are refusing to work.Everything else seems to be running smoothly except for these. I initially was getting by via the on screen keyboard until I began borrowing an external wireless one. The following is what I knowReset to factory settings did not work.Optimizing OS in BIOS is enabled already (enabling this was suggested by Lenovo Support)THE ARROW KEYS WORK IN BIOS (??!???!?)An external keyboard works (I have used two different Logitech keyboards and both work)Before I sign in, FN+Space seems to work thus (re)activating my backlight. Once I sign in, it stops working.There's no updates for the keyboard driver.I have already tried to uninstall the driver, restart the laptop, and allow it to reinstall the driver.Disabling ymc did not help.F6 does not re-enable the touchpad.I tried a couple button combinations I've seen around for people disabling/enabling keyboards, but none worked. (Willing to try more though!!!) Any ideas? I thought it may be a hardware problem, but since the arrow keys work in BIOS; I'm not confident that this is the case.

Hi all, I bought a Lenovo S1 Yoga. The shift key only works with certain keys but not other, important ones like T. It is extremely inconvenient and makes this laptop unsuitable for work. Characters like the semi-colon are completely unavailable on this laptop now. I have already read through quite a few forum posts to find the solution. I have tried using the device manager to uninstall the keyboard, have used Lenovo vantage to find the latest drivers and install them and have also tried turning all keyboard ease of access ommands off. Nothing seems to fix this issue. It seems to be a software issue, rather than Hardware as the shift key works with about half of the keyboard. It does not fix itself when working on the command prompt. Please could someone provide an adequate solution to this problem. Thanks,SZ

A:Can Lenovo Yoga 520 extend to 2 monitirs?

Video output by USB-C is separate standard than USB-C itself, so laptop will support it only if it was clearly said in specs, and if it supports USB-C video output, it usually support it on only one port. But you can still (even if you don't have such special port) connect USB-C or even normal USB external GPU, which will be of course really poor at performance but will provide additional video ports.

Hi
We installed a nice new Samsung LED TV Monitor last night #T24A550 and the keyboard and mouse were both working ok for a few minutes, then everything froze and now they won't work. I think it's both that won't work but it might just be the keyboard. The system boots and the windows screen comes up but I can't click anything or even manipulate the keyboard. EX: I can't turn on/ off 'number lock'. I unplugged both in back, turned off the computer. Then back on and rebooted and still nothing. I am running Windows XP Home edition. Thanks!!
 

A:Samsung LED TV Monitor - now no mouse or keyboard!

Are the mouse and keyboard USB or PS2? If they are PS2, are they in the correct ports for their type? (Keyboard in the Keyboard port, and the Mouse in the Mouse port, and not vice versa) If PS2, did you turn off the PC before disconnecting and reconnecting them?

How is the TV connected to the PC? Is it a standard VGA connector, a DVI connector, or a HDMI connection, or a mix of these connectors?

Please examine the cable and connectors of your TV, Mouse, and Keyboard cables. Is there any damage or bent pins?

A:Keyboard stops working - USB external keyboard is fine

Hello Nysoh

On this virtual way nobody can say for sure what the problem is but if the internal keyboard is not working properly first step is keyboard replacement. If the problem still persists then troublemaker can be keyboard port or keyboard controller.

As far as I know BIOS has nothing to do with this issue.

I just recently purchased a Yoga 14 primarily for the active digitizer screen so I could do design work on the go. My laptop has the pen that comes with it, and when I take it out of the slot, it works fine. However, when I use it for roughly 3 or 4 minutes, it just stops reading on the screen. I can reinsert it into the slot, take it out, and it will work for another 3 or 4 minutes before I have to do it again. It never displays a low pen battery indicator, and every time I check the battery using the application, it says its good at 90 to 100 percent. I have updated drivers as well, but still can't fix the issue. The touchscreen otherwise works perfectly when it is active, and always responds to touch. Seeing as I purchased it for the ability to draw with the pen, it's kind of inconvenient that it works for very little time.

I just received a new Lenovo Y900 SUS. It came with a gaming keyboard and mouse. Every single time I changes user accounts (multiple family users setup in Windows)- the keyboard stops responding. All the lights stay on but none of the keys do anything). If I unplug the keyboard and plug it back it- it starts working immediatly. (One time the keyboard has stopped when I was doing something other than changing users but EVERY time I change users it stops working). I have tried changing the various USB ports -but it happens regardless of where it is plugged in (out front of tower, out back, USB 2.0, USB 3.0). Driver is up-to-date and appears to be correct for the model (or at least- I cannot find any other driver). Any ideas what else I can try? Is it a lemon- should I request a new keyboard or is it some setting somewhere I haven't thought to try? Thank you for your help!
