In addition, the F7 key is not working as well, and the airplane mode is now turn on and I cannot access Internet. I google for a solution and tried to download and reinstall drivers for power management and display card but still failed. Anyone can help? Thanks a lot.

Hello there. Yesterday, I bought the Ideapad 310-15isk, and it's phenomenal in many aspects. However, I'm a bit bothered by the extensive keyboard this laptop has, most importantly, the pagination commands on the arrow keys. I've been meaning to find a solution to disable those and just make them work on the Numpad since it's really bothersome to type on and then go all the way back because of the return pagination key. Is there any solution for this to unbind those commands only on the arrow keys?

Hi! As of yesterday, all three of my USB ports malfunctioned, and whenever I plug in anything new it says "USB device not recognised, The last USB device you connected to this computer malfunctioned, and Windows does not recognise it".  It also shows "Unknown USB Device (Device Descriptor Request Failed)" with a yellow exclamation mark and "Windows has stopped this device because it has reported problems. (Code 43) A request for the USB device descriptor failed" in Device Manager. There's definitely power coming from the USB ports, just they don't respond to anything I plug in, such as my mouse. I've tried everything I can find online about the error, except updating my BIOS.  However, the BIOS that pcsupport.lenovo.com suggests for my laptop also gives me the warning message "This BIOS is only for Lenovo ideapad 310/510 - 14/15ISK(with touch).  Are you sure you want to update this BIOS on this machine?"  As I don't have a touchscreen, I'm not 100% sure it's the right one.  If anyone could please let me know which BIOS update I should install, or (even better) how to fix my USB issue, that would be fantastic.  Thank you!

Hello, I have purchases this laptop 4 months ago and everything has been working fine. However today when I turned the laptop on, the touchpad was unresponsive. I have not made any system updates, or whatever prior to this malfunctioning. It seems to just have stopped working out of nowhere. I have tried uninstalling the synaptics driver and reinstalling, I have tried older drivers and the newest, also the standard microsoft touchpad driver. Nothing seems to fix it, it is completely unresponsive.Might it be a hardware failure? I appreciate all suggestions.

Subject says it all: suddenly I can't screengrab by simply pressing the PrtSc key.  Nothing happens when I do so.  Nothing is running that could be causing this (no OneDrive, no DropBox).  I haven't changed any settings; at least not intentionally.  It does allow me to paste the screen image into a new image file, but no longer does so automatically, which is a problem for me.  Did I accidentally screw up some keyboard setting?  Any ideas?

Hi everyone, I spilled water over my laptop about one week ago. At first, the keyboard was working perfectly, but the next day, some keys were connected (when pressing one, it would display 2 characteres). After some time, those keys that were connected, stopped working at all. It hasn't changed since then.  I am living in USA but my laptop was bought in Spain (it has spanish keyboard), and Lenovo US told me that they can't fix it here, I would have to send it to Spain, which is really expensive.  Is there any other way to fix it? I read online that water can't damage the keyboard, but it has been broken for 1 week, so I don't know if I have been unlucky. Also, the laptop works perfectly with an USB keyboard. Thanks.

A:Lenovo ideapad 700-15ISK keyboard not working after spilling water

Water can certainly damage the keyboard.  There are 2 layers of conductive film and water gets inside.  That seems crazy that they cannot get a Spanish keyboard in the U.S.  I would try to get a second opinion.

Hi!I bought an Lenovo IdeaPad 510-15ISK Model:80SR and like other customers i have the same problem on this model with the gpu nvidia 940mx being at 100% usage but core clock speed and memory speed being at 405mhz (when base is 1122 and boos is 1242mhz). First i want to mention that i updated my BIOS version to the 2017 feb (latest for this model) and still have the same problem. The gpu core clock never goes above 886mhz and it usually drops at 405mhz and the memory as well.Like the others said on the forum it seems the problem is from lenovo bios settings where is set that gpu cant go above 62 degrees and when it does the gpu drops to 405 mhz making the laptop useless in games.Also it seems the only solution is an bios  update from lenovo that never came. Also I saw that the support never responded to this problem. I hope someone from lenovo will give me a solution to my problem.I still have my warranty and i'm thiking about money refund or laptop replace model if the problem is not fix because the laptop is not working in the parameters it should work and i wanted the laptop for light gaming

Hi, the latptop is only about 2.5 months old now... 3 weeks ago randomly the keyboard's keys on the laptop itself stopped working. No clue why, Ive checked drivers, did a reboot, tried safe mode, etc... It's only on the laptop itself. The keys that work are tyhg caps lock num lock and maybe a couple others... Ive never spilled anything on the laptop nor have I ever dropped it. I was in love with this laptop for the price I paid for it at Best Buy until the keyboard stopped working on it... It just randomly happened and I'm not sure why. The keys don't appear to stick or anything like that... (normal keystrokes just nothing happens in result of clicking them) I am using a keyboard plugged into it right now... I really need to get this fixed and I'm very upset at the fact it happened just 2 months after the purchase... So that cancels out my bestbuy 1 month warranty right there. I really can't deal with this much longer considering the fact that I was planning to use this laptop for my work.. If I can't get a simple easy fix I will have to find something new somewhere else... sorry to say. Praying for an easy solution/fix.

A:My lenovo ideapad G570 some keys are not working

hi vickydy,
 
Welcome to Lenovo Community Forums!
 
    First make sure this is a hardware concern.
Run an Onscreen Keyboard, by Pressing (Windows key + R) then type in OSK then hit enter
   Now on your onscreen Keyboard click on the keys that are not working see if they responding with the Onscreen keyboard.
     If the keys responded using the Onscreen Keyboard, Then your Keyboard hardware is bad.
Either you call Technical Support to have them repair the unit in / out of warranty repair OR Ask them where to get the part for it and have the keyboard replaced.
 
Hope this helps
Cheers!

Hi Guys,

I am a member of the sevenforums and currently have a win8 laptop so thought I'd sign up here (seems to be the same people behind both forums).

I'm having a little trouble and would really appreciate some feedback.

My Lenovo ideapad z500 had 2 keys (K and I) that stopped working (they worked on the touchscreen) and then after that the delete, 8, and arrow keys topped working. Not sure why.

Before I get the keyboard replaced I'm wondering if it could be something else? There's no water damage and I haven't dropped it so I'm confused. I was told it has to be water damage but maybe 1 drop from the condensation on a glass of water is all I can think that may have affected it.

Would be great for some input on this issue.

Thanks!

A:Laptop Keys Stopped working - Lenovo Ideapad Z500 Win8

I was told it has to be water damage



Not true. In fact, water in the keyboard normally does not cause permanent damage. That is, once the water dries, all works again - most of the time. But that does depend on many variables - type of keyboard membrane, how much water, if just water (no sugars or cream, for example), and how much dust, dirt, oily hair/dander, cigarette smoke, cookie crumbs, etc. are under the keys when the water was spilled. The greater damage generally comes when the water works it way through the keyboard and into the computer's electronics.

I would try a regular PC keyboard first to see what happens. If all the keys work properly with a standard USB keyboard, then you can be pretty certain it is the notebook keyboard at fault, and not something more serious.

I also reinstalled windows 10 on the same system but on that the display starts to fickle as soon as i install the drivers for display.(That i think is some driver issue from lenovo as earlier it was working fine) so finally decided to install windows 7 on the system.
when i start installing windows 7 on the very begining of the installation it says (netstat:windows can not find a network adapter /network drivers )
So can anybody help me in this regard that which are the drivers i should use during the installation and where to find them as these drivers are the installation drivers not the simple .exe drivers.

Which drive can i use to finish this installation?What is the make and model of the SSD that you have installed? By the way, do you realise that Microsoft have refused to provide any updates for Windows 7 on systems that have Kaby Lake processors?  Your 510-15IKB has a Kaby Lake processor, so no Windows 7 updates, ever!  I think that you will have difficulty with the Intel drivers too -- they will refuse to install.  I recollect someone fixing that by editing the INF file to fool the system into thinking that the driver is compatible.  I don't remember where I read that, so you will have to search for the details. If you are a small business and you need to use Windows 7 because of a business-critical app that does not work on Windows 10, you should sell your Kaby Lake laptop and buy a laptop that uses the previous generation processor, which is Sky Lake (e.g. a 510-15ISK).  Microsoft are continuing to offer Windows 7 updates for Sky Lake systems (until support ends in 2020). -- from CyberSimian in the UK

I installed Windows 7 x64 on my Ideapad 700-15ISK, installed all drivers downloaded from the support page but for some reason cannot get wi-fi to work. I see it in device manager (no exclamation marks anywhere), the network interface is not disabled, and yet I cannot search for any wireless networks. I am assuming that the wi-fi interface is actually hard-disabled (via the FN keys; looking at Windows Mobility Center seems to confirm this because it says "wireless off" and the "turn on" button is greyed out and disabled) but I cannot find a way to re-enable it. This article tells you how to re-enable it, but in my case nothing happens when I press FN+F5 (Lenovo utility is of course installed):https://support.lenovo.com/hr/en/documents/ht072689 I'm presuming this is because I don't have Energy Management installed since I cannot find it anywhere (it's not on the support page for the laptop). Can anyone push me in the right direction? Does anyone else have a similar problem? EDIT: the laptop has Intel wi-fi if that matters

Hi every oneI have recently installed windows 10 on my Lenovo ideapad Z580. My laptop's alt, Esc and F4 keys stopped working. I had have the same issue last year but it solved by itself. Honestly I forget what I did last year to solve this problem. I had googled the problem and searched lots of forums and websites but most of users had this problem because their F4 key is combination of Fn and F4. In my case my F4 is not Combined by Fn keys.I check my keyboard in the keyboard tester website and it seems the keys that I mentioned do not work there. The thing is I had this issue last year and I had checked my keyboard by a keyboard remapper namedSharpKeys to notice if it had a hardware issue and the keys ( alt, F4 and Esc ) did not work there too But it repaired by some work that I did and I forgot. I had updated all of my drivers and I updated the BIOS before. But I checked for newer version of BIOS.
