I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

Hey there, I found a similar topic but unfortunately, there was not a final response that solved my problem. I own a Yoga 13 Ideapad without the backlight function, unfortunately. Recently I watched a video of a keyboard replacement and I would like to do that with mine in order to replace it with a backlight keyboard. The problem is that I am not sure if my model features the needed connections. The model number is: 219159342273 if that helps.  I found backlight keyboards described as "original" Lenovo parts for about 30?. Is that realistic or fake?Thank you for your help!!!

My keyboard backlight doesn't go on and off automatically anymore depending on how light or how dark it is.  I have discovered this happens since i "upgraded" Lenove Settings to Lenove Vantage. I never gave it much thought because it worked always. Now that it is somehow gone i am experiencing how highly inconvenient this is in my work flow.  There isn't even an option anymore in Lenovo Vantage to enable automatic backlight... Why? I have never heard of 'upgrades' that actually demote an important every day function, and add an inconvenient annoyance.   Please tell me i am missing something, otherwise there is no excuse for this horrible 'upgrade'. Thanks.

My keyboard backlight has stopped working. The hard-drive in my 3-year-old XPS 15 died, so I had it replaced with a new SS drive. My tech reinstalled Windows 10 and I reinstalled all of my software (AutoCad, MS Office, Adobe Acrobat, etc.). Fortunately, I had all my files backed-up to an external hard-drive and restored them to the new SS hard-drive.
I installed Dell Command Update. I open Control Panel, Hardware and Sound, and then Dell Keyboard Backlight Settings.......I can change the timing of the backlight, but cannot change the backlight brightness slider. It is currently set at the lowest setting, but it will not move to a higher setting. So, I do not have any keyboard backlight at all. I suspect that there is a problem elsewhere.....something is not switched on or there is a missing update? I've spent hours trying to chase this down without success. Any ideas? 
Thank You!

A:Keyboard Backlight stopped working XPS 15 L502X

Does the keyboard flash ON when the system is booted (if it does not, you have a hardware problem).
If it DOES flash on at boot time, was the system running windows 10 prior to the drive failure - and if so, did the backlight work?  If it was running an earlier version of Windows, note that Dell isn't supporting Windows 10 on this model - there may not be a driver for the backlight under Windows 10.
If it was running correctly under Windows 10 with the backlight on, have you installed the chipset and other drivers?

I have viewed all the forums and none provided a resolution for this. I could see that the keyboard driver is uptodate. There are no other problems with the keyboard.

Hey all!
 
My keyboard backlight was working fine but then one day it just stopped.
I've pushed f10 and fn + f10 doesn't give any feedback
 
I've gone to the Windows mobility center and made sure things are fine there but still no feedback.
When i push the f10 key the setting in windows mobility center changes but it shows no light on the keyboard

But the CAPS LOCK Light and back light works  
Apart from that nothing else
 
Tried restarting also no feedback from the lights
Also could it have been a recent update that might've caused this?
Is there a driver for this?
 
Please Help

A:Keyboard Backlight Stopped working Dell Inspiron 7000 13

Does the keyboard backlight come on when the system is powered up?  If it does, you may have a software issue.
If it does not, you have a hardware problem.  
First thing to check is that the backlight cable is firmly connected to the system board (this will require removing the keyboard to check).

Check your BIOS settings to see if you can configure backlight illumination there.  And if you haven't already, try Fn+F10 rather than just F10 in case you changed your Function lock so that the F keys act as F keys by default rather than performing the function shown on their icons.

Hi,For your information, almost everyone says it's working by "fn+space" but for my laptop it was "double space", i don't know why.Anyway, backlight was working fine until yesterday. Fan started to get loud so i took my laptop apart and cleaned the fan. The noise is gone but backlight stopped working. Capslock, numlock lights and fn key are working, i do not know if there is a correlation. I read almost every topic about the issue but none of them helped.

Hi, I just bought a ThinkPad Yoga 460 and I have a strange problem. The internal keyboard does not work any more across operating systems, so this isn't software specific. However, the keyboard *does* work in the beginning a cold start until the operating system boots - I can enter the BIOS settings, navigate around there, I can enter the onboard diagnostics utility, everything works fine - until an operating system boots. If I just reboot without turning the computer off, the internal keyboard doesn't work. I even restored factory settings, so I am writing this from an Ubuntu Live USB with an external keyboard until I have figured out how to restore EFI, but the keyboard still isn't working. The problem occured after a long time of using only the external keyboard, so I can't exactly tell what I was doing when it happened. I'm guessing it has to do with the rotation sensor being stuck, but what would be the point of disabling the keyboard if it's physically impossible to press any buttons in tablet mode... Also, the touch pad keeps working anyway. I removed Windows from the laptop and I don't think there'd be an easy way to get it back, so I hope any solutions would work on Linux too. Best regards,Malte

I went into device manager and the usb ports don't show up anymore under the Universal Serial Bus controller tree. The only device that stills works, thankfully, is the charger which plugs into the special usb port. If anyone knows a solution i would be grateful, thank you.

 Hi,  I was a happy user of Lenovo Active Pen 2, but recently it has stopped working. By this, I mean that it does not produce any reaction from the touch screen when I tap the screen with it, although successfully connected to the laptop as the Bluetooth device. I have checked and re-installed the drivers and the software (Lenovo Pen Settings). I have also tried to replace the battery twice, and that seemed a right thing to do, at first: for several seconds after the replacement, the pen was working, indeed. Suddenly, the screen would stop reacting to the pen clicks and touches and would never react anymore. As I mentioned, I have observed the similar behaviour twice.  I would be very glad to get any assistance except for the most obivous advice like "Please double-check the drivers and the device batteries". Thanks a lot.

I purchased a Yoga 2 13 (SN: CB29722715) laptop from US with IWS. Some time back various keys on the laptop stopped working, including Ctrl, 1, 3, 5, and others, making it useless unless you also carry another laptop around. I took it to the repair center in Allahabad, India, but the service center returned it saying that the parts are not available in India. Surely there must be a way to obtain these parts? I've tried to contact Lenovo support on chat and phone, but all they can tell me is to take it to the service center. I finally got in touch with a senior tech support person, who informed via email that the parts required were FRU 25215052 and FRU 25215053, but again, I was informed that these parts were not available with Lenovo (anywhere??) and have not heard anything further since (this was two days ago). Is the IWS completely useless in this case? Is there anything I can do apart from junking the laptop?

Hi fobstaa ,
 
Welcome to the Community Forums.
 
I am also expecting that the keyboard fails to respond in the BIOS too. If cleanup and checking for corroded contacts still have the same issue then replacement of the internal keyboard should be considered.
 
It is probable that the issue is hardware in nature since using different OS shows the same failure but using external keyboard is ok. This can be verified if persistent in the BIOS since it works on basic I/O firmware interface only.
 
Here is the guideline on looking for part number specific to your machine. The support site have documentation tab for the hardware manual as reference to replacement steps.
 
I hope this helps answer your query.
 
Regards
