Keyboard doesn't respond after pressing Caps Lock.

Keyboard works normally until pressing the Caps Lock button. Hitting Caps Lock will make the keyboard unresponsive, you won't be able to type anything after. Can't even open up on-screen keyboard to turn off Caps Lock since it (on-screen keyboard) will hang on startup. Right now, it looks like restarting is the only way to bring back the keyboard.

Really confused what the problem is. And my Google searches aren't pulling up this specific problem.

I should add that ONE key does respond after pressing the Caps Lock key: the Fn or Function key types the number one (1.) Aside from that, nothing else works.

And it looks like opening the on-screen keyboard and turning on Caps Lock on it works normally. No keyboard hangups. No issues with turning on/off Caps Lock.

Problem is when Caps Lock key is actually turned ON using the keyboard. That's when everything stops responding. Even the on-screen keyboard stops responding though it's working beforehand.

Update (08/19/2020)

It looks like there are other people who run into the same problem. For the newcomers (welcome to the club) and for the sake of visibility, here are possible solutions compiled from other messages in this thread:

A. Disable the Caps Lock key using a reputable keyboard software found online.

B. Disconnect all keyboard connections (and maybe all other connections as well) and put it back together.

C. Replace the laptop keyboard.

As I am inexperienced in opening up laptops, I went with option A. But I would suggest option B if you know how to. Another user has experienced the same problem and reconnecting all the, well, connections is what solved it for him.

Good luck!

Hi Jarell,

This really is a strange problem, first time I am hearing about this too. Let's quickly do some troubleshooting.

Firstly are you running windows, if you do, lets open Device Manager by pressing Windows button + R to open the run box, then type devmgmt.msc. Go down to Keyboards right-click on each driver under the Keyboard section and click uninstall. Reboot the computer and see if the problem continues.

If the problem does continue, plug in a normal USB keyboard and repeat the steps, if nothing happens and everything works 100%, the problem might be the laptop keyboard. I suggest taking it to the nearest computer repair store to be replaced.

If you want to replace it yourself I have attached a link to the keyboard via Amazon https://www.amazon.com/Lenovo-Ideapad-S2...

Hope this helps and let me know if you come right

Ewald

Hey there,

Just uninstalled the keyboard driver and then restarted. Problem persists. But hear this, the same thing happens on an external keyboard. Pressing Caps Lock on the external also stops both external and built-in keyboard from responding. Which makes me think it's a software issue. But on the other hand, you can turn off Caps Lock from the external keyboard but not from the built-in one.

Edit: I was wrong. Pressing Caps Lock on the external keyboard stops ONLY the built-in keyboard from responding.

It does sound like the built-on keyboard is faulty or defective (with the caps lock problem) best is to change it. If the laptop is still under warranty, contact Lenovo for assistance for they will exchange and repair it for free.

I've never heard of this ever either. You could try doing a fresh install of windows, but you would lose all your data unless you backed it up. I also don't think laptop keyboards don't cost much. And if it still is under warranty, you can get I replaced and fixed for free.

I guess I'll try reinstalling Windows first. If that doesn't work, we'll probably send it to get it fixed. I'll do my best to get back here afterwards.

Thanks, guys!

P.S. Still open to other suggestions.

Awesome, hope the Windows reinstall fixes it, best of luck and let us know if you came right.

My computer is Thinkpad X220t.

However, I have the same problem: when the Caps Lock key is off, everything works fine. When the Caps Lock is on and the led is lit, the system starts behaving erratically. Some windows freeze, other keys render wrong characters (ex euro E), etc.

I'm using Ubuntu Linux.

I suspect this problem is generated by a short circuit on the keyboard. Before ordering a new keyboard, I was wondering if you solved the problem and how (software, keyboard replacement or motherboard keyboard connector problem?) . I would appreciate a quick answer.

Many thanks.

Hello. I suggest reading the comment thread under my question. Another user had the same problem and solved it by disconnecting and reconnecting all wires.

As for me, I just disabled the Caps Lock key using a keyboard software I found online.

Best of luck!

I'm going to assume you have already solved your issue. Since it has been a while after you posted this message. But for the sake of other people reading this, these are the possible solutions:

A. Disable the Caps Lock key using a reputable keyboard software found online.

B. Disconnect all keyboard connections (and maybe all other connections as well) and put it back together.

I have a very similar problem. It came out if nowhere and I was not doing anything weird with my laptop. I'm using a Lenovo Legion Y530-15ICH

When the problem first came out my first reaction was to reformat my laptop. But the problem still persisted afterwards. My first reaction was that it's a hardware problem

But after pressing caps lock. My laptop spams the number 6. A weird thing that I noticed was that even if I use the on screen keyboard on Windows 10 tablet mode it reacts the same way, and if I turn off caps lock on the on screen keyboard the physical keyboard work normally again.

Because of this, I think this might be a software/virus issue.

If I figure it out I'll post an update.

I did everything I could and i even prayed to the Gods. I'm an IT graduate so I do have decent knowledge with the these things but in the end of they day it's a hardware problem.

I had my hopes cause if the on screen keyboard

But maybe there's a hardware connection between the two, like it routes it through the device keyboard, idk

I ended up just ordering a replacement keyboard from China online.

Funny thing is my warranty literally expires tomorrow but I live far away from where I bought it. So funny coincidence or conspiracy? hahah

I'm gonna go back to Acer for my next gaming laptop, they last me years. This Lenovo is exactly a year old :(

I wish it was a software problem with the virus problem but it is not. Unfortunately you’re going to need to replace the keyboard because it is a short Unfortunately replacing the keyboard is one of the most difficult procedures procedures you can have on this computer. That said it is possible. Search YouTube for the procedure and the part should run you about $70.

I have just had to change my keyboard and it worked. Cost me about $27. My laptop is HP Pavilion DV6. I have used it for over 7 years and I bought it second hand. I think it's just some short circuit problem from long-term wear and tear.
