ThinkPad Yoga S1 keyboard unresponsive

Hello,

 

I have a ThinkPad Yoga S1. The keyboard sometimes becomes unresponsive, while the external keyboard still works fine. The keyboard revives after going to sleep mode. I have had this issue since the beginning (2 month ago).

 

The fact that it still works fine with the external keyboard incriminates the driver. But all drivers are up to date. (I made all the updates I could find.) And in the device manager, the status reads « This device is working properly ».

 

Anyone else having the same issue, ... and its solution?

 

Thanks,

JC

Hi Jc-createlli,

 

Welcome to Lenovo Community!

 

As per the query we understood that you are facing issue with keyboard not working when system is on sleep mode on your ThinkPad Yoga S1.

 

Go to device manager and under keyboard adapter uninstall all the adapter and restart the system and check.

 

Run ThinkVantage system update utility and update all the drivers and application from that.

 

Hope this helps.

 

Best regards,

Hemanth Kumar

Re: ThinkPad Yoga S1 keyboard unresponsive

Thanks for your answer. I have to clarify.

 

The built-in keyboard sometimes becomes unresponsive, which actually usually starts by some « wavering » (I mean that the characters I type do not appear immediately on the screen - «wavering» might not be the right word, as I'm not native english-speaking).

 

I work around this either by connecting an external keyboard, or by closing the lid.

  • With an external keyboard, characters I type do immediately appear on the screen, despite the built-in keyboard keeps being unresponsive/wavering.
  • Closing the lid puts the computer to sleep mode, and I get back a functional built-in keyboard when reopening the lid.

 

I executed the procedure as you described, but the problem persists.

Hi Jc-createlli,

 

Thank you for the reply!

 

Perform clean boot option and check restarting the system.

Have you checked booting the system into safe mode?

 

Hope this helps.

 

Best regards,

Hemanth Kumar

Re: ThinkPad Yoga S1 keyboard unresponsive

I ran the PC one hour in Safe Mode, and the keyboard worked fine. But this doesn't really help, as in normal mode, there might be several hours without issue. In Safe mode, the big issue is that I can't really work, as even MS Office 2013 doesn't start.

I'll attempt to muster enough will to try out the clean boot...

Hi Jc-createlli,

 

Ok, also check with updating latest BIOS version?

Re: ThinkPad Yoga S1 keyboard unresponsive

Not yet fixed, but I've noticed that what I initially reported as one problem are actually two.

I initially reported that

  • the keyboard sometimes becomes unresponsive
  • after a few minutes of "text lagging" (i.e. it takes a few seconds for the characters to actually appear while I'm typing).

I realized that the two can happen independently.

During the whole exercise of disabling-enabling services, I focused on the lagging, which proves to be a bad idea, as I've now re-enabled all services, and I didn't spot any services that, once disabled, would avoid the lagging.

I will redo the whole process, this time trying to identify which service should be disabled to prevent the keyboard to become unresponsive.

Hi Jc-createlli,

 

  • I feel that there is some issue with system “Operating System”.
  • Can you check with Linux boot media and if the issue still persist?
  • You can download the application from the below link.

Linux boot media

 

Hope this helps!!!

 

Do post us back if the issue still persists.

 

Best regards,

Hemanth Kumar

Re: ThinkPad Yoga S1 keyboard unresponsive

Hello Jc,

I have been having a very similar issue with my thinkpad S1. It seems that either when my computer runs out of ram or when it recieves a shock, the Keyboard and mouse both stop responding. I can tell because the backlight doesnt even work on the keyboard. 

I tried uninstalling the ultranav driver and using only the synaptics driver for the mouse but the issue would still happen to the keyboard. I haven't found any fix so far other than just putting the computer to sleep and waking it back up.

Re: ThinkPad Yoga S1 keyboard unresponsive

It has been two weeks now without a single problem. It looks like some update fixed the root cause, but I can't tell when nor which.

Thanks for your help all !

Case closed.
