Yoga 3 Pro-1370 keyboard problem

My keyboard started not showing key presses on some keys, and strange letters/functions on others.  I used www.keyboardtester.com to discover that all of the keys are acting like the function key is is pressed, even though I am not pressing it.  I tried pressing it hard repeatedly a bunch of times but nothing changed.  I updated the bios, checked that no key filtering is set, no updated keyboard drivers are available, etc.  A USB keyboard works fine.  Is this a hardware issue of a stuck key, and do I just replace the keyboard?

I forgot to mention that the function key is not physically stuck down. It is just acting that way electrically.

I had similar symptoms and replaced the keyboard.

I solved it by re-installing the graphics driver.

Could you please tell me where you got the replacement keyboard from? I have been trying to find one but haven't succeeded yet.

Re: Yoga 3 Pro-1370 keyboard problem

I have a similar problem.  The keyboard works for a few keystrokes, and then stops.  Things I have done to troubleshoot:

  • Updated all drivers 
  • Rebooted, and disabled FastBoot
  • Ordered a new keyboard, installed

Now, in troubleshooting I noticed the problem also exists when I am in BIOS so this is not OS/Driver related.

Is there a good diagnostic I can boot with to see if this is a problem on the motherboard?

I have the exact same problem with the keyboard and the pc stays in Tablet-mode. When did your problem start?

Hi,

 

Did you replace the keyboard yourself or did you have someone else replace it for you? 

 

I purchased my computer recently and this issue appeared on day 2.

Before you replace a keyboard, did you try re-loading the graphics driver?  I have had no problems since I did that last January.

 

For me the problem occured because of the integration between the touch screen and the keyboard and was aggravated when you change orientation of the device.

How did you replace the graphics driver?

 

I also noticed that the problem also came from screen rotations. It is an intermittant problem. 

 

Just today, the WiFi was cutting out too. I keep thinking it may be a material problem with the computer. I am happy to try to replace the drivers, but there doesn't seem to be a self-event way to do that with drivers provided by Lenovo.
