Lenovo y720 Keyboard auto typing by itslef

2019-10-08, 14:38 PM

Hi. Purchased this Y720 back in July 2017. I haven’t had any issues with it until the other day. The issue I am having it that the keyboard is stuck just typing on it own. The “CapsLk” stays on or flashes. The laptop just starts typing random numbers, letters, etc. This is becoming a highly frustrating issue as I can barely do anything on the laptop. 


So things that I have tried....

-updating Bios

-updating windows

-keyboard troubleshooter 

-updating keyboard drivers

-uninstalling drivers and reinstalling them 

-sticky keys disabled

-let battery drain to zero and reboot 


All drivers are up to date and the problem is still persisting. I feel as though this is a hardware issue. Any help would be greatly appreciated. Thanks!

Hi MikeSneaks,


Welcome to the Community Forums.


You can try opening CMD. On the black box, you can check if it does the same thing.


Likewise try another external USB keyboard. If the same issue happens on the CMD line and ok with an external keyboard then most likely you may need to have the keyboard replaced specially if cleaning attempts also failed.


I hope this helps answer your query.
