help! ideapad 120s keyboard not working

so yesterday afternoon, I was watching a youtube video and realized that the spacebar was no longer functioning as a play/pause button. I then realized that none of the other keys were working other than the power button. I followed the troubleshooting steps here. I did the last step, which seemed to work for a short time, yet when I went to youtube again and used the touchpad to forward the video, the keyboard stopped working again. I went to do step 3 again, but this time, it would continuously enter one letter. I shut down my laptop 3 times, and the same thing happened all 3 times. finally, I let the battery drain and powered it on this morning. the keyboard can no longer be fixed by use of step 3. I am using the on-screen keyboard now which is very time-consuming and which has been working throughout this entire process.

Re: help! ideapad 120s keyboard not working

Hi mgloria,


Welcome to the Community Forums.


Would connecting an external USB keyboard work?


As mentioned on the guide, " If failed keys do not work, the issue should be PC hardware issue with high possiblity" , you may need to call in technical support for the issue.
