My Keyboard suddenly stopped working while watching youtube videos. The video stopped and the keyboard did not work anymore. Nothing happened when I typed. Also other keys like adjusting volume, toggle backlights etc. didn't work.

I tried rebooting, but after restart it booted me into some kind of Windows-like boot screen or something. It had a blue background, a rectangular shaped light-grey frame and some texts in it. I remember that it had a recovery mode, BIOS and some else stuff mentioned there.

I powered off my laptop. After turning it back on all was good and looking fine.

Today I had the same issue again. Watching a Youtube video it again hanged like that and my keyboard went down. This time I tried to turn off rather than restart, but it just kept hang at turn off so I had to force unpower it anyway. Now I'm telling this here so it's working again, but I'm afraid that this issue could repeat.

My questions:

  • What may cause this issue?
  • How to prevent it repeating/fix it?

The issue repeated the second time already today and I restarted it again. This menu showed up: The menu
This seems to have something to do with my laptop and could be a part of it's ROM, I guess. However, IDK what exactly it is, why the keyboard stops working and all of this happens. I guess one solution would be to completely reinstall my operating system?
Oh, and a note about the videos - when this issues starts, the sound and image of the video seems to unsync. And than the sound gets stuck while video plays and vice versa. It's really weird, for sure.

So after examining closer I noticed:

  • This only happens in browser(Google Chrome) and so far only when watching YouTube videos. Haven't tried other videos or other browser, though.
  • When this happens, my keyboard backlights turns off. The num lock light is on.

System specs:

  • Lenovo IdeaPad Y700 laptop
  • Ubuntu 16.10


  • This so far has only happened in Chrome, Chromium browsers(Firefox not tested) and in Skype(Linux alpha version). No other programs or even games have caused this issue for me this far.


  • It seems that this can happen during use of basicly any program. Yesterday I experienced this issue while making models in Blender 3D.



After request in a comment, here is the output of sudo lshw -sanitize:

  • Well, the computer freeze lasts like 1 second, than it's normal, except that the keyboard doesn't work. Oh, and that's not GRUB menu as GRUB menu has got a purple background for me aswell as smaller letters and fancier font. Oh, and it offers different options than the glitch screen. Unfourtunately, I can't show it as I can't reproduce it. Commented Dec 21, 2016 at 9:14
  • I had a bug that used %100 of CPU when watching youtube. This was overheating the laptop. Have you tried runing top in a console to see what is running when you watch videos?

    Yes, i always prefer bootable iso options to update BIOS, i think that reduces points of failure and also is OS agnostic. PD: @user.dz thanks for the notification.

1 Answer 1


Have Ubuntu 16.04 + latest (as of 2018-March-20) nvidia drivers (don't have laptop at hand - can't tell exact version).

Solved by selecting to use ONLY Discreet GPU (Nvidia only - no switching between Intel HD and Geforce).

So far solved all problems.

  • Selection must be made in BIOS. ( To access BIOS press F2 during boot)
