Lenovo Yoga 700 Keyboard and Touchpad Not Working

I have a Lenovo Yoga 700 14ISK (ideapad) with Windows 10 64bit, whose keyboard and touchpad are refusing to work.

Everything else seems to be running smoothly except for these. I initially was getting by via the on screen keyboard until I began borrowing an external wireless one.

 

The following is what I know

  1. Reset to factory settings did not work.
  2. Optimizing OS in BIOS is enabled already (enabling this was suggested by Lenovo Support)
  3. THE ARROW KEYS WORK IN BIOS (??!???!?)
  4. An external keyboard works (I have used two different Logitech keyboards and both work)
  5. Before I sign in, FN+Space seems to work thus (re)activating my backlight. Once I sign in, it stops working.
  6. There's no updates for the keyboard driver.
  7. I have already tried to uninstall the driver, restart the laptop, and allow it to reinstall the driver.
  8. Disabling ymc did not help.
  9. F6 does not re-enable the touchpad.
  10. I tried a couple button combinations I've seen around for people disabling/enabling keyboards, but none worked. (Willing to try more though!!!)

 

Any ideas? I thought it may be a hardware problem, but since the arrow keys work in BIOS; I'm not confident that this is the case.

I have the same problem and also followed the same steps with identical result. It happened suddenly, just stopped working.

Re: Lenovo Yoga 700 Keyboard and Touchpad Not Working

I ended up draining the battery completely to zero a few times and it started working! I later realized that the hard shut down leading to dead keyboard was only after charging it.

 

List of what I did:

  • let battery drain overnight: didn't work
  • let battery drain while I was away: didn't work (both times I believe it didn't fully drain)
  • drained battery until it shut itself down, then turned it back on forcing it to drain all the way to 0% (I played music for a while)

Tadah! I turned it back on after charging it and it was working again!

 

At some point there was another hard shut down after I plugged the laptop in to charge. I drained the battery again, and that fixed the problem: again.

 

I bought a new charger and so far haven't had any further problems Smiley Happy
