Yoga 720: Keyboad/trackpad/mouse freezes?

I'm having an intermitten problem with my Yoga 720-15lKB (Best Buy Model) Would really love to hear if anyone has experienced anything like it and what might be done about it.

 

Occasionally I get freezes where it won't respond to keyboard, trackpad or (via usb dongle) mouse input, but if anything on screen is playing such as a video it will continue, so I don't think it is GPU related.

 

A quick solution I've found is to close the laptop lid for a few seconds, then re-open it and login from the lock screen, and everything works normally again. Obviously not ideal, but at least I don't have to do a full reboot.

 

Fully updated to Creator's Update and all other Windows updates, latest drivers from the lenovo apps. Lastest BIOS too.

 

Any help would be awesome.

Hello Zulith

Thanks for using the Lenovo forums.


I think this may be due to the creators update, if you have a look on the following site, it appears that your device is not listed (or I`m blind)  in the list of devices tested for the newest update:

https://support.lenovo.com/gb/en/solutions/ht503655

 

I would recommend that you revert back to the previous version of Windows and observe if the issue persists or not.

 

Hope this helps, let us know how you get on.

If the fix were not so fast and easy I would revert... but that is a lot of rollback to do and I like some new features of the Creator's Update. I guess I will patiently wait for more driver updates if that is all that I can do.

The Yoga 720 is a new device and it actually released right around the time of the Creator's Update. This device better get Creator's update certified by Lenovo or it will be the last Lenovo I ever buy!

Thanks for your reply.

Had this problem for 3 weeks. Try different thinks but nothing worked. 

Solved problem finally by installing Lenovo suggested Intel display driver version 21. Windows update had installed Intel display driver version 22. This version 22 display driver is what causes the freeze problem. 
Please go to https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/yoga-series/yoga-720-15ikb/download... (in cause you have my same laptop, if not go to https://support.lenovo.com, click on Downloads and enter the serial number of your laptop) and download the Intel Display driver. Install it, reboot and problem goes away!

How were you able to download version 21? I can't seem to find it in the downloads list no matter what filter critera I apply.

As of around 3 weeks ago version 21 was available in Lenovo web site. It was the only version available. Now Lenovo only has version 22 available. I downloaded it and installed it when it became available 3 weeks and the freeze problem came back. :-| luckily windows allowed me to revert to the previously installed driver (version 21 built on March 2017) and problem went away.

Purchased a Yoga 720 15.6" Feb 2018. Unit locks up once or twice a day after having AC power connected for some time. Discovered that I could return it to normal function by just removing the AC power! I will live with this for now since I don't want to be without it for repair time, hoping some future software update will remedy it.

have the same problem and did try several drivers (incl 21). Problem remains. Only WIN native solves the issue.

WIN native? Are you refering to MS windows plain video driver? If so, the problem with this driver is that it does not allow to change the display brigthness.

Yes, plain MN. And you also can't change the resolution. But better than a freezing mouse pointer
