Yoga 12 trackpoint stops working

2017-02-08, 2:38 AM

The trackpoint on my Yoga 12 frequently stops working. Trackpad and buttons continue to function. I am running the latest drivers.  I just received my machine back from the depot and they just reinstalled Windows 10 and the problem is still occuring.  Whenever it stops I can reinstall the synaptics trackpoint driver and it comes back to life.  Sometimes it is only for a minute other times much longer.  Any ideas?  Thanks in advance.

There is a known issue with the trackpad cable that controls the touchpad and trackpoint. There is a small cable that can get pinched on the bracket of the P-sensor wire as it's not insulated enough that causes an intermittent "recognize, not recognize" of the cable due to a small dent caused by the bracket. 


I'd make sure it's gets replaced or you might lose full functionality of the touchpad/trackpoint if it cuts too deep.

Hope that helps. Sorry you're going through the same issue I am, I've had to fix about 300 of these now at my job, so I know your pain.

TLDR: Thank you very much for your post, Grantlo, it helped me resolve my problem!

Long story:

I had trackpoint/-pad issues on this model almost since i bought it and Lenovo Support wasn't really able to help me back then, so i just accepted that my device had a flaw and that i shouldn't rely on the trackpoint/-pad to work. So i always carried a mouse with me.

Then i read at some point that an underrrated polyfuse could be the reason. Eventually, someone found out that removing the screw in the center of the basecover (which is close to the cable) can resolve the problem. This indeed did work and i was able to trigger the problem afterwards by applying pressure on the center of the base cover.

Now i had a look at this cable and the underlying bracket really damaged the insulation in the center. I guess this could probably have triggered a polyfuse, if power lines were shorted by the bracket, which would explain why people initially blamed the polyfuse.

I now added a few layers of Kapton-tape as insulation and protection on the underside of the cable and the problem really seems to be resolved. At least i was not able to reproduce it again by applying pressure on the respective area on the base cover.

So again, thank you very much for your post and the image.
