Thinkpad P51 Touchpad issue under heavy load

When I tried to run some Deep Learning tasks the temperature goes up and then the touchpad gradually lost response (CPU it running around 40% usage at 3.6GHz and GPU is about 60% usage,  temperature little below 80°C).

 

I have attached the link to the youtube video: https://youtu.be/vTtUf47XuM8

 

It was working fine until around 1:00, then it starts to drift and won't keep up with my finger move, around 2:30min it completely died.

 

After I stopped the task and the temperature went down, the touchpad started to work again. I've tried reboot and reinstall the keyboard driver but no luck. It looks like a hardware issue for me. 

 

I had a W520 for six years and never got a problem. For this one I only had it for 8 months and it's the third time I need to call customer support for a fix( first time keyboard and screen, second time the hinge). I have to say I'm a bit disappointed with the quality control at Lenovo now.
