Experiencing some technical issues with my new TensorBook

Thanks for the suggestion. After that change, the GPU now does run on battery power without crashing the system.
But under battery power it’s running at about 1/3 the speed.
(This is measured in training samples processed per second. I’m running NetTrain on Wolfram Mathematica with GPU target).

Experiencing some technical issues with my new TensorBook

I have a brand new Tensorbook shipped with Ubuntu 18.04. It works fine when plugged in. But under battery power, it shuts down almost immediately after starting a GPU job. It works fine under battery power when the GPU is not in use. This issue is not fixed by fully charging the battery.
