Auto power-off

[Jacob Wall]

What is the auto power-off rules that exist on the Prime? The reason I ask is because I recently forgot to shut off my computer in my office and had the Prime connected to the USB, Connectivity software was not running, and the next morning noticed that the Prime was still on. I had previously also encountered a low battery situation when I first got the calculator when it was not plugged into USB, making me think I had left it on without realizing it, and assuming it would shut down automatically by itself. Is there a setting for this somewhere? I haven't found it looking so far if it exists.

I don't have conclusive tests to prove it happens EVERY time but am leaning towards thinking that there is no auto power-off time limit.
