Because my TPF goes up when folding when it does that?I selected turn off display never and it still does it?

I need the display to stay on until I turn the power switch off.

The display wouldn't cause that. The monitor has nothing to do with TPF. You may need to go to Power->System Settings -> Hardware -> Power Management -> On AC Power and change it to not put the computer to sleep.

The only thing that could cause TPF to increase that I can think of is the CPU to be put into power saving or the hard disks to be spun down.

So if you are getting a TPF increase when the screen goes black, that means your actual hardware is being spun down for power saving.

I am running native and I do not see what you asked me to look for all I see is power and in there I have selected to never put computer to sleep just like in display I told it never turn off.
