XTG,
I ran into this same issue when I first started using NoteM. It's not a problem, per se, but merely how you have your Advanced Power Settings set in the PPC OS.
Here's what will likely fix this issue for you:
1) Click on Start -> Settings -> System -> Power -> Advanced
2) Under the "On Battery" section, either
- A) uncheck the "Turn off device..." box, or
B) change the time to the longest duration you want to allow your PPC to continue running on battery power without tapping the screen.
When I use NoteM for long recordings, I usually use option A).
Hope this helps! :approve:
