I've found a way to keep the backlight on and the machine from sleeping which seems to work on all versions of Windows desktop and mobile.
Every 9 seconds (as suggested above), do the following:
keybd_event(VK_F24, 0, KEYEVENTF_KEYUP, 0);
This creates a "virtual" keypress (actually a key release) of a non-existant key and fools the system into thinking that the user is doing it.
Seems to work fine on all devices I've tested.
