The company I work for sells a kiosk-like device that we are in the process of porting to Windows 8 Embedded from Windows 7 Embedded and to the Dell Latitude 10 hardware platform.
In power-sensitive (aka battery powered) hardware in the past we have turned off the display to conserve power after a period of inactivity. In the background we have to maintain sessions, communicate with other systems, completely shut off the system, and
possibly even turn the screen back on.
However, with DAM, the process that does all of this is essentially being put to sleep as soon as the monitor is turned off. How can we either:
Turn off the screen without DAM being activated, at least for a configurable period of time
Disable DAM for a specific process
Disable DAM for the entire system
I've seen the tips about running "sc config dam start=disabled" but as many others have observed, this does not fix the problem.
Particularly for embedded applications this seems like a major oversight. I know for my needs, we like the form factor of the Tablet, we aren't actually as concerned about battery life as standard consumer use of the Tablet would be.
