I initially voted to close, but have been thinking more about this, and I think the question you've asked may have been missing an important piece of information.

I think what you need to look at are the Windows CE Power Management functions, specifically <a href="http://msdn.microsoft.com/en-us/library/ms920689.aspx" rel="nofollow">SetPowerRequirement</a>. This allows you to indicate that your application is using some device within the system. If not, it's unclear why your application, absent some device interactions, wants to prevent power management from doing its job.

No code needed for this. Go to Start->Settings->Power and uncheck the box next to "Turn off screen if device not used for".

If you tried to do this programmatically, you would be draining the battery power faster than the user intends. That will probably irritate your user.

If your heart is set on doing this, then you can modify the value in <a href="http://msdn.microsoft.com/en-us/library/aa932196.aspx" rel="nofollow">[HKLM]\System\CurrentControlSet\Control\Power\Timeouts</a>

Is your Motorola MC3190 configured to Turn Off if it is running on Battery Power? Will it ever turn off if on External Power?

<img src="https://i.stack.imgur.com/byimv.png" alt="enter image description here">

NOTE: I had to post as answer to show image, but this isn't really an answer.

EDIT: If this is what you are interested in, consider reading the device's <a href="http://msdn.microsoft.com/en-us/library/microsoft.windowsmobile.status.systemstate.aspx" rel="nofollow noreferrer">SystemState</a> property. There are <a href="http://msdn.microsoft.com/en-us/library/microsoft.windowsmobile.status.systemstate_members.aspx" rel="nofollow noreferrer">many members</a> to <a href="http://msdn.microsoft.com/en-us/library/microsoft.windowsmobile.status.systemstate.aspx" rel="nofollow noreferrer">SystemState</a>, and one of them just may be what you are after.

There is no easy technique for what you are wanting to do, because the devices are designed to power down when not in use. If the battery goes dead, the devices have to be completely reset. Make sure this is what you want to do, because there is a reason it is hard to get around.

You'll likely have to register for a <a href="http://msdn.microsoft.com/en-us/library/microsoft.windowsmobile.status.systemstate.powerbatterystate.aspx" rel="nofollow noreferrer">BatteryStrength</a> changed event (like <a href="http://msdn.microsoft.com/en-us/library/microsoft.windowsmobile.status.systemstate.changed.aspx" rel="nofollow noreferrer">>> THIS &lt;&lt;</a>), then try to trick it somehow ...maybe by popping up a dialog box or simulating a key press.

You'll most likely need to P/Invoke some of the lower level coredll.dll functionality (examples <a href="http://msdn.microsoft.com/en-us/library/aa446550.aspx" rel="nofollow noreferrer">>> HERE &lt;&lt;</a>) to get what you want, as this stuff doesn't come wrapped up in the standard WinMobile SDK.

EDIT 2: Here's a Great example that someone wrote to read and control as much of the Power State as possible: <a href="http://www.techlicity.com/blog/dotnetcf-manage-windows-ce-device-power-settings.html" rel="nofollow noreferrer">techlicity blog</a> I liked it so much I've copied the code to a class in my Mobile Project!
