The difficulty here is caused by the fact that you used the word "device" instead of "system". You wrote "... should not bring the device out of that mode", with the word "device" referring back to "a mobile device" -- which is the entire system. That is, we have the mobile system and we have the keypad device; calling the mobile system a "device" leads to confusion. > The device is still running, playing your favorite > song collection for example.

Then I can't answer this question without knowing more about how the keypad works. Does suspending the keypad truly put it in low-power mode? What happens if a key is pressed while the keypad is suspended? Do you want to prevent all the keys from working or just some of them? How would the user un-suspend the keypad if the system no longer responds to keystrokes?
