1148739 - navigator.mozPower.powerOff(); doesn't work on real device

Status: RESOLVED DUPLICATE of bug 1148740

(Firefox OS Graveyard :: General, defect)

Description

[aitzol76]

User Agent: Mozilla/5.0 (Windows NT 5.1; rv:36.0) Gecko/20100101 Firefox/36.0
Build ID: 20150320202338

Steps to reproduce:

I'm trying to test an application using "PowerManagement" API, specifically with the "powerOff" method. This API requires "power" permission and "certified" type apps specified in the webapp.manifest file. I also correctly configure my device following this link https://developer.mozilla.org/en-US/docs/Tools/WebIDE 



Actual results:

I want to shutdown my device using this code:
-
var power = navigator.mozPower;
power.powerOff();
-
unfortunately only works on WebIDE simulator and B2G Desktop, not in FFOS 2.0 device. Why my device doesn't turn off? What am I doing wrong?
