Charging Ubiboot handles rtc and usb events to boot up device from power off state: a) to Ubiboot telnet console (when connected to PC USB), device will not be charged. b) to configured default kernel (harmattan) to charge (when connected to wall charger). c) to configured default kernel (harmattan) to trigger alarm. "Case a" works flawlessly. "Case b" sometimes does not work, but reboots and then starts up Ubiboot console/screen (not charging). "Case c" needs some precondition. Make sure you have shutdown your device from Harmattan. Otherwise the alarm may not be triggered in NITDroid or will not be triggered in Nemo.
