AlarmManager not working when phone is locked

AlarmManager does not start my broadcast receiver when phone is locked for example. I search and try many solutions but none works:

 AlarmManager mgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
      Intent i = new Intent(context, OnAlarmReceiver.class);
      PendingIntent pi=PendingIntent.getBroadcast(context, 0, i, 0);

      mgr.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
                        SystemClock.elapsedRealtime()+60000,
                        PERIOD,
                        pi);

but OnAlarmReceiver is never fired!

I also try with WakeLock:

@Override
    public void onReceive(Context context, Intent intent) {
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
        PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "");
        wl.acquire();
// code
wl.release();
 }

but also not working. why?

It should be. Here is a sample project showing a similar use of AlarmManager that works perfectly fine when the screen is off and the phone is locked. In my sample, the "real work" is done by a WakefulIntentService, by means of a BroadcastReceiver, so the BroadcastReceiver is definitely getting control.
