I have had the same problem. It does not happen all the time, almost always but occasionally I am surprised. Most often if left alone it will come back to life after some time. Around 15 minutes or so, others regardless of how low it is left it will not and I must take battery out. I have a similar scenario one time and I rolled back an then reinstalled and it fixed some problems but not sure if that'll do here. Maybe I'll try tonight when I get home.
