Volt going to deep sleep?

I'm going to have to try to experiment with this a little, but I had this weird occurrence today when my Volt was charged at home but sitting with the cord plugged in. The car finished charging the previous evening and I had turned off the smart plug, but I didn't get a chance to unplug it. One full day later, I unplug the cord and I forget to unlock the doors. The cord theft alarm didn't go off immediately. 5 hours later, my car alarm goes off and I get the Onstar notification about my cord.

I kind of vaguely remember reading in other threads about how the Volt can go into some sleep mode. It just seems weird that an event like the charge cord alarm doesn't wake it immediately. In all of my previous charge cord alarm cases, the car was actively charging and the alarm went off right away.

If I had not turned off my smart plug, I'm guessing the car would not have gone into the sleep mode and I would have had the alarm go off immediately.

I am smart plug dumb, but I learned from the owners manual that it is recommended to keep the Volt charging when able. I turned to the owners manual after I heard lots of noises like it ate my mama's cooking. She is sweet but a crappy chef. This was going on after being fully charged and even after it has been sitting for days. The manual also suggests to keep the Volt plugged in with temps below 32F or above 90F to maximize the battery life. A nice feature that has prevented degradation in all Volts as compared to other EVs. We have been below 32F for a few days now here in NC. And with 8" of snow I have left the Volt stay put. It is gurgling more than before. So I would keep it powered fully.
