Further testing I've found out this happens if both suspend while on AC and hibernate while on battery are set for the same time period. When the laptop suspends while on AC and I later wake it up after unplugging the AC power, the laptop will go in to hibernation. If I play with the touchpad while the laptop is resuming, then hibernation does not occur.
