Also happens like this:
1. Turn on the laptop on AC
2. Suspend the laptop
3. Unplug from AC
4. Resume the laptop (on battery only)
Then the laptop will lock up (and in my Lenovo Ideapad Z360 the CPU fan is spinning very loud).
The laptop then needs to be powered off, losing all data and corrupting the filesystem in the process. :-(
