What would I do to figure out why Suspend sometimes crashes?

suspend

Something is causing suspend crash occasionally. When it does crash, the system freezes with a black screen and stays on, not suspending. This makes me have to hold the power button until the system shuts down.

One setting difference I have from most people is, I don't use the option that lets you suspend when the laptop lid is closed. So opening and closing the laptop lid has no actions. I like to press suspend manually. Could this preference change be the cause?

How can I start looking for what's causing the crash, since the crash doesn't display errors?
