Running on battery, if I press the power button and click on "Suspend" the power LED remains green and flickers a little, presumably indicating disk access.
Running on a power adapter, the power LED turns red when I click on "Suspend".
The default Debian MATE OS thinks the battery is always being charged and never recognizes that it's discharging (i.e. running on battery). Could that be part of the problem?
I don't have these problems. I can get into suspend when charging or when on battery, and the battery discharging vs charging status is recognized correctly. (I've updated to the latest kernel, etc, using the update script, so if you haven't, maybe give that a try?) I think I had it happen once where I tried to put it in suspend and it didn't; I retried and it immediately went into suspend, so I figured it was a fluke.
I have a separate issue where the system sometimes locks up while coming out of suspend. (Happens ~20% of the time?) I presume that's a separate software issue, though, and it's not really applicable to my main question.
All I really care about at the moment is being able to configure what wake-up events turn on the system, so I can avoid this issue where the laptop wakes up even though it's closed, and then wastes all its power heating my bag.
