on wake from suspend, power button is "pressed" leading to hibernation

[Mike Coleman]

On a Dell Inspiron 1420N, running the latest public update of Intrepid, I'm seeing buggy behaviors on wake from suspend. Sometimes it works correctly, but other times it would immediately hibernate while waking from suspend--then I could wake from hibernate and keep going.

While playing with the power settings, I must have changed the "action on power button" setting from hibernate to "ask me". At a later wake from suspend, I actually got the "ask me" dialog, which suggests to me that somehow the power button is being "pressed" (i.e., not by me) on wake, or something else is happening internally that is triggering this. If I cancel the "ask me" dialog, everything is fine. But on at least one occasion I didn't get the chance, either because the dialog is buried, or because it pops up at the last moment and immediately times out (not sure which).

Beyond this, sometimes the wake just fails completely and I end up being booted from scratch. Not sure if that case is connected to the other or something separate.

I'm not sure exactly where to start to try to diagnose all of this. There seem to be many levels of mechanism and I'm not sure even where to start looking.

FWIW, this no longer appears to be happening in the latest release. (However, I did manually edit my "when the power button is pressed" to "do nothing".)
