Never mind... just tested again and it's still happening. Don't know why it was working earlier. I had my lid close event set to blank screen. When I tested and disconnecting the power didn't blank my screen any more, I thought I could safely set my lid close event back to suspend. Now that I have done that, when I disconnect the AC power, my computer suspends. Changed it back to "Blank Screen", and now it's back to blanking the screen when I disconnect AC power. Better than suspending every time, I guess. Grrr... this is frustrating; I thought this bug had finally been fixed, but I can't find the old bug report.
