The one thing I don't understand is how it went off in class. Did he plug it in? Do classrooms all have plugs for laptops now or did he have to situate himself

The one thing I don't understand is how it went off in class. Did he plug it in? Do classrooms all have plugs for laptops now or did he have to situate himself near one? Alternatively, did he use the battery backup? Wouldn't that mean he set the alarm for during class when it was plugged in and then unplugged it?
