Waking up

I usually put my QC in standby when I am done, I use it sitting on my desktop. When I come later and press the power button to wake it up about half the time it wakes up and then pops up the shutdown down menu and I have to cancel that. Could the time it takes for that menu to pop up be increased or better yet realize this is a wake press and not a shutdown press? The QC on waking up thinks my finger already on the button is a new press.
