I quite often let my computer run, lock the screen and let it download something while I'm away. When I come back, I often forget that my notebook is still running, so I press the key to turn it on.
Before, I had Ubuntu 10.04 (Gnome) which asked me if I want to shutdown when I did this while the computer was still running.
Now, I have Linux Mint 14 (MATE). When I now press the power key while the computer runs, it shuts down. How can I get the same behaviour in MATE that I had before in Gnome?
