When I do the typical shutdown from the start menu it takes forever before it finally goes. I'm assuming this is because all gazzillion drivers and bg programs have to de-initilize. But, when I push the power button on top of the keyboard it goes all most instantly. I'm assuming this is because all it does is set some basic safe guards (like suspending all I/O opperations), and then just terminates the memory. Of course, this is just a theory so I wouldn't be surprised to find out otherwise. Do you know why the computer shuts down so much quicker by the button than it does by the start menu?
