Where is the Sleep button?
I checked my computer power settings and I am confounded by one thing: where on earth is the Sleep button? The single button on the front of the machine is the same as every other Dell computer I've owned: a circle with a partial line at the top. According to my Settings page, this is the power button, since it's the only one of the two that gives me the option of shutting down the computer. The sleep button is illustrated as a button the size of the power button, but with a sort-of half moon. So where is it?
