I can't hold a tutorial on that but there is Wake On Keyboard, Wake On Interrupt and so on. Not all machines implement these but worth a look.
I like to use my Dell Inspiron laptop as a CPU and use a stand alone keyboard (Corsair) and monitor (Samsung).
The problem that I'm having is that the only way to get the computer out of sleep/hibernation is to pull the laptop out and open it up completely (and I mean not just a little bit but a full 90 degree angle) and hit the power button to make it come on.
There's no "on/off" key on the keyboard and the windows key doesn't seem to work for this. "Esc" also doesn't work.
I'm not sure it's a good idea to make it so that it doesn't turn off at all, so is there another way around this awkwardness?
Thanks in advance.
