Not sure I'm searching using the correct terms. My question is, how can I extend the time Lion remains open while I'm away from the machine. I seem to be the only one with issues but I find it extremely annoying that walking away to get a coffee (I'm not talking going out to a coffee shop) and coming back to find the machine in sleep(?) mode. Added to the issue, my Lion setup only seems to wake on keyboard, and requires a password, where as my Snow Leopard install just awoke on mouse and no other activity needed.
