I just bought this computer. Despite my repeated attempts to establish a power plan and turn off the switches which require a password to waken, my screen goes to sleep in exactly one minute, shows the screen saver -- a very beautiful shell -- and refuses to let me continue to work unless I type in my long password. This is maddening. I've been on the phone twice with Technical Support. They are very nice, but we are at the point of returning to factory settings. Can anyone help before I have to go through the tedious reloading required?
