Does anyone know of a laptop (brand, model) that can be used only as a processor, with a large desktop monitor, and a larger, external keyboard for desk use? So far, all the ones I have looked at "go to sleep" when you put the laptop lid (screen) down. I don't want the laptop screen up in front of me when I am using the larger desktop monitor. I want to be able to grab the laptop and go at which time I will have the built-in monitor and keyboard when traveling, but can use the laptop strictly as a processor at home. I realize I may have to purchase a docking station to use both the external keyboard and monitor, although I thought that if the laptop has enough USB ports, both of these could hook directly without the use of a docking station. Thanks.
