Hi I currently have a macbook pro (1st gen), a mac mini and a pc. I currently use my macbook pro for emails/calender address book etc and for work on the go at clients, the pc gets used for all my day to day stuff. What I am considering doing is getting rid of my pc completly and just having the laptop. I have a dell 2407fpw lcd hooked up to my pc and I would like to use this on my macbook pro. However the only way I can get to use it is as either a mirror of my main display or in addition to the built in display. I've tried turning it on and shutting the lid but the main display is still selected as on. I think it is related to my sleep issues. If I close the lid the mbp will not go to sleep I have to either go through the menu or use the power button. Any ideas what's causing this? Its just outside warrantee, I've searched for other threads about the sleep issue and tried reseting the power and video units as well as looking for anything running that is keeping it awake. I think it maybe down to the lid switch not detecting that the display is closed? Is this easy/cheap to fix if so?
