I just purchased my first MacBook Pro with 10.7 Lion so please excuse the question as I'm still new to Mac but not a computer newb. I'm currently using my MacBook Pro as a desktop computer using an external monitor with the lid closed as it sits in a stand. Great arrangement actually and works terrific. I've setup Hot Corners for my screen saver with no problems. The problem is, when the screen saver is engaged, my MacBook Pro will go to sleep. I can't seem to find a setting that will keep my MacBook Pro from going to sleep when the screen saver is engaged. I only want my MacBook Pro to go to sleep when I manually set it to go to sleep or when I use it as a laptop and I close the lid. I hope that makes sense. Any suggestions would be helpful and I thank you in advance.
