Hi, I am running a MacBook4,1 as my main machine. I have it on a griffin stand connected to an external LCD running @ 1680x1050. Now I have searched this forum for an answer but can't find one that actually answers my question, which is: is it SAFE to run the MacBook in clamshell mode? I know MBPs are designed to but I am unable to find any information supporting MBs. I am just concerned about the screen. I use the MB all day at work, and hook it up to the display when I am home. I know that heat no longer dissipates from the keyboard as the old iBooks did. But still I would like to be 100% certain nothing is going to happen running in clamshell. My main uses are the usual: Music/Photo/Web. I also burn DVDs on an external writer. The thing that worries me most is that I do alot of AVI/MPEG to DVD encoding using VisualHub. Any insight would be brilliant. Thanks!
