Im not sure if any of you have acciendtly closed your laptop then opened it to a black screen.(happened a little to many times to me). If it has then i have found a solution to turn off the sleep ability, InsomniaX. Its available here [URL]http://www.macupdate.com/info.php/id/22211[/URL], it give you the ability to disable sleep so you wont accidently restart your laptop anymore.
