Hi I am new to this mailing list. I recently purchased a used 550 Tibook. I have some questions if someone can help me. I am using Tiger with the most recent updates. First, I can't seem to get the S- Video out to work. Has that been disabled in OS X or later versions? The second question is I have been reading the discussions at apple.com and there seems to be some sort of issue with the battery charge level and Tiger. Has anyone else experienced this? Thanks for your help, MisterMorse
