Hello, was hoping to get some insight on the known design flaw with the iBook logicboard. As we all know, the danish have proven that a fatal design flaw affects the ibook logicboard. http://forums.macrumors.com/showthread.php?t=350024&highlight=ibook+danish after reading the cause of the problem I have avoided turning off my ibook and always have it sleep 24/7. Im pretty sure that having it go to sleep will avoid the fatal logicboard issue but just wanted to make sure or get insight as to the best course of action to avoid the issue. obviously I would like to extend the longevity of my iBook and continue to enjoy using it with out spending more money to keep it "alive". I have already had to have the logicboard replaced once. Will sleeping avoid this "life cycle" problem? Is it safe to sleep without the wear and tear that will eventually lead to this fatal problem? Will apple extend the reimbursement of the cost of replacing the logicboard? Has anyone been successfully reimbursed for their replacement? Thanks!!!
