I have had my iBook for a couple days over 2 weeks and already the left corner I loose and creaks when I type. it gets worse when the iBook gets hot. the right side of the case is also loose but it hangs over the bottom case enough so that it doesn’t rub against the plastic of the lower case and creak. I know there is a another thread on here similar to this one however it unfortunatly doesn’t supply sufficient information. I would like to know if anyone else has had this problem and been able to fix it and how???. iFixit has a replacement upper case for the iBook...I wonder if I have it replaced if it will make the creaking stop??
