Discussion with APPLE: I have the 3 year service plan so I used it. They recommend NO GLUE. I would think gluing the screen to the frame would make repairs to either, just about impossible to complete. Further, some glues are solvents, hate to dissolve my screen!
My separation now measures 5 mm inch wide when open, and 8 mm wide when opening. Runs 20 cm across bottom.
After talking to Apple Service, the advice is to have it repaired as a cosmetic repair - potential est. is $300, not covered by Apple Service plan nor warranty. They further recommended that I take it directly to a service provider not an Apple Store. Service providers do the work there, stores send it to the service providers. As I use the Ibook in work daily, I have no time/tolerance for delay.
They said that they do not know if continued use of the Ibook in its condition would lead to screen malfunction, but if it did, that the malfunction probably would not be covered due to the original cause being "cosmetic".
Apple needs to take a serious look at this part of their design. I believe it is a design flaw, and if it leads to screen failure, should be covered by Apple. I have a G-3 Titanium, used hard daily for years, and it shows no separation...The question remains: Will the separation of frame at screen base damage things? Will they recognize it as a design flaw and repair them?
