[iBook] Has this happened to your iBook?

[M.Milligan]

I have the white iBook, 1.25GHz.

Where the retaining screw for the battery located on the bottom of the 
iBook, there is a small white plastic ring surrounding the cavity left 
by the retaining screw. This ring chipped off last night and now I 
can't reseat the retaining screw. The battery is in place, but the 
screw won't go back in due to this white plastic ring breaking.

Has this happened to anyone else?

What can be done about it. My iBook is still under warranty, but I 
don't think this will be covered, since it will likely be called 
"abuse". It wasn't.

Any constructive suggestions greatly appreciated. Cheers.
