I never made the connection that it was since I bought the new battery that she had been getting hotter...

Apple Authorized Resellers from October 2003 through August 2006 for
between $900 and $2300. The batteries also were sold separately for about
Chiana's new battery was A1078, 3K526...
So I'm now back to the old battery that doesn't hold a charge very well while I look into getting this one replaced. An ideal situation would be to be able to just take it into an Apple store and walk out with a new one.
