Battery issue with the last PowerBook 15" : a follow up

Since our last news related to battery issue with brand new PowerBook 15", we have received numerous reports from unfortunate users.
What seemed to be initially a small problem, might actually be a larger scale issue. All PB featuring the defect battery model have a manufacturing serial number starting with W8541. But knowing that the battery can also be associated independently to the PB manufacturing number, it can also affect other series.
Apple should start replacing the defect batteries this week.
We still do not know if Apple has also decided to call back models being in stocks in AppleCenters or large resellers.
