i) Press Release - Sony to Initiate Grobal Replacement Programme for Notebook
                   Computer Battery Packs

                                                              September 28, 2006

                                                                Sony Corporation

Sony to Initiate Global Replacement Program for Notebook Computer Battery Packs

Sony Corporation will initiate a global replacement program for certain battery
packs that utilize Sony-manufactured lithium ion cells used by notebook computer
manufacturers in order to address concern related to recent over-heating
incidents. Sony always strives to deliver the highest level of satisfaction to
its customers and all consumers. We believe that this program is in the best
interest of both our customers and all consumers.

Sony is discussing this plan with the US Consumer Product Safety Commission and
will coordinate with other government authorities as required. We will announce
details of the program in the near future.

Sony has been supporting the recall of battery packs for Dell and Apple. As we
have previously explained, on rare occasions, microscopic metal particles in the
recalled battery cells may come into contact with other parts of the battery
cell, leading to a possibility of short circuit within the cell. Typically, a
battery pack will simply power off when a cell short circuit occurs. However,
under certain rare conditions an internal short circuit may lead to cell
overheating and potentially flames. The potential for this to occur can be
affected by variations in the system configurations found in different notebook
computers. Sony believes that this engineering analysis remains valid.

Sony will consult with its OEM customers that utilize these battery cells and
work with those that choose to participate regarding quantity and the scheduling
of replacement battery packs.
