REMINDER: REPLACE YOUR SONY BATTERY PACK TODAY.
On September 28, 2006 Sony Corporation announced a global replacement
program for certain battery packs that are used in portable computers.
After the announcement by Sony Corporation, Toshiba began participation
in Sony’s global battery pack replacement program and is offering
Toshiba customers free replacement of certain battery packs identified
Recently, certain instances occurred where Sony battery packs
installed in Toshiba portable computers caught fire. Based on our
investigation with Sony, we concluded that the situation was caused by
the Sony Battery Pack. The original Sony Battery Pack had not been
replaced as recommended by Sony and Toshiba. We put importance on the
fact that the incidents that occurred involved unreplaced Sony Battery
Packs, despite of our ongoing replacement program. We will continue to
make every effort to accelerate the replacement of the subject Sony
Battery Packs in our computers.
We strongly recommend that customers participate in the Sony Battery
Pack replacement program as soon as possible.
The subject Sony Battery Packs will be replaced free of charge. This
offer extends only to replacement of the subject Sony Battery Packs, and
does not include replacement of any Toshiba computer.
Safety tips for the customers whose battery packs are
identified as the subject Sony battery packs:
Consult the “Instruction Manual for Safety and Comfort” and comply with
Until the battery pack is replaced, continue to use your Toshiba
portable computer with the original AC adapter power cord supplied with
your computer. Removal of the battery pack until the replacement arrives
is advised. Before removing the battery pack, disconnect the power
source for your Toshiba portable computer and remove the AC adaptor
However, if you do use the battery pack before it is replaced:
- Avoid using the subject Sony Battery Pack with AC adaptor power
- Use your Toshiba portable computer within the recommended
- Do not use your Toshiba portable computer on any surface or
thing that obstructs ventilation of the computer, i.e. sofa, carpet,
bed, or near anything that produces heat.
- When recharging your Toshiba portable computer, do not leave the

Stop Here if You Do Not Have a Matching Computer
If your computer is not among the models listed above, then please
ignore the remainder of this document and any other material regarding
this Sony Battery Pack Voluntary Replacement Program.
If you have a matching computer, the remainder of this document will
explain how to positively determine whether you actually have the
subject battery pack which is eligible for free replacement.
Battery Pack identification
If you own one or more of the Toshiba computer models above, then please
determine whether the subject battery packs are actually installed in
your computer. By far the easiest and most accurate way to make this
determination is with Toshiba's BatteryCheck utility software. The
BatteryCheck utility software will identify whether the subject battery
pack is installed in a Toshiba portable computer. If it finds an
affected battery pack, it will display the notebook and battery pack
identification information. It will also launch your web browser and
open the Toshiba Authorized Service Provider Locator page. Please go to
the nearest Authorized Service Provider to have your battery pack
The BatteryCheck utility software is very small, so it may be downloaded
quickly. Click the following link to download the
BatteryCheck utility software, then run it and follow the simple on-screen
If you do not want to download and use the BatteryCheck utility
software, you may wish to choose to follow the instructions in the
Manual Battery Pack Identification document to visually
determine whether you have a subject battery pack, and to then obtain
the Battery Pack Model Name and Battery Pack Serial Number. This manual
method requires that you remove the battery pack from the computer, and
then visually match identification numbers on the battery pack's
identification label with those listed in the Manual Battery Pack
Identification document. Note that this visual identification may
produce an inaccurate result. It is possible that visual identification
may indicate that the battery pack should be replaced, but the
BatteryCheck utility software indicates that the battery pack does not
need to be replaced. If the results of these two identification methods
do not match, the utility software result (not the visual result) is
accurate. Use of the utility software is the preferred and recommended
method to perform battery pack identification.
