Toshiba has posted information about their laptop battery recall, including how to manually identify affected batteries.
You can read the support bulletin here:
– CSD.Toshiba.com (Document ID: 98082281).
It looks like for now, it only affects owners of these laptops:
– Toshiba Satellite A100
– Toshiba Tecra A7
Looks like ultraportable owners are in the clear. Toshiba is actually going to replace around 10,000 batteries, just to be safe, but apparently it only affects around 5,000 or so.
