Toshiba PCs not affected by Sony battery issue

Sony is one of the suppliers of battery packs used in some Toshiba notebook PCs. We have investigated with Sony whether those PCs that employ the subject batteries are affected with the same problem that caused the recent recalls issued by Dell and Apple, and have found that the system design and the protection system of Toshiba notebook PCs differ from those of Dell and Apple. We have found no evidence that the problem reported by Dell and Apple in their recalls applies to our notebook PCs. Sony has confirmed to us that there is no such problem as cited in the recalls of Dell and Apple with the battery packs supplied to Toshiba.
