Where to look for information regarding the Sony battery pack recall
Sony Corporation has begun a global replacement programme for battery packs containing Sony-manufactured lithium ion cells used by notebook computer manufacturers, in response to concern at recent incidents in which they have overheated.
The fault is caused by microscopic metal particles in the recalled cells which could lead to short-circuiting. Sony said 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 fire. This potential can be affected by variations in the system configurations in different notebook computers.
