Toshiba said today it would replace about 340,000 laptop computer batteries worldwide in what is the third recall of faulty batteries made by Sony in less than 40 days.
The batteries, used in Dynabook and Dynabook Satellite laptops made between March and May this year, could fail because of problems with storing and transmitting power, a Toshiba spokesman said.
He declined to estimate the cost of the move, saying it would not affect earnings, and would not say whether Toshiba was asking Sony to foot the bill.
The spokesman said that the faulty batteries would not cause fires.
Last month Dell and Apple Computer recalled almost six million Sony-made batteries, saying they could produce smoke and catch fire.
Fujitsu and Hewlett Packard, which also use Sony batteries in their laptops, said no battery problems have been reported in quality control checks.
