2006 Dell is recalling 4.
The company said yesterday that 1 million laptop batteries could catch fire.
The Consumer Product Safety Committee said it would be the biggest safety recall in the history of the consumer electronics industry.
Dell, the world\'s largest PC maker, said,
The ion battery, manufactured by Sony, was installed on a laptop sold on the 18 th of April to July 2004.
The recall raised broader questions about lithium.
Ion batteries for devices such as mobile phones, portable power tools, cameras, digital cameras and MP3 players.
Over the years, the possibility of such batteries catching fire has been acknowledged and has prompted a more limited recall in the past.
But some recent fires involving laptops, including some on the plane, have regained attention.
Dell reported to the security agency that since December, Dell has recorded six incidents of overheating or fire in its notebooks.
None of these incidents resulted in casualties.
Dell said the problems were caused by defects in battery manufacturing made by Sony.
Security agencies say the problems with these batteries are not unique to Dell, which means other companies that use Sony batteries may also have to make a recall.
Sony has sold its batteries to most major computer manufacturers.
The recalled battery is used in 2.
There are 7 million Dell computers sold in the United States, one.
Overseas sales 4 million
During this period, this figure accounted for about 18% of Dell\'s laptop production.
According to the number of batteries still in use, the cost of the recall may exceed $0. 3 billion.
Dell declined to estimate costs, but said the recall would not have a significant impact on its profits.
Sony confirmed yesterday that it was responsible for the company\'s batteries. The company said it would \"financially support\" Dell in the recall.
Dell indicated that affected customers will be notified by mail, online or through the company\'s sales representative and arrangements will be made to send a replacement battery.
At the same time, it recommends that the owner remove the original battery and use the power cord.
In October 2004, the biggest safety recall of consumer electronics involved millions of lithium.
Ion battery of Kyocera mobile phone.
Dell has been plagued by reports of laptop burning in recent months.
On June, at a hotel in Osaka, Japan, a Dell laptop suddenly caught fire during the meeting.
In this case, the analysis shows that the fire may be caused by microscopic metal particles generated during the manufacturing process.
Firefighters at Mount Vernon fell ill on July.
They were summoned to an office at the food processing and packaging company, lilebao, to put out a laptop fire that was enough to burn the table.
In the same month, a Dell notebook parked in the pickup truck cab next to Mead Lake, Nevada, caught fire, lit ammunition in the glove box, and then lit the gas tank.
The truck exploded.
\"A few minutes later, when the laptop exploded, we came out of the canyon,\" said Thomas Falkland, the owner of the computer and truck.
\"Someone will eventually be killed.
\"The battery problem is the latest setback for Dell, which has always been the best on Wall Street.
In the face of more intense competition to force price cuts, the company reported that,than-
Last year\'s expected sales and earnings dropped its share price by more than 40%.
The company is spending $100 million to improve its customer service, which it finds has alienated consumers.
Dell executives hope that the recall, though massive, will prevent further damage to its image.
\"We are ahead on this issue,\" said Alex Gruzen, senior vice president and general manager of the company\'s product group.
\"I don\'t want any further incidents to happen.
\"Other computer manufacturers using Sony batteries were yesterday evaluating similar problems they might face.
Apple spokesman Lynn Fox said, \"We are currently investigating whether the batteries that are provided to Apple for our current and previous laptop lines meet our high standards for battery safety and performance. ” A Hewlett-
A spokesman for Packard said the company\'s laptop would not be affected by the recall because its batteries were specifically designed for its products.
Lenovo spokesman Robert Page said, \"so far, we have not seen any unusual patterns or problems with laptops.
The company says its batteries are designed differently than Dell\'s.
\"Not all laptop batteries are the same . \"Page said. Lithium-
Compared to other types of batteries, ion batteries store more energy in smaller spaces.
They are the cheapest form of battery chemistry and are increasingly used in more types of consumer goods.
