Dell and Sony are to share battery recall costs after a small number of Dell customer laptops caught fire as a result of faulty batteries.
Sony made the affected batteries for Dell, and has confirmed it will share the expense of recalling the 4.1m laptop batteries worldwide.
Dell announced the recall of the batteries earlier this week. It said a large range of its Latitude and Inspiron laptops were affected, along with other PC models.
IT managers will now have to decide whether to recall laptop batteries from across their organisations, meaning supposedly mobile workers will have to rely on mains power until battery replacements arrive.
It is not known whether laptops from other manufacturers are affected by the fault, as Sony made similar batteries for other PC manufacturers.
The defect is caused by a short circuit when microscopic metal particles break through the lithium ion cell wall and contact a battery anode. The fault can lead to a simple dead battery or, in the worst case scenario, a fire.
