Sony has joined the recall of its own laptop computer batteries, adding its name to the list of laptop manufacturers calling in the batteries as a fire risk.
The company is initially planning to recall 90,000 batteries in Japan and China, with no numbers given so far for recalls elsewhere in the world.
Sony is also considering whether to adjust its full-year results forecast in a move that is understood to be prompted by the huge recall programme and reduced prices for the PlayStation 3 games console.
"We are in the process of deciding whether a revision of full-year earnings is necessary,” the firm said.
Laptop manufacturers have now recalled about eight million Sony lithium-ion batteries after a small number of fires caused by overheating.
The recall programme has led Toshiba, Hitachi and Fujitsu to consider seeking compensation from Sony for damage to the reputation of their brands and lost business.
