RALEIGH, N.C. – Lenovo and IBM issued a recall for more than 500,000 laptop batteries made by Sony on Thursday.
The recall followed Lenovo’s investigation into a ThinkPad laptop that exploded in flames earlier this month at Los Angeles International Airport.
“These lithium-ion batteries can cause overheating, posing a fire hazard to consumers,” the Consumer Product Safety Commission said in a statement.
Lenovo and IBM, which manufactured ThinkPad laptops before Lenovo acquired IBM’s personal computer business in May of 2005, issued the voluntary recall. The firms worked with the Consumer Product Safety Commission.
Some 526,000 batteries installed in nine various ThinkPad models are involved.
The rechargeable, lithium-ion batteries may pose a fire hazard, the companies said.
Some 168,500 of the batteries were sold in the U.S., according to the Consumer Product Safety Commission.
The Lenovo recall is the fourth involving laptop batters since August. Dell was forced to recall 4.1 million batteries after a series of incidents involving overheating laptops. Apple recalled 1.8 million and Toshiba recalled 340,000. Toshiba cited power loss problems in the batteries. Apple cited fire hazard as the reason for its recall.
Julie Vallese, spokeswoman for the Consumer Product Safety Commission, told The Associated Press that the overheating problem did not appear to be linked to the defects cited in the Apple and Dell cases.
In announcing its investigation last week, Lenovo said that customer safety was its top priority. A Lenovo investigative team arrived in Los Angeles less than 12 hours after the ThinkPad incident. The ThinkPad was taken to a Lenovo lab in Japan for an investigation.
Lenovo issued the following statement:
