Lenovo issued a worldwide recall on lithium-ion batteries from a number of ThinkPad models, saying they pose a fire hazard risk. Lenovo urged customers with a recalled battery to refrain from using it immediately.
“Until a replacement battery arrives, you should turn off the system, remove the battery, and only power your ThinkPad by plugging in the AC adapter and power cord,” the company said.
According to Lenovo, the batteries in question shipped in a number of countries, included in various ThinkPad notebook models between October 2010 and April 2011.
