According to Lenovo, the company has received three reports worldwide of batteries overheating and causing damage to fifth-generation Carbon X1 laptops but no reports of fire, injuries, or other property damage associated with those incidents. There were no reports of computers overheating in the U.S. or Canada.

Lenovo has said it will inspect and, if necessary, repair all affected machines free of charge “with minimal delay.” Consumers should stop using computers affected by the recall until they’re repaired. 

The fourth-generation Carbon X1 model, which is recommended in Consumer Reports’ laptop ratings, is not subject to this recall. 

The Details

Devices recalled: The recall involves 14-inch ThinkPad X1 Carbon fifth-generation laptops, which came in both silver and black.

Approximately 78,000 laptops were sold in the U.S. through, CDW, Connection, Insight, Zones, and other PC retailers between December 2016 and November 2017. An additional 5,519 units were sold in Canada.

The problem: Lenovo’s investigation determined that a small screw, left unfastened in the unit during manufacturing, could damage the surface of the lithium-ion battery and cause a short, leading to rapid cell discharge of the battery and the risk of fire.

The fix: To help consumers determine whether a laptop is included in the recall, Lenovo has placed a search tool on its website. You simply select the machine type and enter the serial number.

The illustrations below show you how to find that information—as well as the date of manufacture—on stickers affixed to the bottom of the laptop. The affected computers will have a machine type of 20HQ, 20HR, 20K3, or 20K4.

The Lenovo website also provides assistance in locating the nearest authorized repair center.
