Lenovo is recalling about 13,000 ThinkCentre M70z and M90z desktop computers. About 50,500 were previously recalled in March of 2012.
A defect in an internal component in the power supply can overheat and pose a fire hazard, the firm and the U.S. Consumer Product Safety Commission said in a statement.
Lenovo has received reports of one fire incident and one smoke incident in the United States. No injuries have been reported.
The recalled all-in-one desktop computers, or PCs, are flat-panel monitors with the PC integrated into the monitor housing itself. The power supplies are also inside the monitor or PC housing.
The computer chassis has a matte black finish with the brand name "ThinkCentre" in the lower left hand corner of the monitor front. The recalled desktop model numbers, M90z and M70z, along with the serial number and manufacturing date code can be found on a label on the underside of the unit.
Manufactured in Mexico, the computers were sold: online at Lenovo's websites, by telephone, and by direct sales through Lenovo authorized distributors nationwide from May 2010 through March 2012. The cost was about $500 for the M70z model and $800 for the M90z model.
Consumers should immediately stop using the computers, unplug the power supply, and contact the firm to determine if their computer is included in the recall and to schedule an appointment for a free replacement of the power supply.
Because additional systems and manufacturing dates have been added to the recall, even those customers who contacted Lenovo regarding the March 2012 recall should contact Lenovo again to verify if their system is part of this expanded program.
