Lenovo is recalling over 50,000 all-in-one desktop PC because of risks of catching fire. The announcement was made in cooperation with the United States Consumer Product Safety Commission (CPSC).

The products being recalled are the ThinkCentre M70z and ThinkCentre M90z, which have been found to have a defective component in the power supply. This part is prone to overheating and poses a fire hazard. Although the recall is voluntary, Lenovo and CPSC advise consumers to stop using the said PCs immediately.

To make sure you possess the defective desktops, take note that all-in-ones feature all of the PC components (including power supply) are housed into the monitor. Both models have a matte black finish with the brand “ThinkCentre” emblazoned on the lower left corner of the monitor’s front. You also need to check the PC’s serial number and manufacturing date code, which can be found on a label posted on the unit’s underside. The list of recalled models and date codes has been published in CPSC’s website. These models were sold in Lenovo’s online store and its authorized distributors between May 2010 and January 2012, with prices ranging from $500 to $800.

There are yet to have injury cases and property losses due to the defective PCs, although the company has received reports of a fire incident and a smoke incident in the US.

In case you have a defective Lenovo all-in-one desktop, stop using the computer, unplug its power supply, and contact Lenovo (855-248-2194 or www.lenovo.com/aiopsurecal) to schedule an appointment for a free replacement of the power supply.
