Lenovo is recalling more than 50,000 of its PCs due to a possible fire risk. The ThinkCentre M70z and M90z both house a defective component in their power supplies that can overheat. This is problematic as said power units are embedded within these of all-in-one models. Anyone who picked up one of these 2010 models are advised to call up 855-248-2194 -- Lenovo will setup an appointment to fix the power supply problem. Fire-averse customers can double-check whether their PC is affected at the source below.Lenovo ThinkCe
