No really, they can start a fire and I am not speaking metaphorically. Lenovo has extended it’s previous voluntary recall of the M70z and M90z desktops.
A defect within the internal power system which has the potential to overheat and cause a fire has extended to cover an additional 500 units. If you have a M70z or M90z all in one, please visit this page to see if your unit is affected.
All M70z and M90z all-in-one owners are advised to unplug their computers (turning off alone is not recommended) until they have determined that their computer is no longer within the recall batch.
