If you own a Lenovo ThinkCentre All-In-One computer, you've got a best of times/worst of times dichotomy going on right now: on the plus side, the touchscreen-optimized Windows 8 Consumer Preview probably feels great with the ThinkCentre's multitouch display. On the negative side, there's a chance your PC can catch on fire. Today, Lenovo and the U.S. Consumer Product Safety Commission announced a voluntary recall of over 50,000 Lenovo ThinkCentre M70z and M90z AIOs after determining that a power supply defect can cause the systems to overheat and burst into flame.
Only certain batches of the M70z and M90z are affected, however. Check the bottom of the PC for a label with a date code and serial number: if your date code falls between 1001 to 1012, 1101 to 1112, 001 to 012, or 101 to 112 then there is a chance it could catch fire. If you're affected, stop using the PC, unplug the power cord, and either call Lenovo at (855)248-2194 or visit the web page Lenovo created for the recall. Fortunately, there have been no injuries and only a couple of fire/smoke incidents reported in the U.S., but it's definitely better to be safe than covered in burns.
