Lenovo Recalls LS-15 Power Cords
jones_supa writes US Consumer Product Safety Commission reports that Lenovo is recalling a batch of laptop AC power cords due to fire hazard. The power cords have been bundled with IdeaPad brand B-, G-, S-, U-, V- and Z-series laptop computers and Lenovo brand B-, G- and V-series laptop computers. The recalled power cords are black in color and have the "LS-15" molded mark on the base of the IEC 60320 connector. The company seems to have been bitten by the exact same problem that HP faced this summer. Lenovo has set up an info page for affected customers.
I confess to being a bit baffled at how these power cord defects keep happening. Your basic AC power cord is ancient by the standards of electronic gizmos and by far the simplest thing going into a modern laptop.
recently we had a power cord melt and nearly start a fire in our server room while power maintenance was occurring (so power was only going to 1 PSU instead of both PSUs). Turns out the cables don't meet the appropriate standards (IEC 60950) despite being stamped with "10A".
The cross-section of the copper strands in the failed cable was smaller than that of a 'proper' cable. These cables were illegal, but are being imported from cheap manufacturers in China (obviously without testing to Western standards) and being sold at somewhat reputable stores. Beware of cables marked "PVC YOUZHI DIANXIAN 3x0.75mm2" :)
