Give the vendor a timeframe to investigate and resolve. Even sometimes ignores reports like this, at least give them the courtesy instead of expose this as an 0day.
My mistake - I had developed the impression that Lenovo was informed ahead of time. I had only skimmed at first.
I had thought the complaint was about not waiting until what sounds like most of the PC OEMs stopped sitting on their thumbs. Please disregard that part of my response.
