My new Y70 was flickering from the get go (ever 7 to 15 seconds really). Went to lenovo support and requested a call back (took them about one minute to do this). The technician ran the trouble shooting steps and after testing in bios, and safe mode it was determined that a driver of some sort was the issue. The technician performed a recovery procedure (I had the technician take remote control of my computer) and a factory reset solved the problem. This of course is a factory reset so if one goes this route all installed software needs to be reinstalled. However, this solved the problem and the technician said to turn off the automatic driver updates (it updates generic stuff but this machine has some custom ones). All driver updates, get them from the lenovo site for this machine. But no more flickering. Happy machine.
