I have a Z710 with nVidia card and has exactly the same problem, when I took my notebook to a Lenovo official representative in Qatar they told me that it is an Energy Management software bug. I honestly do not think the same.
What can I do? Does Lenovo USA send power adapter replacements to Qatar? Shouldn't they as Lenovo representatives do the same? (replace the power supply for a 135 watts).
