I had the same problem, but found this BIOS update through the customer service; http://support.lenovo.com/us/en/products...-and-netbooks/lenovo-y-series-laptops/y70-70-touch-notebook-lenovo/downloads/DS100998 It fixed it completely (I wasn't allowed to open it up due to warranty so I never tried that).
