Intermittent white line while matlab is opened

Hi guys, i have a strange problem. On my new notebook with i5-5200U and gpu nvidia 840M,while i work on matlab there is a intermittent short white line on left edge of display. This is present only when matlab is opened, or Cadence Orcad! I would know if there is a conflict between matlab and nvidia drivers, because with a external monitor the line is avoided.

Thank you all

Did you update the drivers already and which Matlab version are you using?

Yes! I updated the drivers, and i tried with 2013a and 2014b, with Windows 8.1. It's very strange, with AC adapter this don't happen or with external monitor!
