It appears that this is a common issue with Dell M6500 and 6600 devices. We have few other laptops from Lenovo (thinkpad with NVIDIA 4200M and other nvidia cards). Those seems to working fine. See this thread https://forum.solidworks.com/message...#262573#262573
Tomorrow, I'm gonna try to use device without connected power supply. Otherwise I'm gonna ask dell to replace my card or entire laptop. I can't work like this. I need fix.
