hi, I've bought ideapad z570 some weeks ago and have troubles with it(since buying) When I switch(using button) to the discrete nvidia video card and launch app(which using 3d graphics), windows 7 freeze and show bsod(driver nvlddmkm.sys, error 0x116). Internal intel video card works great. I found a way(hack ) how to use nvidia card: I switch to nvidia (using button), set maximum performance in lenovo energy management and reboot. After this every games/apps works great. How can I fix it? Thanks. PS: sorry for my english.

Thanks for your workaround! I will try it!
But I do not understand, what is the nvidiausing button?

your link doesn't work
It's not button...I don't know how to name it ... video card switcher on front side of notebook
I just want to know, is this hardware or software bug? Because if this is hardware bug, I'll give laptop in the shop for repairing.

http://forums.nvidia.com/index.php?showtopic=224924 Found solution(maybe), I'll test it later.
To save you the trouble, this didn't work. I did a clean re-install, installed nothing else and the problem still occurs. I can't even go into NVIDIA control panel because even attempting to load the 3D preview in the control panel sends me straight to the blue screen.
I think I'll have to return this laptop...
