Reinstall your operating system and only install the actual cards drivers. I don't think its possible to do otherwise. That is to guarantee it never uses your integrated chip instead.

That won't work. The only way to do it is if there is an option in your laptop's BIOS to disable it. Some don't give you the option.

Unless things have changed, it was a solution before.

In that particular example it might have been a driver issue in general but I do remember the idea passed around in other forums previously.

It's impossible to tell from that link whether Optimus was disabled or just started doing what it's supposed to, i.e. taking over when a graphically demanding app is run. The only way to completely disable it for sure is via BIOS.

On my laptop the Nvidia Control Panel lets me choose whether to use the Nvidia graphics or the Intel graphics for select applications or all applications. I'm not sure if this feature is only available for specific Nvidia GPUs, but it's there and works fine with my 650M.
