VPCZ122GX Problem Switching between speed and stamina mode

Hi everyone,

I just bought a Z and it's been awesome so far. The only problem I have encountered is that to switch between speed and stamina mode I need to restart my computer. Unless I'm mistaken, the dynamic hybrid graphics system allows "on the fly" graphics switching without a restart.

Any ideas what might be causing the problem? I apologize in advance if this has already been answered, I couldn't seem to find anything.

Also, my drivers for both Intel and Nvidia are up to date.

Thanks for any help!

 

What do you mean "need" to? when u flick the switch... does anything happen? Also what do you mean the drivers are "up to date"? As in you're using the latest Nvidia/Intel drivers? Or the latest Sony ones?

 

Thanks for the response.

When I flip the switch, say from "stamina" to "speed," the computer simply remains in stamina mode, until I restart my computer. If it is in auto, it will remain in either speed or stamina, whichever was selected when the computer was turned on, until I select the alternative mode and restart.

I've only verified that the Intel and Nvidia drivers are up to date, as I was unaware sony also needed drivers. Could anyone provide me with a link for sony's drivers?
