Lenovo Z710 New BIOS NVIdiA is completely unusable

2014-07-27, 18:38 PM

OK so we all know that there is a new BIOS update for our machines.

F4 problem is now OK.. howerver this new BIOS version is worst!

 

We all know that there were a problem with the grapichs but at least the Nvidia was working..

Now the NVIdiA is completely unusable..

There's no way to make it work now.Only the Intel card is working.

 

Is there someone who can give me a backup of the old 7FCN35WW BIOS version.. because I'm going insane with this lenovo "support"

Is there anyone who updated the latest bios version ?

I've updated and now my Nvidia card is completely not running.

Tried everything and I can't run any game with the dedicated graphic card!

 

Am I the only one ?!

I too am having similar issues.  When I purchased the z710, I had issues with the NVIDIA display drivers.  I used the onboard, updated to Windows 8.1, etc.

 

When I tried to use the NVIDIA, I would get BSOD's, and crashes.

 

Updated to new BIOS, and now the BIOS shows DISCRETE as the only option, the OPTIMUS display setting has been removed.

 

What is the next step for those of us affected by this?

 

Is there anyway to test the NVIDIA?  I tried 3DMark, but it just runs on the Onboard Display Device no matter what I try to do.

What worked for me is throwing away the old PSI Express driver. (Device manager told me that there was an error in there.). After that Windows found the Nvidia card again. Just to be sure you had the same issue as me: You might want to look at my post: http://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/PCI-Express-won-t-load-after-BIOS-update-Ideapad-Z710-00183/m-p/2032495
