BIOS on lenovo y570 for the windows 8

Now I have installed this version 47CN32WW(2.10) of bios! I think this BIOS not fully compateble for the Windows 8 and not all options include for dual graphics! When the new version of BIOS for my laptop is coming with full compatibility and functionality?

I have windows 8 on y570 with 2.10 BIOS and I don't have any problems at all. So... Are there any real problems with your laptop or it's all about "I think"?

I really need the option on the BIOS which can off my intel HD graphics at all and use only nvidia discrete graphics!

This option can't be implemented because of the nvidia optimus technology physical realization. It's because nvidia graphics card outputs all the data via intel hd3000 frame buffer. Moreover, there is actually a way to disable IGP if you use an unlocked unofficial bios, but everyone who tried it got the laptop with non-working graphics Smiley Happy (which is kinda logical, if you think about it). Also, I'm really curious why do you need gt555m always turned on; based on my everyday experience I can say that hd3000 is good enough for all (including video players) but games/heavy graphics applications, which you can easily launch via context menu, if it's not launched automatically. If you need gt555m for linux, then you can search for so-called "bumblebee" project or wait until nvidia makes it's drivers for linux (AFAIK, they promised to do it), and there's no known way to enable optimus-based discrete GPU in mac os x.

Sadly, the option to only use the Nvidia GPU is only available to the Thinkpad line. Both Ideapad and Thinkpad support switchable graphics, but the Thinkpad's bios has the option to run on the Nvidia graphics permanently. You just have to wait for Nvidia to provide drivers that fixes your issue.

You say that the nvidia problem, nvidia say that manufacturer of my laptop (Lenovo) and support of game L2 says that is problem of my BIOS again Lenovo! And no one wont to solve this problem! It's so called "TROLLING" or I mistaken?

Well, I played l2 on my y570, it used nvidia graphics card and I had no problems at all. So, it looks like you're doing something wrong. Go to nvidia control panel->manage 3d settings->program settings, select l2 in the list and check whether it's set to run on discrete GPU. That's all. Also, check whether optimus switch is on.
