G570 - switchable graphic [ Edited ]

[forth]

Hallo,

I have little problem, i have Lenovo G570 with AMD HD6370 and i3 processor. But i can't switch graphic from radeon to HD3000. In devices manager i see only HD6370...

All drivers from lenovo, no powerxpress in right click.

I call to Lenovo support, people from support told me that G570 have switchable graphic, but they can't help me with enabling HD3000.

I try Ubuntu Live, i don't see Intel HD Graphics in linux devices manager , only Radeon HD6370. What's wrong?

I conducted an investigation with the help of several tools and G570 bios file, muxless option is enabled (default), but it can not be started, probably because  the design of the motherboard was changed. So I have only HD6370. Not nice things lenovo, you could tell about the change. More details on PM if you want.
