Unlock, please, my Samsung 700G7A intel hd graphics

[Luka]

Hi friends! I need your assistance to unlock the bios option in my Samsung 700g7a.
The problem is in the Radeon graphic - it's corrupted, the strips on the monitor etc.
It needs to be changed or restored, but not in the moment, maybe later.

So I need your help to modify my bios that there be an option to use intel HD3000 videocard only, that Radeon's graphic was switched off.
Or just to modify the bios that laptop could work on the internal videocard only.

At the moment it won't start without discret video. There no switch for it. It's locked in bios.

All your efforts will be rewarded. All the info, backups, dumps in any programs I'm ready to share.
