I have a HP Pavilion DV6-6B55SG and it has two Graphics. A integrated Intel HD 3000 and a AMD Raedon 6770M.
I'm running Mountain Lion and it only uses the Intel HD 3000.
It looks like this:
So I read a lot of threads about it, and every thread ended like "there is no solution, until you can disable your onboard graphics".
Well, I figured out how to disable it and this might be interesting for all HP owners.
When you reboot press F10 and when it says Bootmenu is loading press a. Then you will see the advanced boot menu.
My Bios vendor is Insyde and the version is F.19.
The settings look like this:
But when i put "Internal Graphics Device" (Link 3) from Auto to Disable, and then restart I will get a blackscreen and have to do a hard Bios reset, by taking out the RTC Battery
Does anyone know, which settings I need to change?
For example Primary Display. It's on SG (Switchable Graphics), but can be put on PEG, PCI, Auto.
Or is there any other solution for this problem?
Thank you for every help.
