I have a HP Pavilion DV6-6B55SG. It has two Graphic cards. A integrated Intel HD 3000 and a AMD Raedon 6770M. In the Bios I could just set the Graphics on fixed or dynamic. But I run Mountain Lion on it and it always uses the Intel HD 3000, so i wanted to disable it in the Bios in order to use the 6770M. So 20 minutes ago I wanted to ask you how to flash my Bios to enter the advanced Menu. But I just found out that I need to press F10+A when my Laptop boots. So there was really this Advanced Menu and I entered the Graphics Section, then I changed the Item "integrated Graphics" ( I think) and i put it from enable to disable. There was a item "Primary Display" or something like that and it was on SG, but there were other options like PCI and more. I left it on SG. Then I saved the settings. And now I just have a black Screen. I can't see anything, also when I enter the Bios. Is there any way to reset the settings? I tried to find anything about it in the manual, but there is nothig: tim.id.au/laptops/hp/hp%20pavilion%20dv6.pdf Please help I'm moved to tears, I need it for Collage. The Bios is from Insyde20. Version: F.19 I hope you can help me, thanks for every help
I am not entirely sure this applies to you or model but it should. Shutdown laptop Remove battery and power cord Press and hold power button for 30 seconds this will assist in removing any static in the laptop Connect power cord (leave the battery out of the laptop) Press power button to start computer and whilst it's starting repeatedly tap F10 key this will cause the laptop to enter the BIOS setup In BIOS setup: press F9 key and select "Y" this will "restore defaults" press F10 key and select "Y" this will "save changes and exit". laptop will restart The steps in 6 should be able to be done even if black screen by giving a little time between keystrokes.
Hello redroad and thank you so much for your answer! Unforunately it didn't work like you wrote it but it was the right idea. After your way did not work, I opened my Laptop and put out the RTC Battery for a while. Then I restarted, but again Blackscreen. Then I restarted again and it said there was a CMOS Error and it would reset all settings. And then it worked. Then I looked at the Bios Settings and proved that your way was the right way, but I had to confirm with enter and not y. It always gave me a peep-Tone when I tried to press y. Thank you again so much
Update: I tried your way, when my system was working. Then it would work with enter instead of y. But when I had a blackscreen I tried the way and after pressing a couple of times F10 and then waiting, every key would gave me a peeptone. No matter if enter or any other key. And also my system would not boot if I have a blackscreen. So in general I would hear my Cpu-Fan when it boots but when I have the blackscreen not. What could this be? I just disabled the Internal Graphic Device, why can my system not run without it?
Because the laptop uses the Intel HD card to show you the BIOS & boot screen. The use of ATi Radeon is only in the operating system environment. HP is doing this trick to prolong battery life. The only way I was able to force the operating system (Win7) to use the ATi Radeon was when I installed Ready4GB on Win7 x86 (my laptop has 4GB RAM) while the laptop was plugged in and ATi Radeon was selected from Device Manager. This is due to the fact that there's a bug in the Intel HD driver that won't allow Ready4GB to run. So, the only way to force OS X to use the ATi Radeon GPU is from inside the OS itself - if there are hacks/switches that allow that.
@LatinMcG I have F.19 but there are other versions: h10025.www1.hp.com/ewfrf/wc/previousVersions?softwareitem=ob-112542-1&cc=us&destPage=siteHome&dlc=en&lc=en&os=4063&product=5205521&query=Dv6%206b55eg&sw_lang= But I think the updates just fix something for Windows 8 @ SOCRATE_MMXII Thank you for the information Okay, then I know I can stop messing around with the BIOS and now I know where to try The funny thing is that there is a MacBook with neraly exactly the same hardware as mine: goo.gl/vKCfw It also has 6770M and Intel HD 3000.
