@micky1979 on your laptop , the brightness maxed ? i mean u are using the full brightness of your screen ? which model of dv6 you have ? why do u think i suffer from that brightness problem ?
So, I have a DV7 6190-SL
I must say that perhaps my screen does not reach the same brightness on Windows, but I have to say it but the difference is small!
From what you tell me, maybe you have a real problem!
Our laptops even if they are DV6 or DV7 6090, 6150, 6190, 6050 etc. even if they have different acronyms, if they have the same bios ... in fact they are virtually identical!
The display, however, can have very different manufacturers, and with very different behaviors! so do not be surprised if it has a problem and no other!
Give me time, I try to do something for you, maybe this weekend ... because I'm really busy (now I'm at work), and I want to see if anyone has a solution ready!
That's sad, i'd really like to switch to osx, would be very nice for my education, anyway benefits of 6770m for some graphics/gaming apps are hodling me off :S really hate hp now for 2 reasons:
1) locked <<<<<<<<<<<<<< bioses(wouldn't be a big deal, if they would have allowed to disable integrated graphics...)
2) warranty service(they didn't send me new hdd as a replacement one, even though they were telling they did ><) @ Denmark
Anyway i'll look more in-depth into all of this from september, now i'm on my vacation ))
btw, you're using osx as your daily os? how's battery compared to windows?
hey eXtremee one question, you run USB 3.0?
For me only work after sleep (but only if I remove charger just put to sleep).
For this problem, I found an IRQ conflict on HPET below:
in ioreg HPET using IRQ as RP04 (USB 3.0), even though I gave it another in dsdt!
My bios version is F.1A, and here's my Extra and DSDT. Thanks a lot!
Try Extras folder included!
Already contains dsdt, if you have one in the root, delete it and lauch Kext Utility!
