Please verify. Most WiFi cards with AR9285 have AR3011 BT. AR5B95 is AR9285 WiFi only. AR5B195 is AR9285+AR3011.

I don't have your laptop, so I'm not certain on what exactly you changed.

With any major BIOS change, you should repatch DSDT/SSDTs.

Still having this problem... can't find any option in BIOS related to graphics.... I have everything working on this laptop including iMessage and FaceTime kinda sucks I have to restart everytime I wanna use the cam... Even more frustrating that someone with the same model laptop doesn't have the same problem.
Feel like I've tried tweaking everything I could:banghead:

Just to rule it out can you see if your specific webcam is the same as mine in System Profiler? Really wanna get this last thing working. Are you using stock patched dsdt from PBI?

It appears to be a camera manufacturer/firmware issue... the same model laptop can come with a Sunplus (Windows calls it Liteon), Chicony, or Primax. Not sure about the Chicony but the Primax works just fine after sleep. Is this issue still resolvable via some dsdt edit or is it a bigger problem?
 
Just for fun I tried to inject the values of the working Primax cam but still no luck >_> still gone after sleep

Must be some way of signaling it to wake up in dsdt after sleep :(

i changed "Video memory size" from 64 MB to 512 MB

Note : Not 128 , Not 256 ... just 512 MB works for me

i hope you find this options in your bios
 
Damn, mine doesn't have a video memory size. Is your cam vendor also Sunplus in system profiler > usb?
