Hi,
I have somewhat strange situation.
My 4515s won't boot unless I disable audio in BIOS. And well, if I disable audio in BIOS I have no audio. But then it boot without a problem, and pretty fast. Win 10 x64 is installed, but I don't think that matters really.
Because, before I figure it out what is the problem, I have tried install win 7 x64 and it was the same problem.
And the funny thing is. AUDIO WORKS! I know that because one or two times it has booted with audio enabled and audio worked perfectly.
I think only camera is malfunction. I have tried reflashing BIOS, didn't help, restore BIOS to factory settings didnt helped, removed BIOS battery, didnt help.
So, now I need your help and advice how to boot windows with enabled audio.
Thank you all in advance
