I have the HP laptop m7-k211dx with the black screen problem.
All the voltages are present but no picture.
I have tried the bios 02292 from the link and it works but i get the message at the post that the bios is in the unlock mode.
i cannot lock it in the bios there is no option.
I will post the original bios dump and 02292 version.
Thanks....

Hi guys, I hope you can help me. I'm trying to identify an audio chip on this device, since NVRAM reset, SMC reset and replacing speakers yield no results, I'm pretty sure it's the chip. The sound comes back briefly after sudo killall coreaudiod but it's muffled, as if the speakers are blown, which they are not. Same effect with SMC reset -- the sound comes back briefly, sometimes the chime can be heard, sometimes it's absent.
I have a schematic for the Open Board View, but I can't seem to locate what is usually an audio - U6200 or U6201, what am I doing wrong?
