Lenovo G505 - cant recognise HDD

[quic307]

Hello,
I have problem with lenovo g505 with motherboard LA-9912P, cannot recognise any HDD or SSD.
I guess it's cpu (because control everything in this board).
Does anyone fix this problem?

I attach schematic...

Do you have voltage on pin 8-10 and 14-16? Are R551 and R550 OK?
Check damage on connector and flex cable (if it has got one).

8-10 = 3V
14-16 = 5V

So I guess the problem is cpu...
