    Lenovo G505 - cant recognise HDD

    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?

      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...

The System is out of warranty as it is but does have the option to have it extended.
