Greetings everyone.
please, help assist me with the above PC problem.
The boars number is 6050A2559101-MB-A03. The PC does not recognized HDD, neither does it recognized NGFF SSD.
i discovered that the HDD does not spin.
there were activities at the SATA connection.
Pin 2,3,5,6 rises to 400mv then jump to about 4v, again to mv. It continues in loop that way. Same behaviour at pin 20,21,22.
5v is present at 14,15,16.
Pin 18 which is reserved has about 1.8v, sometimes it increases to 2v+.
Pin 8,9,10 is absent.
Pin 10 being DEVSLP0 is 0. I used to 10k resistor to wake the rail but it was pulled to 0.
theres no short on the motherboard.
I have tried different BIOS setup and rewrite the BIOS chip and EC but no success.
The HDD is still not spinning. The HDD is works elsewhere.
What should I do?
