Hello Everyone,
I am looking for help to identify the problem please.
SSD is not detected. I have checked with different trusted SSD and result is the same.
I get folder with question mark as SSD is not detected. When I try to install macOS is not visible as selection. Power voltage 3.3V (PP3V3_S0_SSD_FLT) is present and voltage on reset line is OK also 3.3V (SSD_RESET_L). The only difference what I notice is 0.64V on line SMC_OOB1_RX_L. I am assuming that can be low because SSD was not installed at the time of taking measurements.
SSD installed is SATA one (not PCI-E).
I hope the problem is not SMC. Can anyone please help to identify the problem ?
Thanking you in advance.
Rafal S.
