Asus A555L doesn't detect any sata device

[Francisco.s]

Asus A555L, motherboard X555LD doesn't detect any sata device.

Original bios is a X555LJ, but I have flashed a X555LD and behaves the same way.

In secure boot menu, the secure boot option is grayed and can't be enabled.

There are no pulses in sata lines. (ie. SATA0_HDD_TX_D or SATA1_ODD_TX_DP)

Boots linux from usb without problems, but not detect any sata either.

Any advice?

Mezzanine connector for daughter board is often a problem.

Thanks piernov, it doesn't work with an adapter (caddy) with a sata disk connected in the dvd slot.

I'm afraid it could be a damaged cpu. (with pch integrated)

Perhaps it's a problem with a resistor or capacitor related to cpu sata circuit.

I only have the boardview, and I think there are no schematic for this motherboard.

Your bios version is X555LJ but what model is printed on the barcode sticker - https://www.badcaps.net/forum/showthread.php?t=96604

Yes I know this conector, it fails in some asus models, but I think this is not the case.

X555LJ is what is printed on the barcode sticker.

I will try anther X555LJ bios from asus website.

Thanks to razor_amd for that good job.
