Hi guys,
On motherboard ACER AN515-52 type LAF951P.
I fixed issue with not starting computer (it was the PQ201 component not working properly).
But after checking everything I have still an issue with secondary SATA connector JHD1 (for HDD typically).
Basically some HDD spin but are not detected by the bios.
Already tried following:
checked the 4 data lines
#2 RDSATA_PTX_C_DRX_P4 => CO18 (10nF seems OK) => RO24 (0Ohm measured at 0.25Ohms).
#3 RDSATA_PTX_C_DRX_N4 => CO17 (9.68nF seems OK) => RO23 (0Ohm measured at 0.26Ohms).
#5 RDSATA_PRX_C_DTX_N4 => CO14 (10 nF seems OK) => RO22 (0Ohm measured at 0.24Ohms).
#6 RDSATA_PRX_C_DTX_P4 => CO16 (9.68nF seems OK) => RO21 (0Ohm measured at 0.28Ohms).
Changed the connector as the one used was not in very good shape.
Changed the sata cable of course.
Tried 3 HDD some spin and some not (0 are detected in the BIOS).
Resetted the BIOS completely.
Flash backward the BIOS also.
The M.2 SSD is also in SATA mode and AHCI selected.
Both lines are activated in BIOS.
Don't use the RST mode.
Well I think I have made all the test possible, another issue could be a PCH damaged ! (all other functions are working).
Any help will be greatly appreciated.
