Hi guys, so i have 820-00165 with no brain here. Powering on sequince looks like this:
DCIN jack in -> 14second 0.4amp -> restart -> 0.4amp allways on no chime.
Working board looks like this
MagSafe in -> 0.54amps ->0.30amps ->chime
My board bios CS activity: DSCN1077.jpg
Working board CS activity: DSCN1076.jpg
Looks like its only first pulses of bios activity, maybe thoughts what can cause this? Tryed to switch bioses between boards, same thing happens, so we can rule out bad bios. Termination resistors and vias cheked. Do i have bad PCH ?
Piernov, what are your thoughts ?
