    Vaio flip 14n ,Missing SLP_S4#

    Board : DA0FI2MB6D0
    i measured 3V and 5V .is ok .
    after press power button, i can see that all voltage present about 0.5 second and after this time ,except 3v and 5v ,all fall to zero.
    i followed this Timing chart and checked all Signals. I noticed that up to SLP_S4#, they are all correct and durable.
    SLP_S4# 0v > 3.3v (about 0.5 Second) > 0v
    I noticed that from this signal onwards, all of them are present only for about half a second and then they become zero.
    In addition, I did not find anything about a short circuit in the board.
    I know that this signal(SLP_S4#) comes from PCH, but if it is not there, what condition causes the loss of this signal? What else would you recommend testing?

    Confirm the voltage to ground on charger IC pu13 for the ACOK and ACIN pins.

      ACIN =3.5 v
      ACOK = 4.7 v

        Good. Check CSSP and CSSN voltage to ground for each.

          Both 18.6 v

            Could you confirm if all the voltage signals are present up to CPUPWRGOOD and PLTRST? (i can see that all voltage present about 0.5 second and after this time ,except 3v and 5v ,all fall to zero)

              measure the resistance to ground of all Gig gray coils, such as PL5, check the resistance to ground of the +5V_S5, and +3V_S5 sides

                With sony, need to look for SHDN#

                  Thx, I measured all coils . All of them are normal.
                  +5V_S5, and +3V_S5 ,These voltages come and go after about 8 seconds.

                    This signal is 4.9 V without change
