      Hi,I use US15WP and Z510PT.
      System reset is done by  external EC.

       

      Usually,Z510PT starts normally,but sometimes don't; about once every 100 times.
      When investigating,H_CPUPWRGD and H_CPURST of US15WP are still low.
      RESET#,RSTRDY#,SLPRDY#,H_DPSLP# and H_DPRSTP# is High.
      RSTWARN and SLPMODE are low.
      It is observed that Figure 104.Intel SCH Voltage Sequencing of document number 387926.
      What is the cause of this problem?

       

      Thanks.
