What is the line resistance PM_PWRBTN#? Voltage on it is understated.
Try to flash with an engineering bios.

From the banal: was the rtc battery thrown off after the firmware before turning it on?
And I don't understand, first signal does not show on IT8572E PM_PWRBTN# , then IT8572E 56 pin pwrbut out sinal go to pch

What RSMRST# ?
When the Power, Bios, Ec are OK, the RSMRST# will go Hi. In the other word, this pin go Low
only when the system reset. If BIOSdata is error, RSMRST# won’t go HI.
When SIO(EC) get +V_RTC the crystal will work.
1. RTC have to be oscillating(32.768KHz).
2. RTCRST# have to be high.
3. RSMRST# have to be inactive (high).
4. PWRBTN# have a trigger.
5. LOW_BAT# have to be inactive (high).

If RSMRST# 0v, there will be no launch, look this way, must be 3.3V,
since the signal is inverse with a sign #.
See also EC RST#.
