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). ---------- Добавлено спустя 3 минуты 23 секунды: ---------- LID_SW# ? |

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#. |
