DP1 (Pebble) Power Sequence Insert AC adapter only, then without press power button Power Plan: PS_ID 0. RTC power plane. 1. Always power plane. 2. SUS power plane. 3. RUN power plane. PS_ID is to confirm that insertion of ACPI Power State: AC adapter 65W or 90W 1. S0: System Full On, All power planes are ON. 2. S3: Suspend to RAM, RUN power off. 3. S4: Suspend to Disk, RTC and Always power ON.(AC) 4. S5: Soft Off, power state like S4. PWR_SRC +RTCSRC is generated by PWR_SRC through D40 +RTCSRC Pin 1 Pin 1 U9 U13 www.kythuatvitinh.com +RTCSRC will be input of MAXIM 1615, then +RTC_PWR is the output of MAXIM 1615 +RTCSRC will be input of MAXIM 1615, then +3.3VRTC is the output of MAXIM 1615 Pin 3 Pin 3 +3.3VRTC +RTC_PWR If no ALW power, what With either LIVE_ON_BATT or should we do? A: Check all ACAV_IN With either LIVE_ON_BATT or ACAV_IN existed, +RTC_PWR can relate circuit. ACAV_IN existed, +3.3VRTC can convert to +5VALW through Q61 convert to +3VALW through Q62 +3VALW +5VALW X7 XTAL 32.768K will oscillate after
