1.VL/5VPCU/3VPCU: These power planes will always be turned on unless the AC adapter and battery pack is removed from the system. 5VPCU is the power source of +5V and 5V_S5 and 3VPCU is the power source of +3V, 3VSUS and 3V_S5.

2.VCCRTC: This power plane will always be turned on even when the AC adapter and battery pack is removed form the system. This battery backed up power is used by the RTC module inside the SB460.

3.1.8V_S5/3V_S5/5V_S5: These power plane are used by SB460 Suspend/Resume power plane.

4.3VSUS: These power planes will be stay on even when the system in the Suspend state

5.+1.5V/+1.8V/+3V/+5V: These power plane will be switch off when the system goes into the suspend mode.

6.3V_S5/+5V_S5: This power plane will be stay on in S0 - S4 state and is used by devices that support D3 cold wake up.
