SYSTEM POWER PLANES
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.

POWER SPECIFICATION
System Power States
ZR3 supports 6 different power states in the system. The SB460 automatically controls the signals required to 
transition the system between the various power states and also informs the PC97551 to control the power planes 
as required. 
The following table describes the different power states switching matrix:
Current StateNext State
Initial ON Standby Suspend Hibernate Soft Off
Initial (1)
ON(S0) (2) (3) (4) (5)
Standby(S1) (6)
Suspend(S3) (7) 
						

							Chapter 143
Mechanical off is a condition where all power except the RTC battery has been removed from the system.
1. Initial to On state: When the AC adapter or Battery pack has been plugged into the system, the PC97551 will 
be reset and initial all output pins then the system goes into Initial state and waiting for power on event. If the 
power button is pressed then the system will go into the ON state.
2. ON to Standby state: The system will go into the Standby state when 963L receives the POS command.
3. ON to Suspend state: The system will go into Suspend state when SB460 receives the S2R command. 
4. ON to Hibernate state: The system will go into Hibernate state when SB460 receives the S2D command.
5. ON to Soft Off state: The system will go into Soft Off state when SB460 receives the Soft off command.
6. Standby to ON state: The system will go into ON state when the system receives any wake up events, for 
example, power button, Lid switch.
7. Suspend to ON state: The system will go into ON state when the power button is pressed.
8. Hibernate to ON state: The system will go into ON state when the power button is pressed.
9. Soft Off to ON state: The system will go into ON state when the power button is pressed.

BIOS Setup Utility
The BIOS Setup Utility is a hardware configuration program built into your computer’s BIOS (Basic Input/Output 
System).
Your computer is already properly configured and optimized, and you do not need to run this utility. However, if you 
encounter configuration problems, you may need to run Setup. Please also refer to Chapter 4 Troubleshooting 
when problem arises.
To activate the BIOS Utility, press 
m during POST (when “Press  to enter Setup” message is prompted on 
the bottom of screen).
Press m to enter setup. The default parameter of F12 Boot Menu is set to “disabled”. If you want to change boot 
device without entering BIOS Setup Utility, please set the parameter to “enabled”. 
Press  during POST to enter multi-boot menu. In this menu, user can change boot device without entering 
BIOS SETUP Utility.
Navigating the BIOS Utility
There are six menu options: Info., Main, System Devices, Security, Boot, and Exit.
Follow these instructions:
