ACPI Global System Power State

www.maytinhav.com

★G3: Mechanical off. In this state, power supplies on computer have been removed,

but battery.

★S5: Soft off state. In this state, there is standby power, and the system can be

wakening back to the working state, after which the computer will reset

completely.

★S4: Sleeping state. The S4 sleeping state is the lowest power, longest wake latency

sleeping state supported by ACPI. In order to reduce power to a minimum, it

is assumed that the hardware platform has powered off all devices. Platform

context is maintained

★S3: The S3 sleeping state is a low wake latency sleeping state where all system

contexts are lost except system memory. CPU, cache, and chip set context are

lost in this state. Hardware maintains memory context and restores some

CPU and L2 configuration context. Control starts from the processor’s reset

vector after the wake event.

★S2: The S2 sleeping state is a low wake latency sleeping state. This state is similar

to the S1 sleeping state except that the CPU and system cache context is lost

(the OS is responsible for maintaining the caches and CPU context). Control

starts from the processor’s reset vector after the wake event.

★S1: The S1 sleeping state is a low wake latency sleeping state. In this state, no

system context is lost (CPU or chip set) and hardware maintains all system

contexts CPU.

★S0: The S0 state is the system working state.

First compare

client with RMA

test result .

Y

N

Re-test for

re-produce

client result

Y

Visual inspection，check the CMOS JBAT lose or turn

over，check PCB fail with short，open .notice component

void solder，burn missing or wrong. Notice the problem

of IC missing or void solder. EL-capacitor destroyed

（e.g.bump.relex.exe）

To repair

directly

Y

Measure the vcore12V without power

and cpu on by multimeter

Detect and to see the main voltage if

short to the ground

N

Y Find out the reason then try

to solve it

Assemble cpu，fan memory debug

card and so on，press power

button to see the MB and the fan

if work well，also the code

showed on debug code

1. if the board no action after press the

button（the error code is M01in card）the

debug card will not have been shown and the

fan will not running . check the

following ：

（1）check the 3.3V in JFP1 pin8（this

voltage is supplied by vcc_sb），if this

is no problem .Check the circuit

from pin8 of JFP1 to the pin80 of

SIO.

(2) check the CMOS jumper-JBAT1 if

correct.

（3）check the crystal Y5(32.768K)if can

generate check RSMRST# from SB, if

not, check the voltage of pin85(SIO)

is normal, and the relevant circuit

has broken or not.

voltage of Drive from U19(UP7706U8) ok or

not.

Show FF

(1) Try to press the bridge first，seeing if

can finish running.

(2) try to use bios bootable card (TL399

card)，if can boot reflash bios，or change the

bios.

(3)check the starts of signal with measure

power on sequence，refer to power on

sequence.

(4)Check the clock frequency from

CLKGENERATE to CPU, NB, SB. (every

frequency size refer to CLKMAP)
