Laptop Motherboard has THREE Power distribution system :
Acin / ACEDET is important as the voltage sensor for ic voltage charger to pass (adp) Adapter fets current, passed several resistor voltage 19V voltage scaled according to demand charger ic (V.i.R)..
The are standard voltage for sensor each Charger ic .Open datasheet ic charger concerned for more detail .
For more details please see the workings again chager ic / ic battery at the

VALW /Always Voltage The main VALW supply comes from adaptor,Started from DC jack flow to MAIN VALW Circuit.this is a MAIN POWER INSTALATION ON CIRCUIT ,some of using FUSE (F) to safety reason some not.This main power supply circuit using 1 or more P Channel mosfet transistor to maintain stabilized power and distribute power for Charger IC and DC/DC main power supply IC as VCC Power supply.This is important power need to activate that component.Main power also contribute N channel source adapter voltage need processed by the DC / DC main power supply IC (see the datasheet to know how this ic work) produced 3V and 5V_ALW and supply whole 5V and 3V device. if one of this Power missing ,motherboard will not be able to live or referred to the dead .
Before discussing the Power 5V and 3V_ALW should we understand the pathways 19V_ALW . Starting from Jack Power Adaptor sure incoming voltage by a voltage adapter . example is work at 19V~3.2a
Make sure the voltage is present 19V_ALW or (according adapter voltage) for ic charger / Battery ic VCC and for adapter current sensor detector (greater than 2.4V). missing this supply 19V stop by CSIP than 19V blocked by Analog ground coming from charging IC .some other board blocking 19V by closing/opening gate P channel mosfet . Than 19V stop and won't supply to +BAT line and deactivated motherboard 3V and 5V system.
DC / DC main power supply ic and upper /hi N channel (Source )need 19V adapter voltage as VCC power to activated component.

2.VS the Power Switch
VS is voltage that appears after switch on than switch button send a signal through EC_ON# (different board manufacture may have different pin name) to SIO or lately know by EMBEDDED CONTROLLER(EC) .than EC started to regulated signal by given signal gate to powered any device on VS state .
VALW main power suplay standby to get N channel Sources when the signal ( open / close Gate ) transistor to pass voltage through Mosfet ( Drain ) as much as gate requirement than become Source for
VS voltage .
The first one that must be understood is how the system works to enable/disable Power on VS

VS POWER SUPPLY for BOOTSTRAP DEVICE :
There are three BOOTSTRAP device : Processor -Sodim -NB/SB/GPU chip ,each device has a different names of power :
PROCESSOR power name by VCCORE-CPUCORE,SODIM power name by VCCRAM,CHIP power name by VCCP .With out this power the device won't display or not able to load boot up process .
VS for Strap Boot device :
1.Procesor ( VCCORE ) Standard voltage 0.9 VS - 1.5VS

3.Signal
( the wave triger / sensor /2 way confirmation signal / data interface)
Signal function is open / close gate charge of organizing stages enable / disable each component or PCI ( Peripheral commucation interface ) . system signal regulated by Microcontroller where the manufacturer
has made the format settings the form of firmware that is planted into the bios IC to managed embedded
controlling input output system for each ic interface. .
Differences circuit and component arrangement on the motherboard of course require
different settings Microcontroller , so each different motherboard brand and series firmaware will necessarily require different settings .

must be completed is the Microcontroller board system that can be viewed on the

1.VALW / Power Always or MAIN DC POWER SUPPLY CIRCUIT LINE
Power used is DC ( Direct current ) DC voltage in use 19V 3.2A generally but there is also 15V - 20V adapter RANGE voltage used depend on LAPTOP brands.
Power used is DC ( Direct current ) DC voltage in use 19V 3.2A generally but there is also 15V - 20V adapter RANGE voltage used depend on LAPTOP brands.
It better to use motherboard manufacture by using Motherboard code ,we would know how much adapter voltage usage.Clavo motherboard manufacture usually use for 18.5V~3.2a Quanta 19V~3.4a Toshiba(15V-19V) , IBM(16V-19V) Compal-Inventec-Winstron- etc. ) .
VALW also supplying adapter current sensor detector detected by charger IC (see datasheet to know how system charging/discharging work) ,When the charger ic sensor detects current adapter present ACIN~ACDET funcion pin on schema )and confirmed to SIO to manage charging system .
