An important component platform needed---EC
Keyboard matrix/Touchpad control Power/ChargerLEDs instruct Fan tachometer control Power management (sleep/hibernate/wake up/Lid switch) Power sequence control with ICH9M Battery charger/cell capacity/temperature monitor GPIO control PS: If the system cannt power on, we can snatch LPC_FRAME# to make known that whether EC has worked.
ACPI (Advanced Configuration and Power Interface, advanced configuration and power interface) It is by Intel, Unless Microsoft, Phoenix, HP and computer powers that Toshiba make together last specification, it last operating system can Utilize the state of power with various devices of direct management.
Power Sequence Provision---ACPI Power State
G0/S0:Full on G1/S1:CPU sleep ----SB(EXP:ICH9M) has the option to assert the CPUSLP# signal to further reduce processor power consumption. G1/S3:Suspend to RAM ----The system context is maintained in system DRAM, but power is shut off to non-critical circuits. Memory is retained, and refreshes continue. All clocks stop except RTC clock. G1/S4:Suspend to Disk ----The context of the system is maintained on the disk. All power is then shut off to the system except for the logic required to resume.
G2/S5:Soft off ----System context is not maintained. All power is shut off except for the logic required to restart. A full boot is required when waking. G3:Mechanical off ----power failure Because the system does not have any power.

Common Bugs(1) 1.The system cannt be powered on, and the adaptor LED indication flicker.Here is somewhere short, check all power rails whether have been short to GND.
2.The system cannt be powered on, and power LED not lighten.Maybe The BIOS ROM content has been wrecked. +3VA powered? Why not VSUS power? Power IC or MOSFET or Diode burnout?
3.The power LED lighten, but the system cannt bring up to DOS.plug in debug card, view the 80 post code, for example:80 code no motion, show 00 > CPU not work >measure power sequence black screen, show d0~d5 > memory plug failed or memory broken black screen, show F0~F2 > one DIMM slot failed show 38 > check USB port and USB device
If not mount LPC debug & Newcard debug card because of cost down, try to flash BIOS by JIG board or measure sequence.
Common Bugs(2)
4.The system ofen show blue screen suddenly in OSun-install drives (even enter safe mode), find whether a device driver installed wrongly cause it un-plug device to check BIOS updated? Care for BIOS release note check FAN status/thermal module > over temperature? and so on
5.take a software bug on M51A for example in Vista, can use hotkeys Fn+F5 & Fn+F6 to control backlight brightness, but in XP, these hotkeys have no functionVista: report to driver directly to active but XP: need report to BIOS, and it send software SCI to active. solution: update BIOS to 217 or newer version

1.Switching Circuit Debug FlowMOS Visual Inspection InductorResister IC and components around Static Measurement Input/Output Resistance Confirmation MOS Resistance Confirmation Input/output voltage
Power on TestIC VCCENABLE voltage
2.How to make an estimation initially Measure if MOS is short? Visual inspect whether MOS Yes inductorcapacitorIC has any burned symptom Measure if capacitor is short? Measure if IC is damaged? Yes Change damaged component
For the outputMeasure Output Resistance short? YesMeasure MOS to confirm
Maybe L-S MOS is burned
For the inputMaybe H-S MOS is burned Measure 19V input short? Yes Maybe L-S MOS is burned Maybe input capacitor is burned
Measure MOS Measure MOS Change capacitor
PSAll measurement above is static on board
3.How to determine whether MOS is burned?Input/output short is commonly due to MOS shortif it is the case, please measure MOSFET first.
Onboard MOSFET in switching circuit criteria
For high side MOS1.Measure the resistance between Drain and Source, which should be above 50ohm, if so, all high side MOS is considered OK. 2. Measure the resistance between Gate and Source, if it isnt above K magnitude, the MOSFET is considered bad.
For low side MOS1. Measure the resistance between Drain and Source. If not short, all low side MOS is considered OK.
2. Measure the resistance between Gate and Source. If it isnt above K magnitude, the MOSFET is considered bad.
Attentions:1.Please discharge the MOSFET before measurement (mustnt power on) : separately short G and S, G and D, D and S one time. (short G and S is necessary) 2.Measurement sequence: measure D,S or G,D first, G,S last
Summary If MOS G-S, G-D resistance is above 1K ohm ,for high sideMOS D-S above 50ohm or for low side MOS D-S not short, the MOSFET is OK. Resistance measurement sequence: D-S, G-D, G-S Able to use diode level( and D, above 0.1V is OK. The MOS which removed should be confirmed burned or not. If all MOS is changed OK, but output still short, maybe its the problem of IC, or the load device (for Vcore or charger or any other without short pin).1
) 2to measure voltage between S
4.How to determine whether IC is OKIf there is no voltage after power on with all MOS OK, IC is likely damaged. a. Static measurement (suggest step): Remove IC, measure the resistance between every pin of IC and GND (compare with good IC) b. Power on test1 2 3 4

1.Change good IC, check whether output is normal after power on again. 2.If abnormal, check whether the voltage of IC ENABLE and VCC pins is normal (can compare with a good one) . 3. When ENABLE is abnormal, disconnect timing control circuit, check timing control circuit after power on 4.When VCC is abnormal, measure whether the series connected resistors and VCC power rail are OK or not.

LDO circuits include +3VA,+VTT_DDR, +2.5VS,+1.5VS Firstly, measure whether output resistance is short or not . Then power on, measure each PIN voltage. Check whether input VIN, VCC, EN/SHDN# is normal to exclude timing problem. Also can check REFIN/SET/FB. Normally, correct REFIN/SET/FB voltage means IC is OK. Last, change IC to exclude the problem of IC self.

What is MAC Address? Each device connected to a stard LAN needs a Data Link Layer address (or called hardware address), providing a means of unique identification. Each NIC has its unique, hard-coded MAC (Media Access ) address. It is a 48 bits (6 bytes) address written in a hexadecimal format. The first 3 bytes represents for vendor ID the remaining 3 bytes are serial number.

Dual Channel The two channels handle memory-processing more efficiently by utilizing the theoretical bandwidth of the two modules, thus reducing system latencies, the timing delays that inherently occur with one memory module.
Rules to Enable Dual Channel Mode
Matched DIMM configuration in each channel Same Density (128MB, 256MB, 512MB, etc.) Same DRAM technology (128Mb, 256Mb, or 512Mb) Same DRAM bus width (x8 or x16) All either single-sided or dual-sided
DDR2 Electrical Interface Double Data Rate II IC's use 1.8 volt SSTL_18 compatible I/O [class II], how ever the supply voltage may be higher. SSTL-18: Stub Series Terminated Logic for 1.8v [JESD 8-15A]. Class II provides for higher power dissipation, Higher drive and a maximum current of 15.2mA
DDR2 Termination DDR2 modules contain the require resistor termination located on the memory chips using a technique called On-Die Termination [ODT]. While DDR1 modules have the necessary resistive termination located on the motherboard. Using ODT, DDR2 are able to reduce the parts count required for mother board while at the same time locate the terminations closer the the signal destination. The ODT termination can be turned on or off by the DRAM controller. Normally the terminations are turned on for Writes and disable for Reads. The value of the ODT termination is selectable based on the number of modules in the system. With one DIMM module the ODT value is set at 150 ohms [300W pull-up and 300W pull-down]. When two modules are loaded into the system the ODT value is exchanged to 75 ohms [150W pull-up and 150W pull-down] for the DIMM not being written to while the DIMM being accessed has its ODT turned off. Writing to the Extended Mode Register [EMR] controls the ODT presence and value. Three combinations are allowed; termination disabled, 75 ohms, and 150 ohms [ also 50 ohms]. The newest revision adds 50 ohm termination values. ODT improves the eye-structure over SSTL for either Single-Rank or Dual-Rank modules.
DDR 3
DDR 3 DDR3 SDRAM(Double Data Rate Three Synchronous Dynamic Random Access Memory) DDR3 SDRAM improves on DDR2 SDRAM in several significant ways: 1.Higher bandwidth due to increased clock rate 2.Reduced power consumption due to 90nm fabrication technology 3.Pre-fetch buffer is doubled to 8 bits to further increase performance 4.The voltage of DDR3 SDRAM DIMM's was lowered from 1.8V to 1.5V. This reduces power consumption and heat generation, as well as enabling more dense memory configurations for higher capacities.
