2Agenda Calpella Platform Block Diagram. CPU(Clarksfield/Arrandale) & PCH(Ibex Peak-M) & EC(IT8570E) Features Introduce Briefly.N71Ja Power On Sequence Illuminate for Detail.Common Bugs Analyze on N71Ja/Jq.Q & A.
11An Important Component Platform Needed - EC Keyboard matrix/Touchpad controlPower/Charger… etc, LEDs instructFan tachometer controlPower management (sleep/hibernate/wake up/Lid switch)Power sequence control with PCHBattery charger/Cell capacity/Temperature monitorGPIO controlPS: If the system cannot power on, we can snatch LPC_FRAME# to make known that whether EC has worked.
12Power Sequence Provision - ACPI Power State G0/S0:Full onG1/S1:CPU sleep ----PCH 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.
13Power Sequence Types on Notebook Five types of power sequenceG3S5S5S0 (Power on)S0S5 (Power down)S3S0S0S3
14Power on---AC/DC Block Flow Difference:AC mode (plug in adaptor): G3S4/S5 ,have VSUS power. (to save power)DC mode (only plug in battery): G3S4/S5 ,have no VSUS power.

24Common Bugs1.The system can not 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 can not 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 can not 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 sequenceblack screen, show d0~d5 –> memory plug failed or memory brokenblack screen, show F0~F2 –> one DIMM slot failedshow 38 –> check USB port and USB deviceIf not mount LPC debug & New card debug card because of cost down, try to flash BIOS by JIG board or measure sequence.4.The system often show blue screen suddenly in OSun-install drives (even enter safe mode), find whether a device driver installed wrongly cause itun-plug device to checkBIOS updated? Care for BIOS release notecheck FAN status/thermal module –> over temperature?and so on……
25RMA Training RequestHow to judging the CPU’s function when it on board?Debug Card -> Reset -> Power, CLK ->Visual Inspection (Impurities, PIN Broken, curving, Error Component )Do not boot up, How to do?Check Debug codeDebug code:00 -> Reset , Power, CLK , Visual Inspection.Debug code: OK -> GPU, CRT/LVDSThe Voltage and CLK is OK, but no display. How to do?Remove all Device, Check DIMM, Flash EEPROM, Reset COMST, Check all reset nets, Check Debug code.Blue screen, Hung up, How to do?Remove all Device, Check DIMM, Flash EEPROM, Change HDD , Check FAN & Thermal Module, Check Windows error code.The Difference with EC Chip ITE8510、8511、8752 、8512 、8502 、8570.ITE8510、8511 -> SantaRosa platform -> ISA ROMITE8752、8512 -> Montevina platform -> SPI ROMITE8570 -> Calpella platform -> SPI ROM
