Intel Platform-Calpella Introduction Chini Yang 21.Sep. 2010
Agenda 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.
Calpella Platform Calpella vs. Montevina
Calpella-N71Ja Block Diagram
Calpella CPU Clarksfield(C) vs. Arrandale(A)
An Important Component Platform Needed - EC Keyboard matrix/Touchpad control Power/Charger… etc, LEDs instruct Fan tachometer control Power management (sleep/hibernate/wake up/Lid switch) Power sequence control with PCH Battery charger/Cell capacity/Temperature monitor GPIO control PS: If the system cannot power on, we can snatch LPC_FRAME# to make known that whether EC has worked.
Power Sequence Provision - ACPI Power State G0/S0:Full on G1/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.
Power Sequence Types on Notebook Five types of power sequence G3 S5 S5 S0 (Power on) S0 S5 (Power down) S3 S0 S0 S3
Power on---AC/DC Block Flow Difference: AC mode (plug in adaptor): G3 S4/S5, have VSUS power. (to save power) DC mode (only plug in battery): G3 S4/S5, have no VSUS power.
Common Bugs 1.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 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 & 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 OS un-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……
RMA Training Request How 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 code Debug code:00 -> Reset, Power, CLK, Visual Inspection. Debug code: OK -> GPU, CRT/LVDS The 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 、 ITE8510 、 > SantaRosa platform -> ISA ROM ITE8752 、 > Montevina platform -> SPI ROM ITE8570 -> Calpella platform -> SPI ROM
