Power Sequence

1.The system cann’t 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 cann’t 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 cann’t 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

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……

• When we push down the power button but POWER LED not light

or flicker a moment• We can check the ALL_SYSTEM_PWRGD signal.

If the ALL_SYSTEM_PWRGD is low, we can remove those components

location”1、 2、 3、 4、 5” independently . To find the abnormal behavior POWERGOOD and then we can fix the relation circuit.

• IF we push down the power button, PWR LED Keep light but BIOS code:00• then follow the power on sequence detect the abnormal signal and

fix the relation circuit.

ProblemsE-sata device can not be detected.

check the cable plug in correctly.WLAN could not turn on.

Check WLAN switch didn't assemble rightShut down automatically after power on

Check thermal pip and fan assemble correctly or not

ProblemsScreen not display after power on but debug card can run code

Check LVDS cable assemble correctly or not Check LVDS cable is defect
