  • [SOLVED]820-3476 - Turn on, But


    I Get:
    - Green Light
    - Fan Spin
    - Almost all the Rails

    The PP3V3 is low, like 2v:
    - PP3V3_SO - 2v
    - PP3V3_S0_FET - 2V
    R5360 - 2V
    R5361 - 2V


    The PPVCC_SO_CPU is low to:
    0.53v

    Do you guys have any idea what happen? My humble conclusion is a SMC, but i'm not sure.

              VIN PP3V3_S5 - 3.3v
              VOUT PP3v3_SO_FET = 2v

              and

              P3V3S0_EN - 3.3v

              U8030 is bad?

                Not yet, measure resistance from VOUT to ground, also can apply voltage on VOUT and check if something getting hot.....
