  • 820-3115 asd error 33011 fan 100%

    Hey guys,

    i have a fully working 3115. only drama is fan goes 100% few seconds after turn on.
    I checked fan connector and resistors around which all work measure fine.

    When the machine is on and i test for voltages i probe smc_fan_0_tach and the fans go to normal speed. when i let go they ramp up again?
    what causes this issue?

    thanks

    Post the entire error message from ASD (3-4 text lines).
    Set On Error option to Continue and report all errors.
    Usually trackpad board/flex issue.

      Run ASD150 and report what errors it gives you. Run on error as 2informaticos said

        i put new trackpad and it worked. I then ran through usc (because there was some flux on board) and now fan spin is back? Please advise.

          Why do you insist so much with UC???
          Use alcohol and tootbrush to clean flux.

          Now check/clean trackpad connector.
          Also look for knocked off components.
