    hello,
    i’ve got a dell e3330.
    everything was fine, unless yesterday it got cooked.
    it wont turn on at all.
    when i connect the charger, the Caps lock LED glows for say 3 seconds and then goes off.
    I decidede to take things off and then i noticed that the SCSC was getting hot, even if you place the battery / power supply with out touching the power button.
    I’m here looking for a suggestion/solution for this board.
    My guess is that the Super I/O is fried.
    Please advise.
    Thanks

      if the Super I/O burn you need to replace if you know how to do that, or you need a new motherboard.
      but first you have to know if the super I/O is hot because its work or its very hot because its burn.
      compared to CPU and GPU temperature.

    hello helpmate,
    let me try and explain it to you.
    The Ic will start warming up, once i plug in the AC cord/ put the battery in.
    However, once i press the power button, it starts getting real hot.
    No display/nothing on the LCD.
    Thats the only IC which is getting hot without functioning!!
    Please advise.

      with multimeter check countinuity on SMD capacitor and mosfet beside the IC, the short capacitor or mosfet can make IC get hot, if there is no short capasitor or mosfet, thats mean the IC is burn you need to replaced or you need a new motherboard.

    Hello sir. Can you please let me know if you can give me a link of service manual?
    Also. No other components are heated. Only this super io is heated.
    Thanks
