    ASUS GA401QM dead no lights

    i have this asus laptop. This laptop was bought not working.

    Initially I found corrosion in the 2 attached photo's and after cleaning that with ipa boom it worked

    then it just stopped again.

ID:	3656376 the first 2 mosfets by dc in jack no voltage is passing from drain to source on the first mosfet.

    see circled components on other 2 photo's the circled mosfet has a gate shorted to ground and the other photo that component is shorted to ground

    I'm really not sure where to go from here.

    Well, a good start would be to sort your statements. And to write with at least a somewhat sufficient punctuation, like "dots" and "comma". Because otherwise there is almost no way to understand what you are writing.

    You have shared even 4 pictures and it is still not clear of what you are talking about. Rephrase please.

    Also:

    - Pictures of the initial condition of the affected areas
    - Pictures of the current condition of the affected areas

    The EC area is really looking worse and there would be no words for that if you have seriously tried to power up the device with this mess present. You need to check every single capacitor and every single resistor in this area with help of Boardview/schematics and replace it if necessary. EC need to be replaced too of course.

    Keyboard controller is most likely fried too. You will need a specialised programmer (Vertyanov/SVOD3 or similar) for it.

    Understand that you are in front of TONS OF WORK. Thanks

      As asked, I'm starting this post over again.

      “GA401QM no power no lights”

      Bought this laptop as is. For a project.
      Upon inspection I noticed 2 areas that were affected by corrosion. (See photo's).
      I cleaned the affected areas with ipa. I have included pics of these areas after cleaning.
      After cleaning it did work for a couple days. The battery would not charge and the charging light was constantly blinking.

      Then it just stopped turning on again.
