Hi guys have a HP 14 Labtop. DA0PAHMB8F0 .There is no White LED on the DC Jack .It got a drop of water damage right next to the 3V IC ( Silergy SY8386BRHC) and corroded a resistor and a pad which belongs to the Enable for the IC. I cleaned the area and re-soldered the resistor. Nothing Changed. I don't know what the value for the resistor should be.It measures about 80.0K No schematics available for this model. A good friend on here mon2 helped me identify the IC markings and gave good advice on making sure to measure the input voltages and enables and checking for short.
There is no short on any of the pins of both the 3V/5V ICs.I have 19V present on inputs for the ICs. But no Outputs and no enables for the 3V IC. I only have 1 enable present for the 5V IC.I tried looking for pictures on google for this board to see if i am missing a resistor where the corrosion was found .But pictures are too blurry. Was hoping anyone of you guys may know where the enable for these ICs come from ? And if u may have an idea what value the resistor could be or if i might be missing a resistor ? I will post pictures for reference. I have also ordered replacement ICs for both 3v/5v ICs in case i might need it in the future. But mon2 mentioned to me that before i can conclude a bad IC I must make sure the required voltages are present or not especially the enable voltages.
