HP 14-ba094sa x360 schematic and boardview

Hi, can I get a schematic and board view for 14-ba094sa HP x360 convertable. I have a blown component but have no idea what it is and where to find a replacement

I don't have a schematic for this but i think it's a load switch, judging from experience. refer the datasheet below and compare for confirmation.

oh, I have no idea what that is lol
would something like this be suitable?

It has the same pin out so in theory may work as a substitute, assuming that there are no other fault in the board. Since the original part is severely burned, i would highly recommend removing it and checking for short circuits or low resistance in both input and output sides before attempting to replace.

I have a problem with this component which is burnt together with the LCD flat cable.
How can we trace the component? Can it be the same as U4002?

Hi Guys, I have this HP 14-ba094sa x360 that won't display or boot after liquid damage. The board as been thoroughly cleaned from corrosion and residue. It fires up but no display and after a fex seconds the fans goes to full speed. I found this resistor that's getting to temps close to 100 Celcius... Can anyone help identify it so I can replace it please?

The IC in question is G5388 which is specifically designed for generating DDR Memory VDDQ and VTT voltages. I couldn't find a datasheet but pin 9 of this chip is VCC (5V) and the resistor in question is connected to it. I guess it's a low value current limiting resistor connected between the 5v supply and the IC VCC pin (act as a sort of fuse. Generally between 2.2 to 10 ohm). If it's heats, then there should be a short or leak in it's output side for sure. Usually it will be either the decoupling capacitor or the IC itself. You have to try and figure out which one. After replacing the shorted component, it's better to replace this resistor also (probable chance for change in value due to the over current caused by the short/leak).

Thank you very much, I will try to replace the resistor after replacing the capacitor. Should I start with a low resistance (2.2 Ohm) first and if it doesn't work go for a higher resistance (10 Ohm) or the other way around?

In my experience, any low value resistor will work (max up to 10 ohm). Since the original schematic and/or datasheet is unavailable, we can only make educated guesses here. The other board which i referred used 10 ohm resistor in that connection. So it's definitely safe to use that.
