Dead Hp x360 15-eb1043dx

[CraigR]

No power. I found what was a massive short under a thermocam at RT6256B 3.3 volt so I made sure no caps were shorted or anything and ordered that chip put the new one on and same thing gets hot fast. No 3.3v at the coil under it either. I have spend a very long time visually checking for any physical damage and checked just about all the caps on the whole board and mosfets. I can't record video with my thermocam but I recorded a video using alcohol. I have no idea where to go next. HELP!

Here is the datasheet

Check Resistance to GND on pin11 and pin9(No power source attached)

9.46k on pin 11 and pin 9 420k and rising.

Are you sure you counted the pin correctly? If yes, going by your measurement there is no short on VCC as well as 3V LDO.

But since IC is still heating up,there has to be a reason.

Another reason could be short in RTC secion. check it carefully.

Yes, I went according to the numbers in the pdf.
