Acer zc-606 - Short Circuit

[speedypro]

Got this board Im trying to diagnose. I have a short (dc jack "+" and "-" are short). Ive removed the dc jack to see if that was the issue. Ive removed a diode to see but same short. In red, Ive replace that IC but same issue. Are pointers or schematic?

Take off those 0ohm resistors near your red mark MOSFET and check short where it goes towards mobo or towards dcin

try remove tcp 8127 then put jumper wire or inject 19v at drain you will see what will be hot, in mine ive got short cap nere power switch replace parts then ok. below sata port
