is there a way to check pch short without voltage injection ?...

coil from top to bottom in the pic

3.9ohm
5.9ohm
shorting probes is .7 ohm

ha65nm130 psid voltage ?
anyone know the ha65nm130 psid voltage im getting. sometimes 500 -200mv or is there datasheet schematic for this
-
should i still get psid and 3valw and 5valw , if cpu is dead?

so do i have a short to ground on the 3d3v_s5 ? or is it IC EC

continuity shows the row of inductors are short ? or is this normal?

its my own board , the cpu core inductore were already shorted, is sio and cpu short on same circuit?

i inject it into the capactiroe on the 3d3v_s5 line circuit, and ec is heating up real quick

the ec is heating up quick, i didnt inject into the pin 17ldo because i have 8v , but injecting into capacitor is safe ?

im using an 18723-1 schematic it about same as mine which is 19752-1 but the chips on there are the same on both motherboards. i think the ec was dead and is the short ? laptop no power no led dead , is ec fault ?...

i only had a 9v battery so i used that , i dont have a voltage injection....

is this the short or did i inject too much voltage and the ic will heat up too much viktage injection

the EC chip is heatup with 8v 1.9amp injecting in the 3d3v_S5 capacitor circuit it is no near the EC chip, image added
the circle in white shows area is heating up with 8v injection on EC

i inject 8v and 1.9amps into the 3d3v_s5 capacitor and the EC Chip is heating up quick ?? does that mean the EC IC is short or a capacitor?

its the resistorfor the dcin on the charger ic, there still is a short on the 3v pwm IC, should i replace this resistor before finding the short in 3v

looking for replacement 2D2R5J-1-GP
the paprt im looking for is 2D2R5J-1-GP from the schematic it is smd resistor with code 100 on it
-
just checking the charger IC ISL9538BHRTZ-T-GP , what should the DCIN pin voltage be ? mine is 1.482V
