If you get PM_SLP_S4_L, there should be S3 voltages present; like L7430, L7820.
Did you check PM_SLP_S3_L too?
If present, only then you can expect S0 voltages; check L7630 and page 58.

 

[yair37]

L7430 1.2V
L7820 1.7V
PM_SLP_S3_L 3.3V

L7630 1.1V
PAGE 58:
PP1V5_S0 0.5V
ALL THE REST LOOK FINE

It comes from U7870; post all its voltages.
Check diode mode to ground at 1V5_S0.

 

[yair37]

u7870:
1.PP1V5_S0 - 0.5V DIDO MODE 375
3.PM_SLP_S3_BUF_L - 3.3V
4.PP3V3_S5 3.3V
6.PP1V8_S3 1.8V

 

[2informaticos]

Change it...

 

[yair37]

replace it twice, the same..

 

[yair37]

and its getting hot...wierd..NO SHORT!

 

[2informaticos]

Diode mode to ground at R8041?
You can check what happens removing U8040.
I recommend to try first disconnecting LIO flex.

 

[yair37]

was corrosion on J9500.
R8041 short on PP1V5_S0SW_AUDIO_HDA. NOT FROM C1210 OR FROM Q1920. I THINK FROM CPU.
witout R8041 fan spin, with is not..

 

[yair37]

turn no but of course no audio

 

[2informaticos]

Post exact ohm resistance to ground at PP1V5_S0SW_AUDIO_HDA.

 

[yair37]

PP1V5_S0SW_AUDIO_HDA diode mode 002 from R8041

 

[2informaticos]

You can try to inject 1-2V (no more) there.
It will probably heat the PCH, without solving the problem; just for confirmation.

Look en Internet for portable USB speaker.
You should find some model specially designed for laptop, to attach on top of the screen.
