Hello,
I have a 820-4668 not booting, after a few measurements, don't see obvious short or any heating.
I have the 1st LED but when pressing power botton has no reaction.
my confusion is that in no_boot state i have S5 state power rails(which i do have). but the board is pushing out PM_SLP_S5_L(3.3v) which is S4 enable before power button is pressed, Is this normal?
i have pp3v3_s4 but no pp5v0_s4. should i start my troubleshooting here? pin 24 of U7600 is 3.1v but no pp5v0_s4 output
