Hi, I got this board, it was working fine, I just cleaned it with isopropilic alcohol and now it doesn´t turn on. I get .56A at my PSU but no chime, image or POST. I have all the voltages present even PPVCC_S0_CPU but I get nothing... should I reprogram the BIOS? This is so weird, it was working just fine, and after I cleaned, it just won´t start...
I have no USB activity and it is stuck at .56 A this board usually goes up to .80 a and then down to .40-50 but it usually doesn´t stops at a constant consumption, please help!

No liquid damage, the board is turning on but not posting, SPI termination resistors are good... pch clock is good, what else to check?
all voltages present, when I remove the SSD PSU gets to .44 A green and orange light on the charger... cpu gets warm...

Something got damaged when you've cleaned the board.
Still suspect broken trace, or moved component.
PLT_RESET_L stays high?
Try known good BIOS, just in case.

PLT_RESET_L is present and stable. I´ve already tried a known good bios from the forum... speaker connected and not getting any sound from it either..l
