HP 13-AD017NC, no POST, LED OK

[jaroslav.psenicka]

Hi guys,

I've got HP 13-AD017NC board 6050A2919201-MB-A01, not POSTing,

• some voltages are present, see attachment
• no direct short
• no USB activity
• LED is on
• power button shorts to ground OK
• no fan spin
• CPU is warm, GPU stone cold

what do you think?
haven't tried the BIOS flash, not sure where the chip is
may be the SIO chip?

thanks

oh, the PCH is getting hot when the board is powered
also, as mcplslg123 mentioned here, the 1R4 to ground at 1V rail is "considered too low indicating perhaps towards a shorted PCH"
