![]() Good Day,
Model : HP 15-p004nx Boardcode : day11amb6e0 Issue : When plug in, fan spins for a seconds then off, When power on current responds up to 0.12A then back to 0A but no fan spin. Checking the voltages, VCORE is missing checking enable signal, VRON also missing and already tried to flash bios and replace the SIO but same issue. Another signal is also missing HWPG, i tried to look for the cause, I already tried cutting the lines coming from powergood signals of 1.05V , 1.35v ram supply and 5v supply ic but nothing change |

![]() The fault must be earlier in the sequence. Find Out what exactly is Missing should give the clue. Of course, Schematics will Help a lot Here.
And it Would be also a good start to Check whether PGood is released at Supplys with Expected Voltage present. A few days ago i Had a Board Here, some technicians already Messed with it. 1.05V PGood Not released and additionally the EC was somehow "stuck" after fixing the PGood. A bit of "stabbing" the the EC and corresponding components of Missing PM_SLP_S3# solved the issue. Board works stable since then. And this is Not the First Time i fixed Something while "stabbing" around the EC and the VRM. Happened already a few Times to me. |

![]() You're talking about U16? Probably not present because a optional component.
Which PGood exactly is missing? H_PROCHOT# low or high? |
