HP Pavilion Gaming short circuit

[JohnPaul]

Hi guys HP with board X1PD, "Boot option not found" on start up, no volts at hard drive. Clusters of caps in the centre of board all seem to be shorted, I've sprayed freeze spray on both sides of the board but cant find anything getting hot. Any suggestions?

freeze spray shouldn't be wet . where did you get it from ?

Re: HP Pavilion Gaming short circuit

My freeze spray freezes then melts leaving a wet residue. I usually brush on isopropyl and then give it the once over with the hot air station. I thought they all worked like this. It is electrical freeze spray. The caps in the centre are all shorted, laptop does power on, just no volts at the hard drive....just realized I posted in the wrong section, I do believe it was late when I originally posted

Those caps are connected in parallel, so if one shorted out then they will all show shorted circuit, if the load is shorted out then you will also get short circuit reading.

It's condensation from the humidity in the room.

N.S. = not shorted
S = shorted
nothing burnt, nothing getting hot

Re: HP Pavilion Gaming short circuit

You need to remove the caps to see if the shorts will go away or not first, if the shorts are still present then you need to trace the circuit to find out what it is connected to that may have shorted out.

Re: HP Pavilion Gaming short circuit

If you had a short in a power rail, the motherboard wouldn't post at all, the HDD needs +5V, try to find the schematic, you likely have a missing signal/bad mosfet.
