Re: hp 9000 C3750 hardware problem (partially off-topic)

Looking at the pads by the 24, I don't believe anything was ever soldered onto those pads. Double check the motherboard again for empty pads, and post pictures. You might also want to inspect the PCB's on the hard drives for evidence of missing caps. And any other cards that may be in the computer.

Hello HPPA community, and forgive me for this off-topic, but I really don't know where to ask.

I have an HP C3750, and today I was moving it from the garage to a (hopefully) stable and operative position. While moving it, I heard clicking inside it. I opened and found a tantalum capacitor loose. (photo https://drive.google.com/open?id=1l2YQZoiqVUVnl86-GgWdhghdLfpNEcwneQ ). I checked the mother board, and I suspect it detached from the position "24" on the centre left of the photo https://drive.google.com/open?id=1nKsaqQWNHBItPKLusSSTFgCYB4jNI2JQOA next to the right of that big unpopulated connector 3 x 12.

If anybody have an HP C3750, would be so kind to check if in that position there is, or not, that capacitor I found loose, and with what polarity (where is the darker band)?

Thank you all very much and sorry again for the off topic.

best regards
