help, please, with Compaq Presario power supply problem
Hi. I'm helping someone with a Compaq Presario 5320US desktop that
won't power on at all. The problem occured when the PC was moved from one room to another. A previous tech told the owner to just go buy a standard 350 watt power supply (which she did) and that he'd then install it. This happened, apparently, without the tech even bothering to do any actual troubleshooting -- plus, he was also apparently ignorant of the fact that this Presario uses a non-standard proprietary power supply. The owner can't get ahold of that guy now. So, the owner says to me: can you fix it? I can't even plug in the replacement standard power supply because the motherboard has a 24-pin connector instead of the standard 20-pin. Similarly, I can't use my quick-and-easy power supply tester because the old power supply won't plug into that. I'd go ahead and start probing with a DMM for proper voltages, but I'm under the impression that I'll get nowhere with that if the power supply isn't already on and under load. Finally, without a known good power supply, I can't even tell whether the power supply was actually the problem, or whether it was instead something else. Any suggestions as to how to proceed? I did come across a web site that sells 24-pin to 20-pin adapters, but does anyone know whether such adapters even have a standard wiring pattern? Since the Compaq supply is non-standard, how would I know whether the adapter would be wired properly for it? I found that the customer can buy an exact replacement part from the HP/Compaq web site for $150, but doing so seems silly before we even know where the problem lies. Any help appreciated! Jacques |
