I am looking at a puter that fails to power on, its owner tells me that nothing has been added, it just failed one morning to power on. I followed instructions from HP's website with no luck, is there a way to check if the power supply is working?...

You can bench test it but you need to know the connections. Substitution is a much easier way to test, if another supply works on the computer then you know where the problem lies. BUUTTT there is more than a small chance that something else shorted out and pulled the power supply down with it. So disconnect anything not required for booting, like the floppies, cdrom, etc, and try it. Try it with the old supply first, then the new one.

I connected a working power supply and plugged just the HD and the puter booted-up, but when reconnecting the faulty one, nothing happens. I also connected the faulty one to where the working PS was, and a green light lit up on the motherboard but the puter failed to boot-up. So I guess that the PS is broken, right?...

When you say that I need to know the connections, you mean that I need to know which connector goes where as to, power, fans, floppy drives, cd drives and hard drives, right?, because the connectors for the drives, except the floppy's are the same, the fan's and the power's are totally different from the drive's...

Pretty good indication of a bad power supply! Don't replace it with a cheapie, get the best you can afford.
