The reason I ask is that the place where I used to work just leased a large number of the new black desktop machines and part of my job was to assist with the setup of these machines (ie. Take them out of the box, put them in the right location, install the software). One thing that concerned me was that the power cord/plug on the pc/monitor end produced a ?fuzzy, buzzing sound? (much like what you get when something is short circuiting) when either the plug was loose, or when I was plugging/unplugging the hardware. It isn?t something I have seen on any other pc I have worked with (and that?s quite a few). I am not an electrician but this sound does not sound like a normal sound a computer should make. Has anyone heard this sound on their compaqs? On any other pc? Does anyone have any other comments to make? I would be interested to know if this is just me or if this is something that compaq users should be concerned about.	Guest (0)

They normally sizzle to failure (shown by a dark brown or black colour on the outside of the white plug, and sometimes smoke). It is because the very thin brass used for the connections is folded around the wire and crimped. The plug is then injection moulded around the connectors. If the crimping is not tight enough, the wire arcs to the connector. This creates heat. This could be the problem, but I hope that Compaq would have better quality control than that. I have seen some IEC cords (especially jug cords) which might be made that cheaply. I would not use them in any application involving a lot of current and being left on unattended. You can usually see the difference in quality. If your sizzling was only when the plugs were not fully inserted, it's most likely the sparking you get because the power filters on the input of the PSU pull a very small current even if the unit is switched off. You must have had a quiet workspace. If it was noisy, and it was a major cable fault, you would have had a fire or at least some smoke when the computers were on for a few hours.	Guest (0)
