[mike@procario.org: Re: [wplug] tripping power supply]

[Phil Walther, Jr.]

I had mentioned thermal cycling.  What this is (used to happen a great deal)
is that from the temperature cycling within a computer case and the
components (even while operating) causes a tendency to work loose chips and
such.  Also, this could have an effect if, for instance, you have an
unusually long solder point on the back of your motherboard that grounds out
on the case when moved, or if it is close enough, could touch from thermal
cycling (expansion and contraction of components from heat cycles).

>From what you responded, your current system's power supply seems
sufficient.  Have you cleaned the system out lately, such as dust and such.
I'm not sure about yours, but some power supplies have a thermal sensor that
will shut the system down when it gets too hot.  Just another thought.

I have gotten lots of suggestions. Thanks. It is a 300 watt supply. I
added a parallel port zip recently, but I would not expect that to
increase the current draw much. I have been running with one hard drive,
one CD-RW, on-board LAN, riser card modem, 256 MB. The external zip has
its own power supply.

I have been running all day since the last trip with the case open. I
guess it has been 10 hours since the last trip. I have not figured out to
check my tempertures yet. I am running Mandrake 8.2. I found some
Windows diagnostics on the motherboard driver CD but they did work when
I tried them in Windows 98.

Somebody suggested thermal cycling. I am assuming a better supply would
fix this.
