No difference. However, your best chance of ensuring reliability is not switching off or on at all and to leave it up all the time. This is not always practical, so it is always better to use the "system" power on/off, rather than just cutting power at the source, to avoid any problems with glitches from the mains supply. If u have a good quality system., its power supply should be built well enough to protect your system from small anomalies in your mains supply; however a surge protector/power box is a good investment.

I have a question (and it may not make any sense). I was thinking: I use a system switch (turns on computer, monitor, etc...) If I turn the computer off and on at it's switch, it should immediately supply full power and cut off full power to the computer. This sounds like a good thing. On the other hand, if I turn off the system switch, this cuts power to the computer's power supply, which would then, assuming I'm thinking correctly, send dwindling power to the computer. My question: assuming the above is logically correct, does this "dwindling" effect do any long term damage to my computer? It's a personal computer, and while I've never had any major problems with it yet, I would like to minimize my chances of failure. --Michael Ginsberg Carnegie Mellon University, Pittsburgh, Pennsylvania, USA --------------------------------------------------------------------------- ARPA: mg32+@andrew.cmu.edu |Electrocution, n: BITNET:mg32%andrew@cmccvb | Burning at the stake with UUCP: ...!harvard!andrew.cmu.edu!mg32+ | all the modern improvements. ---------------------------------------------------------------------------

On all computers I've ever disassembled (4 PC/AT clones, 15 other types), the switch on the computer is used to connect/interrupt the connection from the 120vac wall current to the internal power supply of the computer. Thus, using an external "system switch" or power bar or whatever would be the same as using the "internal" switch on the computer. -Mark D D The power switch on

Unless your system switch contains capacitors for storing electricity, you should not experience a "dwindling" power effect. With the rate of electrical current flow, the system switch should cause power in all attached appliances to be cut immediately. If it is not, I would be suspicious as to the quality. **************************************************************************** * Thank You, texbell!letni!rwsys!trsvax!slimer * * Bill "I think, therefore I LAN" - ComputerWorld * * George W.
