This said and well received, it is important to remember that the greatest power surge, I believe, comes from turning off and on the monitor. This is why it used to be suggested that one turn on the monitor before turning on the rest of the computer. Now we have to also take into consideration the laser printer. It often powers up to several thousand volts. That too will cause a possibly large surge. How a surge suppresser fits into this mix, I'm not exactly sure since it protects from external surges. Any thoughts on these surge issues? -- d Ron Allen wrote: >>At work, manager hates it when we shut down computers.
