Re: [CGUYS] What do your recommend? (was Electronic Failure)
Simply shutting down doesn't protect against lightning surges. You must unplug the power as well as any wired connections. Too much trouble for most of us; get a UPS. My own comp is turned off for the night if I'm not doing anything with it. Our office machines are often left on for rendering, otherwise off. I'll sometimes hibernate laptops, but some hardware (eg network cards) seem to get confused at that, so it's power-off for them too. I don't bother with standby at all. But I imagine if our office environment was such, I might encourage it as a security measure. Turn on or wake the computer the first time you need it that day. Save work and standby if you are away for a few hours. Save work and hibernate when you are finished for the day. Shut down immediately if there is an active severe thunderstorm over your location. Reasons: Extends life of computer, saves energy, protects work. * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?

Re: [CGUYS] Speeding Up XP [Was: Vista Memory Needs
Many years ago I witnessed a laboratory demonstration of the power of lightning. They rigged up a very high voltage spark (a shadow of a real lightning bolt) and had it jump to a block of wood. In an instant, the spark jumped and the block of wood was just gone. In that instant, all of the moisture in the wood was turned into steam, and the steam just shattered the wood into dust. Once an hour at the Franklin Institute. I wonder if they still do this? * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?

Re: [CGUYS] electronics failures
Could you refine that answer just a bit? When I sleep the various 'Books, for wear purposes, does sleep count as being turned off? I'm inclined to think it does, as it is my regular practice, but eagerly await your thoughts. Yes. Computers do now always wake from sleep or some parts wake while others don't. So I usually avoid sleep. * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?

[CGUYS] Lightning

It took out a computer, which was unplugged and disconnected from the telephone line, buy entering via the audio inputs and outputs which I had connected to audio gear.

No type of surge protection can ever guard against such power. You gotta unplug it all when those storms come unless you are ready to pay the price, and that season will soon be upon us again.

Things are better in cities because there are good grounds--everything is grounded, particularly in modern construction or high rises. The worst is in the country near the end of the power line. Then even well-grounded electromechanical things (like the well pump) can be burned out. Replace your surge arresters from time to time. The diodes fail in a cumulative manner (a little weaker with each surge), and they fail in such a manner as to fail to block the surge. Nothing will protect against a direct strike of lightening. I think it takes 30,000 volts to jump a spark through one inch of air and the lightning has gone thousands of feet. The theory of the lightning rod is that you provide good paths to ground. There is some question as to how effective lightning rods are in normal installations. I hear contradictory stories about whether underground lines are more or less susceptible to strikes. I think it depends on the soil. The people who told me they are less susceptible were here in the east with sandy, loamy soils. The people who told me more susceptible were in an area with very rocky soil and lots of exposed bedrock. * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?
