I remember back when I was a kid, I heard of a "One Minute Rule" like if you shut down your computer, you have to wait a minute before turning it back on. Or else something BAD will happen. Anyone heard of this?
 
I have never heard of it, sounds like a bunch of phooey to me.
 
Sounds like a load of crap, but then again, I wasn't exposed to the really old computers. :p
 
back in the day of the apple IIc, flicking the switch on and off would cause the disk drive (we'er talking old 5.25 drives here) to run out of sink , thought i never saw it happen in practice... also, there was a time when the harddrive head acctualy floated over the platters on air, (now they float on a coat of oil), and on the older 10mb harddrives it could cause a head crash, i was also told at some point in time that its simply better to let the hardrive spin all the way down befor you hit the go button, i doubt it make any noticable difference in modern drives however

with modern pc's its not a problem... unless you have a shotty psu.. theoreticly, if the psu is hot, (a hot psu produces less power) and you flick the power off and on again it could cause a power surge that could take the psu out of spec (if its running close to full load already) and might break shit if it blows... however, i think for this to acctually happen, you would have to be over taxing the psu as it is..

i doubt many people on this forum will have any trouble with quick turnaround times between shutdown and startup

I remember back in the old days of the Apple IIGS and such the teachers told us to wait a while before turning them back on. As thore said it could have come out of paranoia that the heads on older hard drives wouldn't get back to the landing zone and possibly cause some harm to the platters. But on modern computers, you don't have to wait a minute. I usually let all the fans spin completely down and then turn it back on, but that's more like 3 seconds, not 60.
 
If there was one minute rule then every system I've had since and including my 486 would have died a fiery death or something. I've had plenty of Bad Things happen with my systems over the years but it has never been because of turning the system off and back on in less than a minute.

 
i was told to wait so that "the memory could clear". Considering that the DRAM refresh happens at least 1/second (personal estimate, based on no facts whatsoever), I really doubt that waiting more than one second is required.
 
Yeah, you should let the caps discharge before turning it back on, but anything longer than 5 seconds really isn't necessary.
 
I always let my drives spin down before powering back on.
 
Back in the dark days, I remember hearing about not flicking the computer off and on. But
there was never a definitve reason behind it, just that it would make bad things happen. Don't
tell this to a young mind that likes to take everything apart. I did it many times, and never
had an issue. The drive sync thing actually sounds like a reason I would have listened to.

Back then I was using an Apple //c, and never had a problems with the old floppies. Later
on I upgraded with an add-on card from Beagle Brothers. It upped my system to 1 meg of
memory, a zpm coprocessor, and a clock card. It had an odd thing, though. You could reboot holding a key, I think it was shift, and it would not clear the memory, and it would be
like coming out of hibernate mode with your OS already running intact. I don't recall the
details as I haven't seen that machine since about 92 or 93.

Even in the last few years, I've heard that it should be left off for 15 seconds. I doubt there
is much to it though.

I would say either let the drives slow down, but my dad always told me that you had to leave the computer off for a few seconds...like 10-20 to completely clear the memory...dont know if thats true either though...

I think its actually some time window thats rediculously small....like if the memory looses power for more than like 100 nanoseconds it erases....not sure, but it is very short.

The only "one minute rule" I remember was the lenth of time your food could hit the floor, and still be OK to eat! :D
Computer-wise, I always heard 10 seconds.

With ATX the caps are always charge unless power is cut off from the board by either unpluging it, or fliping the PSU switch.

I second that. This is also the only 1 min rule I have heard of. Even though I would not eat off the floor. I usually wait like 5 seconds until I restart.
