Lots of old superstitions about that. None of them are right.
This is right:
1. Steady dc current through a connection will generate
a plating action leaving a resistive deposit in the connection
and ruining it. First to go .. ram. Repairing color tvs was
big business because of this.
Lifetime of a computer left
on is about 1 year, and then it becomes flakey.
This is utter fiction.
Ram reads
skyrocket, and bad spots develop on the hard drive.
You didn't expect to hear this?:
Tell that to my PIII 700 juke box.....been running 20/7 on average for 5
years. Using win9x!
2. Temperature change hurts a computer ??? There is much
more temp change while using a computer than when just
turning it on and off ... in a normal room kept at room temp.
Those temp changes would unseat digital ics when they
were mounted in sockets. Not any more.
3. Turning a power supply on stresses the circuits due to big
voltage surges ?? Not any more. Psupplies are designed
to slow start, and they are left in idle-warm mode when off.
Providing everything is in top working order.
4. Electricity is cheap ?? Not if you leave your computer on
all the time. It is more than $1 a day, and there goes your
$300 video card right in some Arabs pocket.
buck a day? nah....maybe 20 a month, providing the monitor is off during
non-use time
5. Hard drive bearings wear out with use. Leave the thing on,
and you'll reduce its lifetime by half or more. Fan lifetime
is very short when left on like that. And modern boxes will
fill up with dust and ruin every fan in it ... esp your $300
video card.
I suppose...seeing how the colorado cut the grand canyon....i didn't noticed
if he said that he shuts off the harddrives after so much down time. Wearing
the bearings is like saying don't use paper towels on your monitor cause
your wear the anti refective film off.....yeah maybe in a coons age.
Teach your PC to hibernate at 45 minutes idle time.
worst possible sceneario, as hardware drivers for average rigs (*other than
laptops) have a hard time waking up from Hibernation.
That means
total power down, and restart from hitting the power switch.
Restart on my PC from hibernate takes about 15 seconds
all the way back to my desktop with the app I was using
open and ready to go. All of my PCs in my engineering labs
are set to hibernate at 45 minutes.
That leaves out the average machine with average hardware
That means I only have
to do dust blowouts once a semester, and when the AC
fails, my PCs are protected ....
41 PCs in a non-AC room
will send the temp over 100 degrees
This was needed to say?
and ruin them.
would that be all 41 at once, or one at a time until the temp dropped?
