Shutdown Or Leave Running, that is the question
Below are two articles regarding pros and cons of shuttingdown, sleep or
hibernating your computer.
*I. Is There Any Reason to shutdown Your Computer
SuperUser contributor David Zaslavsky responds:
http://www.howtogeek.com/131595/is-there-any-reason-to-actually-shut-down-your-computer/
From a software perspective, an operating system and the programs you run on it
tend to accumulate all sorts of cruft over extended periods of use - temporary
files, disk caches, page files, open file descriptors, pipes, sockets, zombie
processes, memory leaks, etc. etc. etc. All that stuff can slow down the
computer, but it all goes away when you shut down or restart the system. So
shutting down your computer every once in a while - and I do mean actually
shutting down, not just hibernating or putting it to sleep - can give it a
"fresh start" of sorts and make it seem nice and zippy again.
However, different computers and OS's are not all equally affected by this
phenomenon. Generally, a computer with a lot of RAM can go for much longer than
a computer with only a little RAM. A server, on which you just start up a few
programs and then let them work, will be fine for much longer than a desktop
computer, where you're constantly opening and closing different programs and
doing different things with them. Plus, server operating systems are optimized
for long-term use. It's also been said that Linux and Mac OS tend to run for
longer than Windows systems, although in my experience that mostly depends on
what programs you use on them, and not so much on any differences between the
kernels of the operating systems themselves.
*II. How-To Geek
Should You Shut Down, Sleep, or Hibernate Your Laptop?
http://www.howtogeek.com/128507/htg-explains-should-you-shut-down-sleep-or-hibernate-your-laptop/
Computers can sleep, hibernate, or shut down. Sleep allows you to quickly
resume using your laptop at the cost of some electricity. Hibernate is like
shutting down your computer, but you can still resume working where you left
off.
There's no right answer in all situations. Some people leave their computers
running 24/7, while others shut down computers the moment they step away. Each
of these options has its advantages and disadvantages.
Shut Down vs. Sleep vs. Hibernate
Each of the three power-down states appears to shut off your computer, but they
all work differently.
· Shut Down: This is the power-off state most of us are familiar with.
When you shut down your computer, all your open programs close and the computer
shuts down your operating system. A computer that's shut down uses almost no
power. However, when you want to use your computer again, you'll have to turn
it on and go through the typical boot-up process, waiting for your hardware to
initialize and startup programs to load.
· Sleep: Also known as Sleep or Standby. In sleep mode, the computer
enters a low-power state. Power is used to keep the computer's state in memory,
but other parts of the computer are shut down and won't use any power. When you
turn on the computer, it will snap back to life within just a few seconds. You
won't have to wait for it to boot up - everything will be right where you left
off. However, this uses more power than shutting down or hibernating your
computer.
· Hibernate: Your computer saves its current state to your hard drive,
essentially dumping the contents of its RAM into a file on its hard drive. When
you boot up the computer, it will load the previous state from your hard drive
into its RAM. This allows you to save your computer's state, including all your
open programs and data, and come back to it later. It takes longer to resume
from hibernate than sleep, but hibernate uses much less power than sleep. A
computer that's hibernating uses about the same amount of power as a computer
that's shut down.
If you put your computer to sleep and its battery becomes critically low, the
computer will automatically go into hibernate mode to save your state.
When To Shut Down, Sleep, and Hibernate
Different people treat their computers differently. Some people always shut
down their computers and never take advantage of the convenience of the sleep
and hibernate states, while some people run their computers 24/7.
· When To Sleep: Sleep is particularly useful if you're stepping away
from your computer for a small amount of time. You can put your computer to
sleep to save electricity and battery power. When you need to use your computer
again, you can resume from where you left off in just a few seconds. Your
computer will always be ready to use when you need it.
· When To Hibernate: Hibernate saves more power than sleep. If you won't
be using your computer for a while - say, if you're going to sleep for the
night - you may want to hibernate your computer to save electricity and battery
power. However, hibernate is slower to resume from. If you're hibernating or
shutting down your computer every time you step away from it throughout the
day, you may be wasting a lot of time waiting for it.
· When To Shut Down: Most computers will resume from hibernate faster
than they will boot up from shut down, so most people will probably want to
hibernate their laptops instead of shutting them down. However, some computers
or software may not work properly when resuming from hibernate, in which case
you'll want to shut down your computer instead. It's also a good idea to shut
down (or at least restart) your computer occasionally - most Windows users have
noticed that Windows needs an occasional reboot.
The exact amount of power used by sleep and hibernate will depend on the
computer, although sleep mode generally uses just a few more watts than
hibernate. Some people may opt to use sleep instead of hibernate so their
computers will resume faster - while it does use marginally more electricity,
it's surely more power efficient than leaving a computer running 24/7.
Hibernate is particularly useful to save battery power on laptops that aren't
plugged in. if you want to take your laptop somewhere and you don't want to
waste valuable battery power, you'll want to hibernate it instead of putting it
to sleep.
Making Your Choice
Once you've made your choice, you can control what happens when you press the
power button on your computer or close the lid on your laptop. To do so, press
the Windows key, type Power buttons, and press Enter. You'll see the power
button options in the Windows Control Panel. (On Windows 8, you'll need to
click the Settings option on the search screen after typing Power buttons.)
You can modify your computer's power-saving options to control what it does
automatically when you've left it idle. Consult our article on sleep vs.
hibernate for more information. Found at the link below.

"Thank you Father, for your grace and all things not visible, I am grateful. If
even now I could see all that you are, my eyes, mind and soul could not hold or
comprehend your brilliance. I have nothing
to prove your presence beyond the love you envelope and spill from me through
your Spirit.
Our faith in this love is the culmination of Jesus and all that he accomplished
at the cross. Our
souls were the recipients of His great love, and for that, our hearts are Yours.
