how does electricity reduced by shutting down pc monitor?

One does not need studies to know that turning something OFF uses less elecricity than something that is ON. Just like a car that is not running uses less gas than a car that is running..whoooaah

If you had power issues then lagging would be the least of your problems. A switching power supply will shut down if overloaded. If you are concerned that your PC may be getting close to pushing the limits of the power supply, You can check the the amperage either on the AC or DC side with a clamp-on amp meter to determine the load the PC is drawing.

On the desktop right click then go to properties.  Under screen save go to power stettings.  Just turn "shut down harddisks, sleep, and hibernate" to never

The answer changes because there isn't just one right one. Power cycling your machine stresses parts as they heat up and cool down, cope with inrush current as they come on, and so on. This is not good for the life of these parts, but if they're able to survive for a decade you probably won't care by the time they fail as the machine will have been retired in favor of the much more powerful computer hat that will be available.  \n\nHowever, only the military and the space people design stuff to such high levels of reliability, and even they (or their suppliers) get it wrong on occasion. \n\nSo the question you're really asking is, will power cycling my machine more often than x times cause trouble. And there's no one answer to that. Leaving the machine on causes problems (dust deposition impeding proper cooling if nothing else) and uses electricity, so that's bad. Turning it on and off causes problems (that stress stuff mentioned above), so that's bad too. And leaving it off, isn't so hot since you can't use it when it's off. \n\nThe answer to your question is therefore a sort of balancing act you must perform, but without full information for your particular machine on the relative damage / costs being caused by leaving on as contrasted to turning on and off. \n\nThe best (not definitive) answer I've ever found is to turn it off when you (or someone) won't be using it for a few hours. If you'll be back in 15 don't bother -- except that security issues may suggest you not leave any software running or that you should log off or some such. Gone for the evening, turn it off. \n\nA last point has to do with particular parts. All sorrs of  monitors can burn a pernament pattern into the screen if left on for long periods. That's why there are screensavers, to keep the display changing while nothing else is going on. And CRT type monitors both draw a substantial amount of power (Energy Star monitors will shut down to a 'warm off' if not used for a while), but also have quite high voltages internally which cause more than the usual amount of electrical stress on insulation, capacitors, and such. And the LCD screens use cold flourescent tubes to back light the screen; they're expensive to replace in almost all cases, so their limited lives shouldn't be frittered away in useless idleness. Even if you don't turn off the rest of the machine, consider turning off the monitor. \n\nYou should also consider that the mechanical bits will have a limited life. Consider hard disks. If your machine keeps the disks spinning whenever the power is on, you shouldn't leave it a 'rotatin when the machine isn't being used. Disk death may take data with it and that's not a nice thing. Perhaps even a complete disaster. Many machines shut down drive rotation after a certain duration of disk inactivity. Check yours to see what it does. \n\nSame goes for cooling fans (in power supplies, mounted on the CPU, or video processor chip, attached to the back of the chassis). Some CPUs (and video processors) draw so much current that, without the fan cooling, they will fail permanently from runaway overheating in minutes if the fan fails. Some systems have temperature monitors for the CPU (and alomst never for the video processor chips) which will cause an emergency shutdown of the machine if the temperature goes too high (ie, if the CPU fan fails). Yours might, and that's good, but your software had better not loose data when that happens, or scribble all over the hard disks as the power goes down. If it doesn't, you probably don't want to leave it on when someone isn't around to take quick action if something fails. If you get an option, the ball bearing fans have longer lives than the roller bearing ones. But they cost more. \n\nThere are multiple considerations in answering your question, as you can see.

1. I have a UPS hooked to my firewall / router and also have 7 networked systems, and keep three computers ON at all times.\n\n2. I have serviced delicate computers and peripherals since 1965, the first 20 years on active duty in the USAF.  Some were mobile, on the ground, or in the air.\n\nMy experience is that the systems left on all the time cost less to keep running, than the ones that get turned off and on.\n\nThe biggest user of energy is the CRT monitor, so they get shut off at night.  And, I am switching to LCD monitors, having three so far.  \n\nThe CRT monitors use between about 200 watts (15 inch) and 400 watts (21 inch).  The LCDs use 20Watts(15") to 40 watts (19").  The LCD monitors us less power when fully on than the CRT monitors use when 'asleep'. \n\nThermal cycles of Power On vs Power Off cause failure.  Many computers that have run successfully for years will not start back up, after they have been shut down.  \n\nIf parts are going to fail, it is usually during the surge of current flow upon start-up. \n\nAlso, Microsoft FAT, FAT32, and NTFS do seem to cause a higher failure rate than Linux EXT2/3, ReiserFS in all my experience.  One more reason I run http://pclinuxos.com

Yes because sometimes lighting can get through the electric lines and damage your PC if the building does not have proper "earthing".  Safer still, after turning off the computer, remove the plug from the socket too. Replug only after the storm has gone

Your moniter is shutting off because of your power settings. To change this right click anywhere on your desktop background and click properties. Go to the screensaver tab and there will be a button near the bottom that says Power. Click that button and another window will come up with your power settings. There will be an option that says "Turn off moniter" near the middle of that window and it will have a scroll down option next to it. Select the Never option and click apply. Than click ok, and ok again at the screensaver tab window. After you do that your moniter will not shut off on it's own like that again.

Off of coure is it's for hours but for short piorod's of time it wont hurt to leave it on. But even you computer needs it's sleep some times it will help it! Just like sleep hepls you! Plus you save on your power bill!

Yes. Easy. Go to  the energy saver in system preferences and regulate the turn off time there.

try CPU (processor) cooler there is an sensor under the cpu socket on the mainboard so when the cpu gets hot it turn`s off the pc and wont turn it back on until it gets cooled down,since you power it manualy
757621
yes.  \n\nturning off the monitor will not affect ANYTHING and you can always turn it back on.  \n\never played video games as a kid and had to pause for dinner, and turned off the tv? =)

Shutting down your PC should ALWAYS be done by using the "shutdown button". Windows will unload certain components from the memory, save it's present settings and flush the virtual memory when doing so. \nAs stated in the former comment, shutting it down by the power switch (aka hardware reset/shutdown in contrast to software reset/shutdown) will result in the loss of ANY non saved information on your pc and mey provoke STRANGE results on boot-up (desktop settings lost, driver missing etc...). It should ONLY me a last step measure when the pc hangs (does not respond).

Only if you dont restart or shut down your computer can you avoid that welcome windows. \nIf your Compputer can start in hibernation mode, then instead of shutting down your PC, put it in hibernation mode. \nBut that means ur computer is like on 24-7. it takes less power, but its still on! and some times you have to restart wen you install something!!\n\nIn a Hurry, Use HIBBERNATION

There is a piece of hardware in the back of the computer called a Power Supply. It converts the electricity from the wall into something the computer can handle. The Power Supply also has a off switch. If you hit that all electricity ceases to your computer, thus making it impossible for the computer to turn on. When that light is on it means the computer is receiving electricity.

Yes. Assuming you have a PC: Go to your Control Panel and open Power Options. You can change the settings for your sytem's stand-by and hibernate options, or turn them off completely.

its a way for your computer to save energy while its not in use.

Right click on the desktop, go to properties, click the Screen Saver tab, then click Power. Where it says Turn off monitor, Select never. same with hard disks and system standby, put those on never.
