You know when you "turn off" your screen, do you actually save power?

In the past the savings was significant with CRT monitors; not only does one save on the electricity, but one also prolongs the life of the tube and circuits inside the monitor.\n\nLCD screens use far less power than CRTs, and so you'll get great savings if you retire your CRT and replace it with a LCD.  So do this if you haven't already.\n\nSwitching off an LCD will save a little, but not significant amount, since they are already so efficient to begin with.  Switching off also protects against unexpected power surges that may damage your monitor.\n\nHaving said that, I still switch off my LCD and computer if I don't expect to use it for the next 2 hours or so, and I always switch off every night before going to bed.

What about just unplugging it?

Yes, of course.\nLaptops are made to be charged, and they charge fastest when shut down as they are not relying on power. I have to contradict what someone has said; I leave my laptop charging overnight all the time, and it has not done any damage to the battery.\nI hope what you do, is if you are using the laptop during the day you do not have it running on AC power, I'm pretty sure it is better to be running on battery.

Depends on how long ur gonna leave it 'idle' for, if its for more than 5 hours, turn it off (eg over night) any less and i'd say let the screen saver run.\n\nOr better yet, use the hibernation option :D It saves all work on ur pc in temp memory than shutsdown, once restarted it opens all the programs that were open previously :D

Very little cost.  :)   Computers use very little power, and electrical power is cheap.  If you left your computer on 24 hours a day, you're probably using roughly 10 cents of electricity in a day.  Turning it on and off is hard on the hard drive.  Good rule of thumb is to turn it on when you go to use it, and leave it on the remainder of the day until you're done with it for the day.  You can turn on and off the screen, that'll increase your screen life.  But turning it on and off a lot puts stress on the hard drive.  Mostly leave it on once it's on.

Your network card may be going into power save mode when you leave your computer idle for a while.\n\nTo disable this:\nYou can use Device Manager to change the power management settings for a network adapter. To disable this setting in Device Manager, expand Network Adapters, right-click the adapter, click Properties, click the Power Management tab, and then clear the Allow the computer to turn off this device to save power check box.

I believe most laptops either have a standby or hibernate feature where after a certain time the laptop shuts off automatically. i don't think it's bad to leave it on all night, but if you're laptop has this feature, there's no need to worry about it. it'll turn off by itself.

Open Control Panel, go to display, go to the screen saver tab and click the button labeled "POWER"   Easy from there.

Short answer: no.\nLonger, more complete answer: it depends.\n\nWhile on, the UPS uses a small amount of electricity (which costs a small amount of money), produces a small amount of heat (which makes air-conditioning run a tiny bit more, which costs money), and provides a small charge to the battery in the UPS which keeps it in tip-top condition (maximum battery life).\n\nWhile off, the UPS uses no power and produces no heat, but the internal battery "self-discharges" at a slow rate.  This means that you won't have 100% capacity when you turn it (and the computer) on, and the repeated small self-discharge & re-charge cycles will slightly shorten the life of the internal battery. If there are long periods when the computer (& UPS) would be off (like weeks), then this self-discharge could be significant.\n\nSo, if electricity is hideously expensive, or air-conditioning is costly or unavailable, then turning off the UPS might make sense.\n\nIf you've got no money to replace the UPS and the battery has to last as long as possible, leaving the UPS on makes sense.

Are you turning off your whole system without signing off of everything? Sometimes, when people just hit the computer's power button without signing off of everything, the computer automatically remembers the information and when you turn your computer back on, you're still signed in. It happens to me all the time.

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

Go to My Computer->Control Panel->Display->Screen Saver.  If you want to, you can just turn them all off by choosing <None>.  But you may also choose to turn it to a different one, or Blank Screen.  "Blank Screen" is just that; it will go to black.  "None" means it will never turn off the page you are looking at, no matter how long you go away and leave it.  That's hard on the monitor.  That is, if you leave your monitor showing the same static display for a long time, you can burn it.  Then you have a ghost of the page when you go on to other things, and you shorten the life of your monitor.\n\nHowever, you may also find that there are other screen savers on there you didn't even know you had, because Windows generally comes with a variety of them.  Why not change around sometimes, but still give your monitor the saving?  Or even download some of the millions of free ones out there, and come to love your screen saver as much as I love mine.  It's from Scholastic Books, and has a lot of pictures from the Harry Potter series.  Very cool!

Go to Control panel then Display when the box opens go to Screen Saver and at the bottom where it says Monitor power click power and on the drop down bar make sure it says Power Scheme Always on. If it does not say that then drop down the bar click on Always on then click Apply then Ok. That means when you shut down you will have to manually shut the monitor off.

Its due to the Power Saver option being active. You can change the settings from Start>Control Panel>Power Options.

Go to your desktop, right click and hit properties, Go to the screen saver tab and choose monitor power. Change options to keep the HDD on and no standby or hibernation. See if that "cures" the problem.
