Does leaving the computer on all night waste a lot of electricity?

Answer 1

For desktop pc better performance, I suggest you set your desktop background/wallpaper and screensaver to "none", then right click on desktop, click properties, click 'appearance', choose ' windows classic style'.
Then Start/Settings/Control Panel/Display/display properties/screensaver/monitor power/power schemes/settings/turn off monitor after 10 minutes, and set the next 2 drop down boxes ( 1. Turn off Hard Disks, and 2. System Standby) to "never"/apply/ok/ok.

Go to Start/Settings/Control Panel/System/Advanced tab /under Performance click on Settings / Visual Effects tab/
Adjust for best performance / Ok / Apply / Ok
Then Start/Control Panel/Display/display properties/screensaver/monitor power/hibernate/take check mark out of "Enable hibernation"/apply/ok/ok. Do not to use hibernate on desktop. Standby & Hibernate Issues in Windows XP = http://www.kellys-korner-xp.com/xp_standby.htm

If I'm going to be away from the pc for more than an hour, or whenever there is lightning in the area, then after shutting it down properly, I unplug the UPS (which all the computer stuff is plugged into) and disconnect the cable.

Answer 2

Think of it this way. If your computer has a 300 watt power supply, and to keep this simple, uses all 300 watts, this is equivalent to leaving on 5 - 60 watt lights on in your house. You pay for electricity by the kilo watt hour, (1000 watts = 1kWatt), so every 24 hours, you have used 300 x 24 = 7.2 kWh of electricity. Check your utility bill to see what you pay per kWh, then you will know how much money keeping your system on 24/7 uses.

PC does not use a lot of electricity. Actually, constantly turning it on and off does more damage than leaving it on, however, I would turn off the monitor when not in use for a couple of hours.

Answer 4

the different solutions aside, I in simple terms checked my pc pc, the capacity furnish attracts a million.6 amps @ a hundred v (must be a hundred and ten or one hundred twenty v, oh nicely). amps x volts = watts. My pc charger consumes one hundred sixty watts. My workplace laptop device has a three hundred watt capacity source. My liquid crystal reveal reveal screen makes use of a million amp @ a hundred v (see above). My pc makes use of the equivalent of four - 40 watt lightbulbs, the laptop pc (at top) makes use of the capacity equivalent to 7.5 - 40watt lightbulbs, the liquid crystal reveal reveal screen equals 2.5 - 40 watt lightbulbs. Sums of computers = 560 watts = .560kw @ $0.08 in step with kwh the fee is approximately $0.04 in step with hour to have the three components on.
