【 Weak current College 】 how to keep your computer in standby power consumption is equal to zero

Use the computer how to saving energy.

For those who frequently use the PC, the PC power consumption has been a matter of concern to the business, General, TV's electricity consumption 80W, PC in about 250-400W. A PC power consumption of each month: If every hour to one day open 300W× 10 hours × 30 days a month = 90 degrees 90KW, that is, this is a conservative estimate. (Monitor power consumption: 15 inch, 17-inch, 19-inch monitor power consumption 80W 60W, respectively, of about 100W).

The computer is in sleep state, power consumption is about 7.5W, inexplicably in WindowsXP entered standby power consumption was reached 51.48W! description motherboard at this point in order to protect the data, but also in the consumption of electricity not small; even turned off the machine, as long as you haven't pulled the plug, energy consumption, just the computer has approximately 4.81W! like remote controls and intelligent switches, etc. in the let it more smoothly and electrical equipment, but also to electrical additional extra energy consumption — standby power consumption.

Often you can see some of the family or units equipped with anti-glare monitor, was originally intended to reduce the electromagnetic radiation of the monitor on the human body, in fact, this is a misunderstanding. Test certificate, anti-glare protection against electromagnetic radiation and not much effect, on the contrary, after installing will cause the image brightness decrease, in order to get the perfect image, the user will also increase the brightness of the display of load, causing electromagnetic radiation not drop back up, and increases power consumption, it is not worth the candle. So, has passed the certification of TCO series monitors can be assured, there is no need to install anti-glare.

Here are some energy-saving energy-saving proposals and measures

1. suspended computer, if you expect the pause time is less than 1 hour, it is recommended that the computer on standby, if the pause time is greater than 1 hour, it is best to completely shut down.

2, usually used when you want to shutdown the computer, you should unplug or turn off the power switch on the power strip and gradually develop the habit of total power loss, but don't let it is powered on.

3. unused peripherals like printers, speakers, and other time off. (The speaker is the large power consumption)

4, like CD/DVD drive, floppy drives, network cards, sound cards and unused devices in shielded in the BIOS. (Power consumption does not decrease too much longer to see also extend the service life of the equipment)

5, use the CPU cooling software.

6, lower display brightness. In text editing, some background to Dim, energy-efficient while protective eye sight, alleviate fatigue strength. When the computer is playing music, storytelling, stories, and so a single audio file, you can completely turn off the monitor.

7. many DIY were keen on overclocking. As the technology of fine, if not overclocked as capable of satisfying performance needs, or as few overclocked, both energy security and stable also.

In the standby state, device did not cut off the power supply, also failed to run the main functions, appears to be shut down, in fact there are fewer parts within the electrical circuits and components in electrical work, this state of standby power consumption is.

First of all, is the concept of the problem.

You can see that all people who didn't miss a closed the tap water that is a waste of resources, waste of money.

All the people saw the place does not need lighting during the day with a lamp that is a waste of resources, waste of money. While the PC shutdown of power but nobody knows, because it is invisible. Only instrument to measure. Often the vast majority of PC owners believe that: the computer since the shutdown, how will the computer shutdown power?: no, no, no power after? was also expressed that the computer is in a shutdown state, power is just a little bit, no fussing. This happens to people misunderstanding of cognition.

Secondly, the lack of attention. The reason is not the right idea.

As everyone knows, the computer is in a shutdown state, is an electro-mice, continues to steal electricity. Standby loss is usually refers to our most common-powered power also connect the motherboard, monitor, printer, router ADSL network Terminal, etc., in which case you would also like to + 5Vsb continued to Board, keyboard, mouse, and other devices continue to supply, at which point its standby power consumption to around 5W. Click on system shutdown, computer, monitor and computer peripherals (printers, scanners, ADSL network Terminal, routers, etc.) are still in power.

PC standby power consumption test: (multimeter model MS8215 MASTECH?)

Criteria: in a computer is not turned on

Test equipment for computer host 17 "flat screen monitors,

Results: the power consumption of power to instantly 176 w

2 seconds after continuous standby power consumption is 13.7 Watts

Today, computers have become indispensable in modern office help, is standing for learning and entertainment tool, but many people still do not know the computer misuse will result in large energy waste.

Assuming the authorities, units each computer work 6 hours a day, 2 hours, stand-off 16 hours, according to the current amount of our computers have 5299 million units to calculate the annual power consumption of only shutdown state a can save 6.2 billion kWh of electricity.

3. a majority of operators to focus on the customer's Internet environment and service levels, often overlooked power consumption costs. power consumption can be said to be one of the major cost-how to reduce power consumption, improve the operator's profit? of course, the less the better power consumption.

4. computer shutdown state, not actually disconnect the electricalSources of harm:

1. According to the authoritative Department statistics:

● Computer host home electronic products topped the lowest energy consumption

¡ÑThe computer energy-saving equipment each year saving $ 500 degrees

● My current computer ownership nearly five thousand and three million units

• Government sector energy expenditure exceeding 80 billion a year

2. in addition to the computer on standby power consumption, resulting in unnecessary waste of energy;

3. long power will make the electrical equipment is in a State of fever, thus shortening the life of electrical equipment;

4. in the face of natural disasters, such as: Thunder and lightning will along the wire when (or cable) striking appliances.

5. being a guest computer, its power is normal. The idle power consumption of the computer is also properly? answer must be in the negative.

The authors investigated many computer owners, their view is that there is a little bit of power consumption. These computer owners scale most in more than 300. This serves to show them in this regard is a blind spot. You can also say that they haven't the operating costs of the concept of energy saving.

Investigation of these Internet operator attendance up to 80% full time only 1 ~ 2 times. The authors on their own computer (only host and monitor different) test result: computer shutdown of electricity consumption 13.7 Watts. This is just one of the domestic use of computers, you imagine if this 300 computer without guests of power consumption will be? 300 * 13 = 3900 Watts, that is one hour of electricity consumed 3.9. Equivalent tariff: 3.4125 element. For attendance is not too high in terms of the Internet, I'm afraid that after 10 pm the following day at 10 a.m. time period guests blank opportunities. Then shut down power consumption: 300 * 13 * 12 = 46800 Watts: 46.8 kW, according to the General algorithm: a kilowatt hour of electricity consumed at one time. Then one day electricity consumption: 46.8 degrees about us electricity charges: 46.8 * 0.875 Yuan/degree-= $ 40.95 pay electricity bills each month: 40.95 * 30 = $ 1228.5. Payment of electricity per year: 1228.5 * 12 = $ 14742.00

Do not know. Attendance is dynamic, and may in fact than the above computed value or high point or low point. The above algorithm is normal.

How to keep your computer in standby power consumption is equal to zero

To do so in the normal use of the computer, the computer is idle power consumption to zero is not difficult, Taobao called "computer power saving zero power consumption in standby Po pc-powersaver control unit" by the computer operator control: the computer out of use, click on system shutdown, power off automatically with the commercial power supply, power consumption is zero, instead of approaching and zero-power-on time by the computer's operation, press the power on key on the host, you can normally use the computer. And the usual computer operation is no different. Mainly computer owners are willing to do it.
