How to make students consciously turn off the fans and lights, urgent!!

You put a post on the switch, please save electricity, many areas still don't need electricity.

This problem is similar to the public morality competition advertised by CCTV bus giving up the seat class.

As a student, I consume, I enjoy, can you manage it?

I don't turn on the fan when it's hot, you want to heat me to death, and if it's cold, I'll turn it off.

I'm afraid of the dark, I turn on the light and sleep to care about you.

Do your students also use fans in winter?

Let them develop a good habit of turning off the lights when they don't need them, turning off the fans when they don't need them, and holding a few classes on environmental protection and resource conservation, so that they realize that saving resources is not a mandatory indoctrination for you.

If I was a very young child, I wouldn't know what to do

This is more difficult, because there is no exact stake with oneself, and many times it becomes a nossy affair that no one cares about, relying on self-consciousness? This is not very feasible, it is best to have a supervision mechanism, for example, the last to leave, put a notepad, who left the last to register the name, in a strict way is to prevent the last to leave not registered, then the penultimate leave should also register the name, then, after all, there is supervision, for a long time, it will naturally be more concerned about closing electrical equipment and closing doors and windows.

The above proposition is the method used by my laboratory management, I hope it will be helpful to you!

And they talk about electricity billing...

How much more money does it cost to waste one kilowatt-hour electric kiln...

It is estimated that it is a motherboard problem, and see if there are several large capacitors near the power connector that are deformed or burst. Upstairs may not have seen what he meant, he is an onboard graphics card, and there is no contact problem with the graphics card. However, your expression is not very clear, under normal circumstances, we can judge the computer failure can be determined by the prompt sound of the boot.

And you probably haven't heard any sound in your situation, right? Only the power indicator is on, right? It means that the power supply is normal, then it is a problem with the motherboard or CPU, and you can turn on the computer after unplugging the power supply and so on, then I can basically rule out the problem of poor CPU contact.

The most likely scenario is the motherboard capacitor.

You'd better have it checked by a professional.

You can't express it clearly, do you mean that the computer screen is turned off, and then there is an abnormal situation, and other hardware is also turned off? If so, it means that there is a problem with your computer, and it is recommended to repair it.

This happens when the temperature is too high. Turn on the computer to see the system temperature and CPU temperature. Look in the bios.

That's standby, to help you save power.

The power supply is more likely, and it is not excluded to switch the motherboard.

Check the power supply and power cord to see if there is a problem here.

The voltage is too low because summer is the peak period for electricity consumption. You can use it again at another time.

Aging lines. The line current is large. The wires can't stand it.

This statement is wrong, if it is an incandescent lamp, the moment the lamp is turned on because the filament is cold, the filament resistance is low, there will be a large current, but this current lasts for a short time, because as the filament heats up, the resistance rises, and the current quickly stabilizes at the rated current of the filament, and the large current at the moment of turning on the lamp is too short because the time is too short, there will never be a power to turn on the lamp for a few hours. If it is a fluorescent lamp, because a high voltage will be generated when the lamp is turned on, so that the fluorescent lamp can be ignited smoothly, the high voltage has an impact on the fluorescent lamp, and the fluorescent lamp is often switched on and off frequently, which will affect the life of the fluorescent tube, but it will not waste a few hours of power when it is switched on and off once. At the same time, the fan will not waste much power if it is turned on and off frequently.

It may be that the motherboard has been used for too long and aging, resulting in individual parts affecting the power supply of the motherboard, so it is recommended to go to a professional repair shop to repair it.

According to the phenomenon you described, it should be the motherboard but the memory, replace the memory module and try it!

1.Clean the gold finger with alcohol and try to reinstall it;

2.Check whether the motherboard is short-circuited to the chassis;

3.whether the power of the power supply is sufficient;

4.The motherboard is faulty and damaged.

That means the computer can't be turned off.

Remove the motherboard battery and discharge it. Put it on again. Try it.

If it doesn't work. It is recommended to take it to the repair station to have it tested. It may be a hardware issue.

Mine too, it was like this the other day, reworked the system.

Basically, it's good.,Occasionally, when the shutdown point is slow, it will appear.,Depressed.。

Take a look at the settings in the power management, the power usage scheme, or hibernation, it may be set to press the power switch to sleep.

It is recommended to focus on checking the host power supply.

Many cheap power supplies may have incorrect power-on level signal output due to design materials and other reasons, resulting in the failure to switch on and off normally.

Of course, the questioner's question cannot be generalized. The same malfunction of a computer can lead to a variety of reasons. If you encounter a problem, determine whether it is a hardware problem or a software problem.

Generally, it involves the error of individual software or programs, and the software is more likely to crash when running a specific program.

If the boot fails to boot up (no display), the boot POST fails, and some obvious hardware problems (keyboard and mouse failure, blurry display color cast, etc.), it is a hardware failure.

Only by judging the type of fault can we solve the problem more effectively. The person asking the question wishes to let us know more before asking the question.

Unplug the power cord and wait 1 minute to plug it in.
