Low voltage at home! What should I do if the computer is automatically shut down

It's better to use a UPS, which is good for computer hardware, because frequent power outages will break the hard disk, and other hardware will also reduce the lifespan.

Personally, I recommend using a UPS

To buy a voltage regulator, it is better to replace the power supply on the computer.

The rated input of the general power supply is 200V 240V.

Unlike ordinary power supplies, their voltage input can also be at 150V, and even 110V low voltage can be intelligently transformed to the computer.

If anyone around you knows electrical knowledge, you can ask him to modify your power supply for you, install a voltmeter on top of the power supply, and then install a large rheostat with what components, and manually adjust the rheostat at any time to keep the voltage input into the computer standard.

A bad voltage regulator can damage the computer, and the good ones are a little expensive. I use the power supply of the wide-format king, and the line of the led display on it can also be used when I connect it to the cat.

I think the regulator can be a little ......

With a voltage regulator....Is your home in the suburbs?

If it is determined that the voltage is low and the power is automatically shut down, you can consider changing to a host power supply with a higher rated power.

It is normal for the home computer to automatically shut down when the voltage is low, usually the working voltage of the computer power supply is in the working range of 200-240 volts, and when the input voltage is out of the range, it will not work normally.

The solutions are:

1. Buy a computer power supply with a broadband voltage start.

2. Buy a household stabilized power supply.

3. Buy a UPS power supply.

The low voltage has nothing to do with the computer, please find the power supply company or the community property.

It's not a good idea to solve the problem of low voltage on your own; It is useful when the voltage is a little lower, but if your voltage is so low that the computer shuts down too much below the rated voltage, any technical measures will not have a good effect; Besides, low voltage is not your problem, everyone uses AC voltage regulators can only reduce the overall voltage quality, and the power supply company is the most perfect solution.

There are two ways to do this:

1. Purchase stabilized power supply, the cost is low, but the power failure does not work.

2. The cost of buying UPS is relatively high, but the power can be renewed in a power outage, and the computer can still be used.

The voltage is low at noon and evening in the summer, indicating that people turn on the air conditioner to pull the voltage down.

There is another way,You said that the refrigerator、TV is not affected,You can change the power supply of the computer,Change to a wide input voltage range,That is, *** point。 The same solves the problem.

The computer power supply generally has a protection circuit, and automatic shutdown is also the reason for its automatic protection. Generally, the interval between power and off should be more than one minute, and the machine should not be turned on and off frequently, so as not to affect the life of the computer.

The computer will automatically shut down due to low voltage, and the reboot will be slower after shutdown, what is the reason: because the low-voltage shutdown is a mandatory abnormal shutdown, some programs have not yet been shut down, and then the boot requires the system self-test to automatically repair, so it will be slow.

Some ways to solve the problem of automatic shutdown of the computer caused by low voltage: Method 1: If your working environment and mains voltage are low, the computer will always shut down automatically, it is recommended that you buy a voltage regulator; Method 2:

Change the power supply of the computer, preferably with an external interface, which can supply power to the cat or router.

The working range of computer voltage is generally between AC 180V-240V, and the voltage is too low and too high to cause the host to restart or automatically shut down. Multiple reboots or shutdowns can cause data loss and damage to the hard drive and display. The solution is:

1. Find the municipal power department to deal with it and make it supply power normally.

2. Buy a stabilized power supply. Shante 500W regulated power supply regulator can reach 130V-260V, which can adapt to the power supply environment of any city.

3. Replace the wide power supply for the main engine, such as Huntkey wide width, which can work in a 90-270V environment. At the same time, buy a switching power adapter with the same voltage and current not less than the original power supply for the cat, which can work in a 100-240V environment, which is also enough. The two add up to be more expensive than buying Shante 500W regulated power supply.

Damage the motherboard of the computer, and it may also activate the computer's protection system and cause the computer to fail to boot normally.

If it's turned off, it's better, the computer is not high-tech anymore, not as fragile as they say.

By the way, how do you know that the voltage is low and you have measured? Less than 220?

Could it be that the power supply on the computer is broken due to thunder and other reasons?

If the system is not toxic, it may be that the heat dissipation of the power supply, CPU, memory, graphics card, and motherboard is not good.

Use an eraser to erase the gold finger of the memory module and graphics card, and replace it if it doesn't work. Clean the motherboard and plug and unplug parts.

It is recommended to change the fan and power supply.

The hazard is that it causes the machine to age faster.

Insufficient power supply can damage the life of other hardware, such as motherboards, hard drives, graphics cards, etc.

If you live where the power supply has been unstable, it is recommended that you buy a power regulator, about 150 or so.
