How many hours can a laptop be used when disconnected from AC power 5

It can be used for about 2-3 hours, it depends on the quality of your battery, but sometimes the power displayed by the system is not particularly accurate, it is best to start charging when you see the remaining 15 minutes... Good for the battery! ~

And now it is generally a lithium battery, so you don't need to charge it for 12 hours when you use it for the first time, or it's not good for the battery.

It's because the first three times I used electricity to charge it to the limit, so the battery life is relatively short now!

Hope it will be useful to you!

It's not very good to do that.

In order to prolong the life of the battery, be sure to remove the battery from the machine when using the alternating current to avoid damage to the laptop and the battery.

When the battery is fully charged, the AC input should be disconnected. Because overcharging can overheat the battery and shorten the life of the battery.

Do not charge the battery when it is too cold or too hot, as the appropriate temperature for charging is between 10-30 degrees Celsius.

Regardless of whether your laptop uses lithium or nickel-metal hydride, it is best to avoid the memory effect by recharging it after it is almost completely charged (less than 5 batteries). Lithium-ion batteries also have a certain memory effect, but they are much smaller than nickel-metal hydride batteries. However, it should be noted that when charging, try to avoid too long a time, and generally control it within 12 hours.

The length of a battery's life is determined by the number of times it is charged and discharged. If you always attach the battery to the laptop without removing it, the battery will not remain as fully charged as you would think, even if you turn off the machine and remove it from power. Laptop batteries consume power even when the computer is powered off due to the control circuitry integrated into the battery.

Since the battery starts charging as soon as the AC power is connected, the battery will be charged and discharged repeatedly whenever the power is turned on or off, affecting the battery life.

It is best to unplug the battery when using alternating current, otherwise the battery will be in a hot state for a long time and its life will be affected. If the battery is not used for a long time, please flush and discharge it at least once every two months to ensure its activity. There is also an issue that needs to be taken care of when storing batteries.

At present, the lithium-ion batteries used in the vast majority of notebooks are often prone to over-discharge if they are not used for a long time, and may no longer be able to be charged. To prevent over-discharge, it can be kept in a cool, dry place in a half-charged state, and then charged to half a year again.

Factors that affect battery life also include the temperature of the environment in which it is used, and it is recommended to use it below 30.

<> want. When the computer is not in use, the electricity should be turned off. Because of the destruction of the wax for although the computer is not running, but the auxiliary Yu Hongzhu power supply in the computer has been working, at any time to monitor whether the computer is turned on, so that it also needs to consume electric energy, and the power supply uses switching power supply, the components have been subjected to high voltage, in case the components are damaged, the fuse will be burned, and the heavy silver book will break through the circuit board, and even cause a fire.

Hello, I also use this notebook, because I don't often go out with it, so it has basically become a desktop posture

The battery is unplugged and then directly connected to the device and used like a machine

Powering on for a long time is theoretically harmless to the computer itself and the transformer itself, because the computer itself is an electrical appliance, and electrical appliances have a service life problem.

When the life is up, it is natural that you will have to die, so you don't have to worry about this

However, batteries are different, and if the battery is on the machine for a long time, it will cause a process of micro-discharge and micro-charging to the battery.

Just like an ordinary No. 5 battery, we pinch the positive and negative poles with our two fingers, which is also consuming power

Therefore, the battery should be unplugged, and remember to give the battery a full charge and discharge process every month to improve its service life

Hope mine is helpful to you

Of course, you can, but it will waste power consumption, and turning on the computer for a long time will also accelerate the aging of the computer and accessories, and some equipment, such as hard disks, are also easy to burn out and fail.

Nowadays, because the computer uses the power supply of the ATX principle, when the computer is turned off, if the mains power is not cut off, the auxiliary switching power supply part of the power supply is still working. This should be no problem, but the current quality of the domestic power grid is relatively poor, and many communities may reach a high level of mains power at night, and in some places even the mains voltage will exceed 300V at night. In addition, the protection circuit of the auxiliary switching power supply in the ATX power supply is also relatively simple, if it works at a high mains voltage all night, the auxiliary power supply circuit is very easy to be damaged due to overvoltage, resulting in the entire power supply can not work normally.

Therefore, in order to protect the computer, it is best to cut off the power used by the computer after shutting down.

There is also a long time without using the computer, the coms battery on the motherboard is charged and powered by the motherboard when it is turned on, if it is turned off, the coms battery cannot be charged, and it can only be powered by its own power In this way, when the coms battery is always used up for a long time, even if it is not used up, it will cause the coms voltage to be unstable due to insufficient power, so it is better to turn on the machine at an interval time.

A good power supply can be used for many years, and many units are P3 and P4 old computers, and they are all used for seven or eight years or ten years. Generally, three to five years is a good power supply, the second is not easy to say, I personally recommend using the Great Wall, Huntkey's power quality is still good. FSP's can also be used, and many brand machines use his.

This is taken into account, for example, the environment in use: temperature, humidity, dust, ventilation, etc., etc., all have an impact on the life of the power supply, as well as the use of power, the original components of the motherboard: for example:

The number of hard disks with them, the optical or burning optical drives, etc., and how often they are used. Moreover, it depends on the quality of the power supply itself, some power supplies are finished after less than a year of use, and some have been used for more than 10 years. It's hard to know for sure.

There is also a loss of power supply, and even if you don't use it, it will reduce the lifespan, which is the reason for the internal chemistry.

If you look at the working environment of the computer, if the humidity is high and there is a lot of dust, it may not work for 1 year. If the environment is good, it can be used for 3-10 years.

Hello, I'm glad to reply to you, the reason and method for the computer to lose power once in a few days:1Is there a problem with your power cable, does it lose power every time you move your case, power outlet, or computer desk?

If so, please check the power connection. 2.The voltage in your area is unstable, this can be tested with a multimeter, if the mains power is far lower than 220V when the power is off, please try to use the computer power supply to supply insufficiently, please touch the power supply of the computer case with your hands when the power is off, whether it is very hot, if so, then replace the power supply part of the case.

Overheating protection, whether you are playing a game every time the power is off, it can be operated by animation, if so, please replace the CPU fan. 5. Static electricity interference, whether there is a feeling of electric shock when touching the metal part of the chassis shell with your hands, and showing electricity when measuring with a pen, if so, please ground the chassis. 6. There are poor contact places on the motherboard.

<> want. When the computer is not in use, the electricity should be turned off. Because although the computer is not running, but the auxiliary power supply in the computer has been working, at any time to monitor whether the computer is turned on, so that the same needs to consume electric energy, and the power supply adopts switching power supply, the components have been subjected to high voltage, in case the components are damaged, the fuse will be burned, and the circuit board will be broken down, and even cause fire and disaster.

Extended information: 1. High-quality power supplies generally have multi-national certification marks such as FCC, UL in the United States and the Great Wall of China. These certifications are the certification body according to the technical specifications in the industry for the development of BAI industry standards, including production process, electromagnetic interference, safety protection, etc., where the product meets a certain index in the declaration of certification passed, in order to use the certification mark on the packaging and product surface, has a certain authority.

2. The generator can convert mechanical energy into electrical energy, and the dry battery can convert chemical energy into electrical energy. The generator and the battery itself are not charged, and its two poles have positive and negative source charges, which generate voltage from positive and negative charges (the current is formed by the directional movement of the charge under the action of voltage), and the charge conductor is originally there, and the voltage only needs to be added to generate the current.

Just a few hours a day, the computer will be powered off or not as follows:

1.It's best to cut off the power, just in case.

2.Because the system is in the shutdown state, and does not completely cut off the power supply, the host power supply, the motherboard power supply and the mains power are still connected, once the voltage fluctuation or lightning weather is very easy to cause damage to the motherboard, power supply and various peripherals, for the sake of insurance, it is best to completely cut off the power supply after shutdown.

3.Computers can be turned on in a variety of ways, and these boot methods are often not turned on in ordinary applications, so it makes little sense to keep the computer powered on after shutting down.

4.Unless there is a special application, such as a remote boot, which keeps the computer powered on all the time, it should be good for the computer to unplug or turn off the power outlet.

5.For example, in areas where the power supply is unstable, surge voltages may cause some harm to the computer.

6.Unplugging during a thunderstorm can also reduce the hazards that can be caused.

The following is only about brand goods: the probability of CPU and memory problems is very low, and it will be no problem for 10 or 20 years. The chances of problems with the motherboards of big brands are not great, and depending on the workmanship, it is no problem to use it for 5 or 10 years.

The problem is that both the hard drive and the power supply are consumable parts, especially the hard drive. The stability system has high requirements for power supply, it is recommended to buy a big brand regular power supply, which is sufficient and has good protection for all components. In addition, try not to press the power button to force it off, which will damage the hard disk.

If you want to go without shutting down for a long time, in addition to the excellent power supply, it is necessary to use a "24-hour enterprise hard drive" instead of a regular hard drive.

Some servers don't shut down for ten years.
