Why can't you turn off Windows with the power button on the system unit or on the laptop? Do I need to keep my laptop plugged in. Is it worth leaving the laptop plugged in all the time If you leave the laptop plugged in

If you have reached this page, then you are probably tormented by such a question - how often can you turn off the laptop or turn it on, and in general, how it will be better for the laptop itself so that it serves you for a long time.

I think that I will tell you in this matter, I myself was the owner of a laptop at one time (now I gave it to my mother), but my advice is suitable for both a regular computer and a laptop.

So, in fact, many users mistakenly think that the more often I turn off the computer, the better it will be for it (the less it works, it will last a long time, it really sounds very convincing). Actually it is not. Let's think about what happens when you turn on the laptop?

When we turn on a laptop, firstly all devices receive energy, that is, an electric current. If the device used to receive actually zero electric current, now it instantly receives as much as it should at once. Why am I doing this? To the fact that when you turn on the laptop, all devices receive a little stress in a sense (this is especially critical for the hard drive).

That is, it may not be a completely correct comparison, but it's like a car that immediately starts at full power - the tires then wear out a little, but this is so, a rough example.

Then Windows boots up. By the way, another interesting confirmation that, in a sense, devices get stressed - when you turn on a laptop or computer, the temperature of the processor is slightly or significantly higher than that at which you work on a laptop or PC (you can check it yourself).

So what's the conclusion? If you want to leave for ten minutes or even two hours, then it would be ideal to minimize all programs, or close those that are actively working and leave the laptop turned on. The system can even put it into standby mode or hibernation mode (not to be confused with the usual sleep mode that was in XP), and interestingly, neither the first nor the second completely shuts down the computer.

Finally, I’ll write this - one turning on the computer is equal to eight hours of its operation, I read it somewhere and remembered it, I won’t say that this is true, but there is a share (there was a time I studied the opinions of experts on the Internet for a long time).

Do you have your laptop plugged in all the time? How bad is that for the battery?

How does the battery feel if the laptop is constantly plugged in? I had heard a lot of advice on this topic before, but I could not even imagine that everything was so serious! Why am I at all ... The other day they brought me a laptop for cleaning, an old Acer (about 3 years old). Having dismantled it, by the amount of dust, I determined how clean the owners were. There was practically no dust in it, only on the cooler blades.

After cleaning it from the inside, I reassembled it and turned it on. The battery level showed the remaining 3 hours of operation. Well, well, I think, in about twenty minutes it will squeak about the discharge of the battery. And what do you think? I was cleaning the system for a little more than 2 hours, after which the battery charge remained 20%!

Not believing my eyes, I called the owner of the laptop and asked if he changed the battery, to which I received a negative answer. In my practice, this is the first laptop that, after so many years, holds a charge as if only from a store!

It turns out the secret is simple! The guy (the owner of the laptop), apparently very meticulous, after buying a laptop, he carefully read the instructions, which clearly stated that You don't have to keep your laptop plugged in all the time..

The whole point is that a battery that is constantly connected to power is not discharged by more than 80%, this causes its capacity to be lost. Also, high temperatures have a very negative effect. Don't let your laptop battery overheat.

How to extend battery life

1. Do not keep the laptop connected to the mains at all times. As I wrote above, this negatively affects its capacity. After charging the battery, unplug the power supply from the mains. Connect only when discharged up to 10-15%.

2. Do not allow the battery to overheat. This applies to both external factors (direct sunlight, hot rooms, blocked air intakes) and internal factors (overheating of internal elements, clogged air intakes, malfunction of the cooling system).

3. Once every 10-15 days, do a full discharge-charge cycle. In order to maintain the capacity of the battery, you just need to perform a complete discharge, followed by charging. In the interval between the cycle, you can not charge up to 100%, and discharge up to 40% or more.

4. If you are using your laptop as a desktop computer, the best option is to remove the battery from the laptop and keep it plugged in at all times. The main condition is not to store the battery fully charged.For long term storage, leave battery charge

at the level of 50-60%.

Also an important factor is, if for some reason, the original power supply is out of order, buy the original one! It will cost more than a Chinese fake, but your battery will thank you.

These seemingly simple tips will help you avoid big problems when, at the most inopportune moment, your laptop cannot be offline.

Without batteries, no electronics will work - from laptops to ordinary MP3 players. In recent years, lithium-ion batteries, designated Li-Ion, have become the most common. With a large capacity, they have a relatively small weight. Their only drawback is the need to follow some rules.

Should I leave my laptop plugged in all the time?

For example, you need to know how to properly charge a laptop so as not to ruin the battery by dramatically lowering its capacity.

Make sure your computer is indeed equipped with a lithium-ion battery. You can find out from the user manual, as well as simply pulling it out of the laptop and reading its characteristics. If the abbreviation Li-Ion is found there, then everything is in order.

Most often, portable computers are sold with partially charged, or even completely discharged batteries. And you should know exactly how to charge a laptop for the first time. Therefore, read the instructions below and calmly get to work.

Without turning on the PC, plug the charger into the socket. For the first time, it is better to put it to charge for 6-8 hours. In this case, you will definitely get a battery that is charged to 100 percent capacity. If you charge the included PC, then after 15-20 minutes the icon will show a full charge - of course, this is a small mistake. In this case, you can turn off the computer, remove the battery, and wait a few seconds. After that, put the battery back in place and continue charging while the computer is turned off. Don't be surprised if your laptop gets very hot while charging.

If you want the battery of your device to have maximum capacity (and therefore allow you to work without recharging for as long as possible), you need to “train” it. To do this, when the battery is fully charged in 6-8 hours, disconnect the power supply and start working offline. When the battery is completely dead, put the PC on charge again, preferably overnight. By repeating this cycle 3-4 times, you will be able to develop the battery to the maximum - now it will reach its maximum capacity and will keep it for a long time.

Please note that in the first few weeks of operation, the battery may charge and discharge much faster than indicated in the specifications. Therefore, constantly monitor the indicators so as not to lose important data for you. Also, do not grab a laptop and run to a computer store, blaming the sellers for selling you a low-quality product. After a few weeks of operation, if you properly charged and discharged the battery, everything will return to normal. And now the laptop will surely become your faithful companion on any trip for a long time.

For many users, the laptop is used as a home computer and therefore is constantly connected to the network. Since in this case the battery is actually continuously recharged from the network, the question of how such a mode of use will affect the battery life is quite relevant.

Is it possible to keep a laptop constantly on charge

It is generally known that the number of charge/discharge cycles is limited for any type of battery. Accordingly, the more often the battery is recharged, the, theoretically, the duration of its use will be less.

In practice, battery life is reduced to a greater extent from irregular use due to self-discharge of the batteries. With regular use, even in the mode of frequent recharging, a significant decrease in battery life will not be observed.

At the same time, in order to prevent premature failure of the battery with a certain frequency (at least once a month, preferably once a week), it is necessary to “shape” the battery.

7 rules for using a laptop battery

To do this, disconnect the computer from the network and wait for the system signal to connect the charger. The fact is that the battery management subsystem determines the residual charge based on the availability of information about the average duration of work. If you keep the laptop constantly on charge, then this system will have incorrect data (assuming that since the intervals between the end of the previous and the beginning of the next charge cycle are small, the battery capacity is small) and require connection to the charger more often than necessary.

In most laptop models, battery charging starts when the battery level drops below 95%. Thus, battery charge cycles are repeated quite often.

It is also worth knowing that the batteries used on modern laptops do not actually have a “memory” effect, that is, when the battery is charged until it reaches full discharge, there will be no decrease in battery capacity.

Some more users are interested in the question of whether to turn off the battery in a laptop. In this case, we can say that, given the degree of integration of the battery into the laptop's power system, turning it off can lead to failure of most of the device's components due to a violation of the supply voltage level.

Given the above facts, let's try to decide whether it is possible to keep the laptop constantly on charge.

Since the laptop battery is an integral part of the device's power system, it is absolutely impossible to remove it. Thanks to the device of the laptop power system, the battery acts as an uninterruptible power supply, protecting the computer from power surges.

According to most opinions, if you keep the laptop constantly on charge, then there will be no significant decrease in battery life. The main thing is not to forget to periodically bring the battery to full discharge.

Do I need to disconnect the laptop battery when working at home from the mains?

It all depends on what type of battery you have in your laptop. In modern laptop batteries, there is no such thing as battery memory! The most important thing is not to plant the battery to the very end and not leave it in a discharged state for a long time.

But if you delve into the details of electrical engineering, then there is a microcircuit inside the battery, which, together with the controller in the laptop itself, determines when the discharge threshold is reached and then turns on charging! Accordingly, if your battery is charged, the charge current does not flow to it, which means that the charging cycle has not started. And if you take the way power is supplied to the power grids now, then the battery serves as a kind of UPS (uninterruptible power supply) in the laptop and, during a power surge, stabilizes the voltage due to the battery, which at that moment will be like a large capacitor! So there is no reason to remove the battery in my opinion.

"Bad advice" from experienced?

What can be said about such advice?

Thirdly, the laptop battery acts as an uninterruptible power supply when the mains voltage fails, the laptop switches to battery power, which prevents the loss of your data and nerve cells!

What is the "memory effect"

The “memory effect” is that the battery “remembers” how much energy it gave off per discharge cycle and “thinks” that its full capacity is equal to the amount of energy given off.

Learn how to properly charge your laptop

Therefore, when charging an incompletely discharged battery, it will store less energy than it needs.

Is a laptop without a battery no longer a laptop, or is it still a laptop?

Of course, according to statistics, laptops are up to 95% of the time running on mains power. And, if you use a laptop as a stationary personal computer, and the power grid is working smoothly, you can painlessly remove the battery and work without it.

By the way, many companies have been producing batteryless laptops for a long time, which are in stable demand among buyers (the prices for these laptops are naturally lower than for classic battery ones): for example, PCG-F610 from Sony, DeskNote (i-Buddie) from Elitegroup. The Taiwanese company ASUSTeK, convinced of the undoubted success of batteryless laptops, also intends to enter this market.

What is the battery life of a laptop?

According to statistics, the average life of a laptop battery is 2-3 years (while the average life of a laptop is 6-7 years).

Notebook battery life depends on many conditions: battery type, capacity, operating conditions, etc.

1. It is advisable to subject a new laptop battery 3-5 times to the so-called training (full charge - full discharge - full charge).

2. When buying a laptop (especially through online stores) - if you need a classic laptop (with a battery) - pay attention to its technical characteristics - the "design" absence of a battery is always emphasized.

3. If your laptop provides for battery calibration using the BIOS Setup utility, be sure to use it.

4. If your laptop has a Nickel-Cadmium (Ni-Cd) or Nickel-Metal Hydride (Ni-MH) battery, to eliminate / prevent the "memory effect" once a month, conduct a training cycle "full discharge - full charge".

5. Notebook batteries are designed to operate at room temperature, the allowable range is from +10°C to +35°C.

6. Do not store Li-ion batteries completely discharged.

7. Do not buy Li-ion batteries in reserve.

8. Laptop battery life is about 3 hours.

Laptop: to disconnect the battery or not?

"Bad advice" from experienced?

Quite often, "experienced laptop users" are advised to remove the battery when the laptop is running for a long time from a reliable mains: supposedly, when the laptop is running from the mains, the battery is constantly recharged, which causes a significant reduction in its service life ...

What can be said about such advice?

First, the laptop battery begins to recharge, usually when its capacity drops below 95% (the specific level of allowable discharge depends on the laptop model).

Secondly, the battery is designed to work with alternating multiple charge-discharge cycles.

Thirdly, the laptop battery acts as an uninterruptible power supply (see How to choose a UPS and is it possible to do without it?): when the mains voltage fails, the laptop switches to battery power, which prevents the loss of your data and nerve cells!

Fourth, when the battery is constantly connected to the laptop, it is in "always on alert", i.e. constantly charged, which ensures mobility of work without unnecessary gestures. If the battery is disconnected from the laptop, then before autonomous work (for example, before a business trip), you will have to connect it to the laptop and spend some time (which is always not enough!) To charge, because. Every battery is subject to self-discharge to some extent.

Fifth, if you often work offline on a laptop, then such advice looks at least silly.

All of the above is true for lithium-ion (Li-ion) batteries, which are equipped with almost all modern laptop models. There is no “memory effect” in Li-ion batteries, so they can be “recharged”, i.e. charge without being completely discharged.

What is the "memory effect"

The “memory effect” is that the battery “remembers” how much energy it gave off per discharge cycle and “thinks” that its full capacity is equal to the amount of energy given off. Therefore, when charging an incompletely discharged battery, it will store less energy than it needs.

The “memory effect” is more prone to nickel-cadmium (Ni-Cd), to a lesser extent - nickel-metal hydride (Ni-MH) batteries.

Should I unplug my laptop from power when it is fully charged?

Guest | 04.04., 00:08:16

I am a student, I live in a hostel, so as a stationary computer I have (like almost everyone) a laptop.

So, should it be turned off when it is fully charged or should it not be done too often? The instructions say that the battery is designed for 300 charges / discharges. but if after each charge it is turned off, then the battery can be destroyed in a month.

I have Sony FW. The battery care function is enabled. The battery has degraded. Recently, for fun, I decided to try to work from the battery, I was unpleasantly surprised by its degraded performance.

What is the power button for? Of course, in order to quickly and without unnecessary movements turn off the device. This can be done with a video camera, light bulb, printer and other electronic and household appliances.

On the system unit of a computer or on a laptop there is also a power button - “power” (literally “power”). Then why does a computer or laptop need to be turned off programmatically through a command in the menu, and not by simply pressing the power button?

How to shut down a Windows 10 computer programmatically

This will take three clicks:

1. Press the Windows main menu button (1 in Fig. 1).
2. Select the "Shutdown" command (2 in Fig. 1).
3. Click "Shutdown" (3 in Fig. 1). In this mode, the computer does not consume electricity, you can turn off the plug from the outlet, if it is important for you.

Rice. 1. Proper shutdown of Windows 10

The above procedure for shutting down Windows 10 is, of course, different from simply pressing the power off button found on a computer system unit or laptop.

It should be noted that it was in Windows 10 that it became possible to turn off the computer using the power button:

But in earlier versions of Windows 7, 8.1, Vista, XP, there was no such way to turn off the PC.

It may seem to a simple user in general that there is no difference in how to turn off the computer - programmatically or using the power button. After all, in the end the result is the same: the computer turns off. Proper shutdown of the Windows system takes from 20-30 seconds to one minute, while shutting down the computer can be many times faster by holding the power button for a few seconds.

Is this a good idea? To answer this question, you need to know what happens to the computer during the standard Windows shutdown procedure.

How Windows works before shutdown and during a standard shutdown

When the computer is running:

• the hard drive makes thousands of revolutions per minute;
• the read head moves along the surface of the disk;
• Windows accesses, reads, modifies and deletes files;
• Windows accesses the system registry and makes changes to it.

During a normal shutdown (via the appropriate menu command):

• Windows saves files that were accessed. Certain programs, having received a message from the operating system, display a prompt for the user to save the changes;
• Windows closes access to the system registry;
• the disk's read head is parked in the correct position for the disk to turn off later, and the disk's rotational speed is reduced to a complete stop.

Usually, those processes that occur when you turn off the computer using a command like "Shutdown" take no more than a minute. And holding the power button for a few seconds turns off the computer instantly. But, alas, with such a “quick” shutdown, no actions are performed before the normal shutdown of the PC.

What are the scale of the consequences of a non-standard shutdown?

Any files that have been opened in Windows may become corrupted or not saved at all due to the fact that the system did not have time to finish working with them. After that, one of the programs will refuse to run due to a critical error in a damaged file, and it is likely that you will have to reinstall either this program (file), or even the entire system.

Data in the system registry may also be corrupted. This can lead to critical errors of the entire system, the only solution to the problem will be a complete reinstallation of the operating system.

Due to the sudden stop of the head, the surface of the hard disk may be scratched. And this, in turn, leads to a number of consequences: system freezes, problems with programs, new disk damage, etc.

A few times you may be lucky, and damage will occur in those areas of the disk or with those files that the system does not work with. But one day (perhaps this will be the day when you need to do urgent work) you will find that one of the programs gives a message about file corruption or missing library.

You contact, he will say that the hard drive has worn out to such an extent that it will have to be replaced, while you will lose your precious photo archive and a bunch of important documents. Especially if you didn't take care of it in time.

What to do if the computer freezes and does not respond to anything?

If the computer freezes, does not turn on for several minutes, the image on the screen is frozen, the mouse pointer does not move, does not open using the Ctrl + Alt + Del key combination, then something has clearly gone wrong in the system.

Even when using a normally functioning computer, this can happen - but very rarely. Indeed, in such a situation, there is no other alternative than to press and hold the power button until the computer (or laptop) is completely turned off.

On subsequent downloads, you may be prompted for errors. Do not skip this step, let the system try to fix problems caused by a sudden power outage on its own.

If possible, check the system log for error messages that may indicate the cause of the hang. Repeated lags (errors) are a sign that there are serious problems with the computer.

Not all laptop owners know how to properly turn off the device. Many of them believe that it is enough to close the lid. But it's not! This article will discuss how to turn off a laptop with any operating systems and under different circumstances.

Not everyone knows that after closing the lid, the laptop will turn on. But in order to completely turn it off, this is not enough. It is important to save information and not lose the work process, and for this you need to know how to turn off the laptop correctly. Even a child can figure it out.

How to turn off laptop. The easy way

Any computer user is undoubtedly aware of such elementary things as shutting down. Turning off the laptop is no different from To do this, just click the "Start" button in the left corner of the screen and select the "Shut down" item.

In Windows XP and Windows 7 operating systems, this process is the same:

1. First you need to close all programs and windows, as well as turn off USB devices such as speakers, scanners, printers, etc. Free up the drive and remove the flash drives.
2. After that, you can click the "Start" button and click "Shut down".
3. After the screen goes blank and the laptop stops making noise, you can close the lid.

How to turn off a laptop in Windows 8. Several ways

So, with Windows 7, everything is very clear. But many laptop users with new operating systems are confused because the familiar Start button is simply missing in its place. And the interface of the system is significantly different from previous versions.

There are about a dozen different ways to turn off a laptop in Windows 8.1. The easiest of them is to open a hidden panel by moving the mouse cursor to the right side of the monitor. Then select "Shutdown" and "Shut down". You should know that this panel also opens by pressing the Win + I keys. This method is standard, and for advanced users it may seem boring.

Another method is to turn off through the lock screen. This is necessary when the user has started the laptop and realized that at the moment he is not going to work on it. There is nothing complicated in this shutdown method, since it is identical to the previous one. You should press the shutdown button and select the desired action. The lock screen can be called up by pressing Win + L on the keyboard.

Lesser Known Ways to Shut Down a Laptop

Windows developers have worked hard to ensure that users have many options for how to turn off a laptop.

Briefly about those methods that are unknown to many computer scientists:

• Shutdown with Alt+F4 keys. When you press this combination, a system update window will appear prompting you to shut down.
• Shutdown through the command line, which is opened by pressing the Win + R keys. In the window that appears, write the command shutdown / s.
• Shutdown using the additional Start menu, which can be called up by pressing the Win + X keys. Further, as in the standard method, it remains to select the desired items.
• Scheduled laptop shutdown. The method is quite simple and it will not be difficult even for a beginner to understand it. In order to daily at the same time (for example, at 00:00), you need to call the command line (Win + R) and enter the following command:

Schtasks.exe /Create/RL Highest/TN Shutdown/SC Daily/ST 23:57/TR "%WINDIR%\system32\shutdown.exe /s/t 180/c.

Here the number 180 indicates the seconds before shutdown. In this case, 3 minutes (180 seconds) is set.

To stop the schedule, the following phrase is entered into the command line: shutdown /a. This command cancels the shutdown schedule.

• Turning off the laptop through a shortcut. What is it and how to create, every user knows. The shortcut can be placed in a convenient place and when you double-click on it, the gadget will turn off. At the command line, you need to enter shutdown / s / t0, where 0 is the time until shutdown, which can be set at your discretion.

How to turn off the laptop if it freezes?

It happens that during operation the system suddenly stops responding. This may be due to a freezing of a certain program or Windows itself. In this case, you need to try to turn off the laptop through the Ctrl + Alt + Delete combination. This will open a menu with a choice of actions. If the program freezes, then you need to select the task manager and close it. Then switch off in the usual way. If you need to immediately turn off the laptop, then you should select the already familiar "Shutdown" button.

When the system freezes tightly and does not even respond to the above key combination, shutdown is possible in only one way, hard. To do this, hold down the power key for a few seconds and the laptop will turn off.

Turning off a laptop with the latest OS version installed

At the moment, the latest operating system is Windows 10. And most users have already switched to using it. There are no special ways to turn off a laptop on Windows 10. To do this, just use one of the methods described in this article.
