You can use your laptop while it is charging. Can I turn off my laptop while charging the battery? Secrets of proper charging

AT recent times various compact mobile electronic devices, allowing you to use all the services and entertainment of the Internet, without being "tied" to a specific place - smartphones, tablets, communicators and, above all, laptops.

Of course, in order for mobile devices to be fully mobile, they must be equipped with their own sources of electricity.

This is especially true for the most energy-consuming mobile devices- laptops. The energy source for almost all modern laptops is lithium-ion batteries.

Lithium-ion batteries have taken over nickel-cadmium batteries, and almost completely conquered the mobile device market due to a number of advantages, including:

• long service life;
• light weight;
• compact size;
• lower cost;
• short charging time;
• longer operating time on a single charge;
• lower price.

However, at the same time, there are certain nuances in the operation of lithium-ion batteries that must be taken into account if we want the laptop to serve us longer without replacing the battery, because the cost of a new battery can reach a third of the cost of an entire mobile computer. So, we find out how to charge a laptop correctly.

Secrets of proper charging

Figuring out how to properly charge a laptop battery was not so easy. There are a lot of opinions on this matter. As you know, everyone knows how to play football, treat any disease and raise other people's children. Nowadays, this list of "general knowledge" can be added to the knowledge of how to charge a laptop battery.

What you just do not have to hear about this, including completely opposite opinions. For example, that the battery should certainly be charged only after it is completely discharged, or, conversely, the battery should never be allowed to discharge below a certain limit. So who do you believe?

It would seem, what is easier, to take and read the instructions from the manufacturer, which necessarily accompanies the product. Only here is the problem - the instructions, as a rule, in this aspect are concise, just obscenely. Sometimes information about charging is limited to the fact that for this the battery must be connected to the mains. Nothing to say, valuable information.

There is reason to believe that this state of affairs is by no means accidental: the income from the sale of components and spare parts can sometimes exceed the profit from the sale of the main product.

For example, one can recall a fact that is not advertised, but by no means a secret: the lion's share of the profits of printer manufacturing companies is not brought by the printers themselves. The maximum profit is derived from the sale of cartridges and consumables.

Of course, the percentage of profit from the sale of batteries relative to the total turnover is not so large, but if we are talking about turnovers in billions, then even fractions of a percent will amount to millions and hundreds of thousands. Since we cannot count on the help of manufacturers, we turn to specialists for help.

1. Before we talk about properly charging a laptop battery, it is necessary to touch on general operating issues. For a lithium-ion battery, the temperature regime is important, the optimum ambient temperature is + 15-25 degrees, the limit is + 5-45 degrees.
2. Under no circumstances should a battery cooled below zero degrees Celsius be used. If a laptop or battery is brought in from the street, be sure to let the device warm up for at least an hour.
3. When using a mobile computer at temperatures of 30 degrees or more, it is advisable to use special stands. In addition to the passive effect of providing an additional path for the cooling air to enter. Such stands can be equipped with an additional battery-powered cooler connected to the device via a USB drive.
4. As to how to produce charging the laptop battery correctly, here, experts are almost unanimous: both those who advise completely discharging the battery and those who suggest keeping the power source constantly charged are equally mistaken.
5. The optimal battery level is 40-80%. Maintaining the charge level within these limits can increase the life of the cell by 3-4 times, up to 1200-1500 full discharge-charge cycles.
6. There are no problems with tracking the lower charge limit, for this it is enough to set up the appropriate notifications. But how to catch the moment when the laptop is 80% charged? After all, even special software that limits the level of charge will be useless if charging takes place in the off state (and this is exactly how it usually happens).
7. There is no single answer to this question. Some people recommend using timers, for example in mobile phone, in order to detect the battery charging time and use these values ​​in the future. Agree, it is also not the most convenient way.
8. In any case, it should be noted that the level of charge and (in particular) the remaining time until the battery is discharged, which the computer “shows” to us, may differ from reality. To clarify the picture, an operation called " battery calibration».
9. To calibrate, it is enough to continuously work on the laptop from the state of the power source " fully charged"To the state" full zero "(Although it's better to stop at 2-3% and complete the work in normal mode). A full charge-discharge cycle once every couple of months will not cause much harm to the battery.
10. This point must be taken into account when starting work with the device. To charge a new laptop properly, place it without turning it on, charging at night. After that, when you turn on the device, 100% of the charge on the screen will be guaranteed to correspond to 100% in the energy storage.
11. You can also use special calibrator programs that, without human intervention, “drive” the computer for a couple of hours and calibrate.

Does this advice make sense at all? After all, the limits of the optimal charge (40-80%) leave the user less than half of the possible operating time of the device, that is, depending on the tasks performed, 1.5-2.5 hours. Is there any point in mobile computer who is capable of being mobile for a couple of hours at best?

Question: ASUS laptop not fully charging

Hello. I am the owner Asus laptop x551mav-sx943b. It started for me recently (I don’t remember personally, but everything was fine about 3 weeks ago). My laptop is not charging more than 89-90%. Even when the laptop is turned off, the charging diode is always on. I tried to start charging and in Linux Mint, but also does not charge more than 89-90%. The laptop is only 9 months old.

Answer: Well, if such a program is worth it, then the laptop will still be on or off, it will not be fully charged

Q: Laptop won't charge

hello.
laptop samsung np350v5c.
charger - ginzzu ga-10120u.

Yesterday, after finishing work, I turned off my laptop.

The next time I tried to turn on the laptop, it would not turn on and the battery indicator was off.

Tried to start by pulling out the battery, but there is no reaction.
other laptops are charging the same memory, what could be the reason?

Answer: Since the power supply unit is working, it is logical that there is a problem with the laptop, since there is no charge indication, it means that either the power supply from the power supply unit does not go where it is needed, the firmware may have flown, there will also be no indication.

Question: How to charge a laptop if the power controller has flown

I dug into the laptop, poked power settings and poked like that. That the battery has stopped charging. I thought it was the charger. I could not immediately check the charging, I checked it after three days, by this time the battery charge was over, and the charging turned out to be working. I think I disabled something in the settings. . But how to deal with it if the laptop is not charging?

P.S. Please don't troll

Question: laptop. only charges when turned off

dell xps 14z (Compal LA-7451P)

Used motherboard came from aliexpress. I immediately flashed the BIOS on A6, on A2 I did not pay attention to how it behaves.

When the OS is loaded (it doesn't matter which one I tried win8.1 and ubuntu), when the power cable is connected, the charging icon (battery filling) blinks for about 20 seconds, writes "connected, charging." then the icon just lights up, at the same level (how many this moment charge), the inscription is the same, the charge does not increase. the battery is not charging or discharging. stands on the same level. turn off the laptop. then the battery is charged.

Three tips from Google did not change the situation.

Answer: oops. started charging. in 15 minutes by 7% (even though the icon does not blink)

Question: DELL laptop not charging

There is Dell laptop vostro 1500/ Flew native PSU, bought a universal one. When connected, a message appears:
"Power Adapter not recognized".
"The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 90W AC adapter or higher for best system operation."

The laptop shows that the power is connected, but the battery is not charging. The bios also states that the charger is not recognized. Used PSU AcmePower ULA-12.

Characteristics of the native power adapter:
90W
Input: 100-240v, 1.5A
Output: 19.5v, 4.62A

Characteristics of a universal PSU:
120W
Input: same
Output: 20v (compatible with 19.5), 5A.

How can I solve the problem with battery charging?

Answer: Specialized
A little background is needed here. If the original adapter did not burn out, but the cord near the connector simply frayed (consider that 19V got on the port), the repair of the mat will help out. boards or "weaned" from the original BIOS adapter.
For advanced - the battery can be charged and not in the laptop.

Question: The laptop does not charge and does not work from the mains (without battery) - Acer Aspire 5720G

Yesterday I was sitting at a laptop and suddenly the brightness dropped to 50%. I looked in the lower right corner, and there is an icon "battery" instead of "charging". The laptop operation indicator is on the left (green, as in the picture), charging is on the right (yellow when charging, green - the battery is charged). The charging indicator is off. Thought the electricity was out.

I look at my digital clock in the room - it works! I checked the cable from the power supply - connected. I decided to turn it off and unplug it. The laptop is off. I connect the charging - the "charging" indicator blinks (always on, not blinking), but there is no dependence on time. Blinking random yellow. It can blink 2 times in a second, or maybe once in 5 seconds ... I heard from a friend that his battery was dead and then he took out the battery and connected directly to the power supply and the laptop was started from the mains. I also pulled out the battery. Connected the power supply. I try to start - does not work. Decided to take a break. An hour later, I inserted the battery, connected it to the power supply - charging went. Launched laptop. Everything is fine. It happened again 2-3 hours later. It's been 12 hours since then and nothing helps. The power supply looks intact. The green indicator on the PSU is on as usual. It feels like something inside the laptop ... The laptop starts up with a battery (which has 3-4 minutes left to charge), but does not want to charge. I do not accept SC and other similar answers. If something needs to be replaced specifically, then write it down. Thank you
You insert the plug, charging takes 10 seconds and stops, the indicators start flashing.
You take out - everything works. That is, the laptop from the battery works stably, as soon as you connect the charging, such a trouble begins. I launched a laptop without a battery on one PSU, everything starts and works, but at any moment it can turn off. Off - charging normally. And I also noticed if you insert charging, start, load Windows and do nothing else - then charging in progress and nothing blinks, but as soon as you start to run programs or open windows - again after 10 seconds. starts...

PSU 90W 19V x 4.74A (measured at the output voltage of 19.45 V)

Battery 4400 mAh wear 57% (holds for about an hour).

Laptop: Acer Aspire 5552G

Answer: Was in the service center.

After the diagnosis, the cause of the breakdown was revealed:

"The contacts of the cable that goes from the charging socket (controller) to motherboard." Because of what they burned, they said it was not connected tightly, because of this, 2 middle contacts + and - broke through, and the extreme ones remained intact. I had to change this wire with contacts and a power socket.

Total: 1 day of work and 1680 rubles for work with details.

Do you know how to properly take care of your laptop battery? Do not keep constantly connected to the outlet? Let the battery discharge to the “red” mark and fully charge it again? The bottom line is that such strategies are actually bad for the laptop battery. It's time to learn how to charge your mobile friend right.

Isidor Buchmann is the CEO of Cadex Electronics. This company is engaged in the development and production of chargers, as well as tools for express testing and diagnostics of batteries, including those for industrial needs. In addition, the company supports the research of Battery University, an educational web-based project aimed at making information about the correct and most efficient use batteries.

In an interview with Wired, Isidor Buchmann spoke about the main and widespread mistake that laptop users make.

You can not charge the laptop battery to 100% of its maximum capacity. Ideally, battery charging should start at 40% charge and stop when the charge reaches 80%.

This greatly extends battery life - more than 4 times in some cases. The reason for this is the principle of operation of lithium-polymer batteries: the voltage in each cell is proportional to the level of charge. A voltage level close to the maximum standard indicator wears out the battery faster, which ultimately leads to a reduction in the number of charge cycles and an accelerated decrease in battery capacity.

Battery University research clearly demonstrates the validity of the statement: when charged to 100%, the battery regularly produces 300-500 cycles, while when charged to 70%, the number of cycles increases to 1200-2000.

Unfortunately, maintaining the correct battery charge amplitude can be extremely difficult. You cannot constantly monitor the battery indicator during operation. Searching for relevant applications for OS X and Windows did not return positive result. Some manufacturers supply laptops with special software that limits the level of charging, but not all do this. The only optimal solution here may be to measure the time required to charge and discharge the battery to the desired level. In the future, time intervals are quite easily monitored using any timer with notifications.

Most modern laptops are equipped with lithium-ion batteries. This battery is lightweight and high power, sufficient to provide many hours offline work device even when using its functions intensively. However, due to its merits, a lithium-ion battery is relatively expensive, so users often ask themselves: how can you extend its service life? One of the most important moments in the "life" of a laptop battery is the process of charging and discharging it for the first time.

• After you have bought a new laptop, you need to fully charge it. Connect the laptop to the network, but do not start the download operating system. Wait until the battery is fully charged - the charge status indicator LEDs located on the side or back of the laptop should turn off. First charge lithium ion battery lasts at least four hours.
• After charging is complete, the laptop can be turned on and started working. In this case, it should not be connected to the network adapter, but the battery should be allowed to completely discharge (at the end of the battery life, take into account possible data loss). This is done so that the power supervisor chip and the operating system driver that manages power capture the real capabilities of your laptop battery and install automatic tuning relevant parameters.
• After the laptop battery is completely discharged, it is necessary to carry out another full charge cycle and then you can start normal operation.

To prolong the life of the battery, it is advisable to keep it charged at all times, using the power connection whenever possible. In some forums, you can still find statements that the laptop battery requires one hundred percent battery discharge. Actually this information relevant only for old batteries built on a nickel-cadmium electrochemical system. Now such batteries are not found in modern laptops.

By the way, the tips for first charging the battery above apply not only to a laptop, but also to any other device that runs on lithium-ion batteries - a phone, tablet, and so on.

The longevity of your laptop battery depends on how you treat it. More precisely - what are your rules for its storage and use.

We will tell you not only how to properly charge a laptop, but also how to properly store the battery and work properly on a laptop.

How to charge a laptop battery

At the beginning, when you first purchased a laptop, the battery charge will be negligible, so you can freely charge it to the maximum. Just do not allow the battery to completely discharge, because it can be discharged to such a point that it will not be possible to charge it at all. So how do you charge a laptop?

1. It cannot be allowed to accumulator battery completely discharged.
2. The battery must be stored charged at a temperature between +15°C and +35°C at normal, normal air humidity.
3. If the battery is stored separately from the laptop, it will discharge itself.
4. If the battery is left discharged for 2 weeks or more, then the reverse process occurs in all elements of the battery and the battery itself fails.
5. How to charge a laptop battery? You need to charge in laptops or in special ones for this chargers. Do not disassemble the battery or charge its elements yourself. If necessary, you need to contact special service centers.
6. How much to charge a laptop? You need to charge the battery for a maximum of 24 hours (unless otherwise specified in the documents).
7. The current battery status can be viewed on the battery status indicator, it exists in almost every laptop (just check where it is and how it works when buying a laptop). If suddenly, when you turn on the laptop in the electric / network, the indicator shows a malfunction for 5 minutes, then the battery is faulty. You need to turn off the laptop as soon as possible and remove the battery.
8. If the battery does not charge within 24 hours, it is defective. In this case, the battery must be immediately removed from the laptop.
9. If the batteries are defective, they should be kept separate from laptops. Beware: Defective batteries can release very harmful substances.
10. The sooner you hand over a defective battery for repair, the faster and at the lowest cost it will be restored.
11. To reduce the power consumption of a laptop, you need to change some settings. First, you need to pay attention to the display, because it is he who takes the most energy. When you reduce the brightness, then the operating time will increase.
12. Be careful if you are running a laptop on battery power:
    • when the battery charging is completed, the laptop indicates this (you can hear a characteristic sound, a message will appear on your screen that warns about the completion of charging, a special light blinks), then urgently connect the laptop to the mains.
    • if you leave the laptop turned on for a while without work, then it may fall into “hibernation”, which is characterized by low power consumption (the screen will turn off, the HDD). It can accidentally make mistakes and consider the laptop turned off, leaving it in this state. Then the battery will be discharged and will soon fail. So, when you finish work, make sure that you really turn off the laptop. But the most reliable way to store the battery so that it does not run out (when the laptop is not connected to the mains) is to simply remove it from the laptop and store it separately.
