Almost every modern laptop comes with a lithium-ion battery. Thanks to it, a long operation of the device is ensured during a charging cycle, which is very important for portable equipment. However, the battery may sooner or later lose its capacity, and its charge level will drop much faster than before. This is especially influenced by powerful loads on its internal elements, including the hard drive. But battery calibration can fix controller errors. Proper use of your notebook will help reduce the degradation in battery life.
What is laptop battery calibration for?
Calibrating a laptop battery is the most important step for a user in setting up new hardware. This procedure must be carried out both after purchasing the laptop and during its use. Calibration includes certain step-by-step actions, and it is worth doing it for the controller chip to work without any problems.
Note that physical damage or wear and tear on the device cannot be removed by calibration. This procedure only deals with problems in the laptop operating system itself.
It often happens that old devices have glitches in the form of improper operation of the controller. So the system will display an energy charge of 30%, when in fact it is 60%. The laptop will go into sleep mode when the system notices that the battery has dropped to 10%. In fact, the actual battery capacity will be 40%, which could allow the user to work with the device for about an hour.
It is to eliminate such a problem that the battery must be calibrated. This operation also eliminates the "memory effect" when the charge level is remembered when the laptop is connected to the network and will not discharge below this value, since it takes this level as a full charge of the battery.
Battery Calibration on Windows
Calibration can be performed using various methods, which include manual calibration using standard Windows OS tools. This method will work on any version of the given operating system. All that is required from the user is strict adherence to instructions and attentiveness.
First you need to check the battery capacity and charge level. The necessary information can be found using a small algorithm:
- Connect the device to the power supply and wait until it is fully charged.
- Disconnect the computer from the power supply.
- Check the charging level in the power settings.
If the user has disconnected the device from the power grid, and the charge level is below 100%, then the battery needs to be urgently calibrated.
Thanks to the Windows toolkit, you can get more detailed information about the state of the battery. To do this, you need to open the command line by entering the search command "CMD" and run as administrator by right-clicking.
After that, you need to write the value powercfg.exe -energy -output d: \ report.html, and wait for the operation to complete (the window will close).
After that, you can go to the directory specified by the program and open the sample created in html. You can study it by opening any browser. You need to scroll to the "Battery Information" tab and compare the calculated capacity and the last charge. If it turns out that the capacity turned out to be significantly more than the percentage of charging, then an urgent need to calibrate the battery.
With the help of Windows tools, you can only get data about the battery, but you need to carry out the procedure either manually or using a special program. However, first you should try to carry out the operation yourself, and if there is no result, turn to the software for help.
Manual laptop battery calibration
Manual battery calibration is carried out in a few simple steps:
- Fully charge the battery.
- Unplug and discharge the device completely.
- Connect the power supply.
In this case, it is necessary to correctly select the power supply mode, because by default each device is set to "Balanced". However, when manually calibrating, it is worth changing to "High performance" in the settings, as this will disable various energy-saving technologies and the likelihood of a successful operation will increase. In addition, with a low percentage of charging, the laptop will simply go into sleep mode, not allowing the battery to be brought to zero.
By switching the mode, you can continue to work until the device turns off by itself. After that, you need to immediately connect it to the power block and charge it to the maximum. A definite advantage of this method is the ability to work at a computer. After the battery has been calibrated, be sure to return all power settings.
Laptop battery calibration software
Such programs can play a very significant role in helping efficiency cope with battery calibration. In this case, the entire operation is carried out offline, and the user will not be required to make changes to any configuration. But it should be borne in mind that each laptop model requires its own specific program.
For ASUS notebooks, the calibration is carried out in the BIOS, since this manufacturer most often places the desired application as a technological tool of the motherboard. The same feature is available in Phoenix BIOS. You can check this yourself, and for this you need:
- Power off the laptop.
- Reboot the device and then press F2.
- Go to the BOOT tab and find the Smart Battery Calibration menu, after which you can start the process.
For Samsung and Acer laptops, there is a program such as BatteryMark. It is special in that it is able to quickly reproduce discharge-charge cycles. Its main task is to test and diagnose the battery, both in simple mode and under heavy loads. It allows you to carry out several processes in one hour.
There is also a program for Lenovo laptops called Energy Managment. It includes many functions related to battery calibration, giving the user extensive information about the state of the battery. To carry out the operation, you need to connect the device's power supply, close all running processes and applications, and you also cannot use a laptop while calibration is in progress.
HP Support Assistant software has been prepared for Hewlett-Packard notebook computers for successful operation. With an extensive selection of tools, it is possible not only to calibrate the battery, but to diagnose the entire condition of the device. To do this, go to "My Computer" and find the battery check point. After testing, the program will report on actions to improve the laptop's performance.
If the calibration was carried out in accordance with all the rules, and the state of the battery has not changed, then it has exhausted its resource. Lithium-ion batteries are designed for a certain number of cycles, after which the battery capacity is reduced. In order to return the computer to its previous work, you need to replace the battery.
What do I need to do to keep my laptop running for a long time?
Every experienced user knows that using the battery while connecting the device to the mains can damage the charging capacity. It is best to remove the battery and reconnect it during battery life. Due to the fact that each battery has its own specific number of cycles, energy consumption is wasted during natural use.
It is best not to strain the battery by draining or overcharging. It is best to let your laptop only fully discharge when you calibrate the battery. Make sure that the laptop does not overheat, do not use the device in places with high humidity.
With proper use of the laptop, you can use the device for more than 5 years. Calibrate every few months and the device will delight you with its efficient performance.
Sooner or later, every laptop owner suddenly finds out that the battery of his pet is almost the most expensive component.
This usually happens when the warranty expires. Don't be alarmed, joke.
Usually original, high-quality rechargeable batteries last longer, but anything can happen.
As a result of repeated charging and discharging cycles, power supplies wear out and their capacity decreases.
When working with a laptop disconnected from the power supply, you suddenly begin to notice that the battery life has decreased. Moreover, the indicator shows another 15% charge, and the laptop turns off without warning.
When working with large documents, such surprises are associated with the risk of data loss.
The reason for such situations lies in the incorrect operation of the controller, which monitors the battery charge level.
To eliminate this misunderstanding, it is necessary to periodically calibrate the laptop battery.
Battery Calibration
This is a simple procedure that can be performed using a special utility or manually.
The essence of the calibration is to completely discharge the battery from 100% to 0% and then charge it to 100%.
Carrying out a full cycle forces the controller to re-evaluate the condition of the battery, and the level of its discharge will be displayed correctly.
Only Lenovo and HP brand owners can use the dedicated calibration utility.
You can download it from the official website.
There is also an instruction for working with this program. Manufacturers strongly recommend using the utility, but do not deny the effectiveness of manual calibration.
It should be noted that modern laptops are equipped mainly with batteries consisting of lithium-ion cells.
Ultra-thin models and tablets are equipped with lithium-polymer batteries.
When purchasing a new battery from a store, you should give preference to original products, although cheaper third-party products are also worth considering.
In older models, you can find batteries recruited from nickel-cadmium or nickel-metal hydride cells.
So, they have a "memory effect", which is partially eliminated by periodic calibration.
Calibrating the Battery Manually
Calibration can be performed both while working with a laptop and in idle mode.
Suppose you are overwhelmed with work and choose the first option.
In order for the procedure to proceed correctly, it is necessary to clarify the power supply settings on your device and make changes to them, if necessary.
If you have Windows XP, go to Start> Control Panel> Power Options.
In the window that opens, select the "Always on" power management scheme.
In the boxes below, select "Never" everywhere and click "Apply".
If the laptop is running Windows 7, we go the same way, but in the window that opens, create a new power plan "Battery Calibration", or adjust the existing additional plan "High Performance" by selecting "Never" in all windows.
This is done so that instead of completely discharging the battery, the laptop does not go into standby or hibernation.
If you are working, then sometimes look at the charge level in order to have time to save the data and correctly shut down the programs.
After the battery is discharged, the laptop will turn off.
As soon as this has happened, we connect the power supply to the network. The battery will start charging. You can turn on the laptop and continue working.
After reaching the 100% charge level, it is advisable not to disconnect the power supply for another two hours. This completes the battery calibration.
Suppose that there is no work, and you do not feel like reconfiguring the power supply.
In this case, after making sure that the battery is 100% charged, turn off the computer.
Then we turn on the computer and go to the BIOS. To do this, immediately upon switching on, you must press the Del key. Perhaps, in your case, you will need to press the F2 key, F10 less often Esc.
As soon as the screen turns off, plug in the power supply.
The laptop can be turned on and used at will, or you can simply leave it off overnight.
The battery will charge in both cases. Calibration is not the only way to extend battery life.
How to extend battery life
If you are told that the battery will not work for more than two years, do not believe it.
To make your battery longevity, try to follow simple rules:
- It is necessary to operate the notebook in a temperature range of + 10 ° C to + 35 ° C, as the battery feels relatively comfortable at these temperatures. If the room is very hot, use a special stand to cool the bottom of the laptop.
- If you do not plan to work with the laptop for a long time, then calibrate the battery, discharge it to 80% and put it in a cool place.
- It is advisable to purchase a spare battery only when you plan to work for a relatively long period without the possibility of charging.
Buying just in reserve is strongly discouraged.
The Asus laptop is your "workhorse", has served you faithfully, but have you recently noticed that it runs out of battery much faster? And at the same time, the charge indicator shows that the battery is still ready to work. Do not rush to panic and search urgently. Try to calibrate the battery first. How to do it correctly, you will learn from the article.
Why is Asus Battery Calibration needed?
Before you get down to business, you need to tell what calibration is. This is the process by which the correct parameters are set for the battery and laptop controllers. As a result, the charge indicator displays reliable information, and the battery serves as expected. The laptop stops turning off when it pleases. Calibration allows the battery to charge the battery up to 100% and therefore take longer to discharge.
The battery life of the laptop after this procedure increases markedly.
Most often, laptop batteries require calibration:, and (from)
Asus battery calibration step-by-step guide
In a nutshell, the Asus battery calibration process consists of three steps:
- Battery charging up to 100%.
- Complete discharge to zero.
- Recharge 100 percent.
Each stage has its own nuances that you need to know in order for the result to meet your expectations. Let's talk about everything in order.
Full battery charge.
- it is necessary to prepare the computer for calibration: disable the transition to sleep mode (hibernation). Follow these steps one at a time: From the Start menu, select Control Panel, then Hardware and Sound. In the "Power supply" tab, put the icon next to "Never". Great, now the device will not "go to sleep" ahead of time;
- connect the laptop to the mains and wait until it is fully charged. In this case, working on the device as usual, or leaving it alone - this will shorten the charging time.
Discharging the battery.
- when the indicator showed that the Asus battery is 100% charged, disconnect the laptop from the power supply;
- now wait until the device is discharged to 0. The battery can be "helped" by using the laptop to its fullest: watch videos, listen to music, play your favorite games, run other energy-intensive programs;
- watch the charging indicator - the lithium-ion battery must not be completely discharged. Complete discharge is easy to check: the screen went out and the laptop does not start even when you press the power button.
Battery charging up to 100%.
- as soon as the laptop is completely discharged - immediately connect it to the mains. Leave the computer alone or work as usual - it's up to you, there is no consensus among experts.
- After fully charged, disconnect the device from the power supply. Calibration is complete, now the Asus laptop battery should work correctly, the indicator will reflect reliable information.
In addition to manual calibration, there are special utilities that will carry out the entire process on their own. You can start this operation through the BIOS, or by downloading a special utility.
A few words about the right attitude towards the Asus battery
You can extend the life of an Asus lithium-ion battery by knowing and following a few simple rules:
- Watch the temperature: it is impossible for the laptop to be turned on in a frost of -100 or in a heat from 350C. Extreme cold has a detrimental effect on a charged battery, it can be instantly discharged or even damaged. High temperatures increase the risk of damage and even explosion of the battery during operation.
- Do not leave the battery completely discharged for an extended period. An "empty" battery takes 10-14 days to deteriorate completely.
- If you constantly work from the mains, it is better to disconnect the battery so that it does not wear out.
- Calibrate your laptop every 2-3 months to keep the battery working properly.
Guide to Proper Use of Laptop Battery
Is it good to keep the battery in the laptop when it is powered from the mains? How do I calibrate the battery (full discharge)? How to store a laptop battery if it is not used for a while?
Many users ask themselves these questions, so I tried to make a kind of "mini-guide of good tips" on how to properly use the laptop battery.
When do you need to fully charge / discharge the battery?
Is it good to keep the battery in the laptop if it is constantly powered from the mains?
There is nothing wrong with that - having a fully charged battery and laptop in an outlet. Because immediately after a full charge, the battery is automatically disconnected from charging, and the laptop only works on electrical power from the mains. But it is still not good to keep the battery in a laptop if it gets very hot.
- Under normal conditions of use, when the processor and hard disk of the laptop are between 40 and 50 degrees, the battery can be left in the laptop.
- With intensive use, when the laptop gets very hot (over 60 degrees), the battery must be removed to protect it from overheating.
Battery discharge
Avoid completely discharging the battery (when the laptop turns itself off), because this overloads it and can be harmful. It is recommended to do partial discharges (up to 20-30 percent) and charges instead of full ones. In other words, we can use the laptop on batteries when we need it, and then connect to the network immediately if possible, without worrying about the battery. I personally use a laptop that is constantly connected to the network, but periodically (once every two to three weeks I specifically switch to using the battery for another discharge / charge cycle), but I never completely discharge the battery. In almost 2 years, my battery has deteriorated by only 30% compared to its original state.
Any laptop battery has a sensor that indicates the degree of load. Over time, this sensor degrades its accuracy. Inaccurate readings can lead to unwanted accidents. For example, a laptop shows that the battery power remains at 15%, when in fact there is much less. This can lead to data loss, as the laptop turns off immediately, without time to save open documents. Some laptops have a sensor calibration mechanism in the BIOS, which is responsible for discharging and fully charging the battery. So to calibrate the sensor, for every 30 normal battery discharge cycles, you need to do one full discharge and charge.
Charge / Discharge Cycles
Discharge (or charge) cycles are 100% battery life, but not all at once. For example, you can use the laptop for a few minutes a day until the battery is discharged to 50%, and then charge it fully. If you repeat the discharge the next day (up to 50%), then the cycle will be considered complete (50% + 50%), but not repetitive.
How do I calibrate the battery (full discharge)?
The best way is to use the laptop battery continuously from 100% to 3% of the charged battery. For this:
- Fully charge the battery (100%) using a mains connection during which you can use the laptop normally.
- The battery must remain fully charged for at least two hours, during which time you can use the laptop connected to the mains.
- Then go to "Power Options" in the "Control Panel" and change the settings so that the laptop goes into sleep mode when the charge remains at 3%.
- Disconnect the laptop from the power supply, and leave it on until it goes into sleep mode by itself. At this time, it can be used normally.
- After which he went into sleep mode, leave him like that for 5 hours.
- After that, we connect the laptop to the network and fully charge the battery. At this time, it can be used normally.
How to store a laptop battery if it is not used for a while?
If you do not want to use the battery for a long time, it is recommended to discharge it to 40% and store it in a cool dry place. The most ideal temperature for this is from 0 to 10 degrees Celsius. Can also be stored in the refrigerator if the battery is protected from moisture.
It is important to know that the battery life can usually not exceed 2 years from the date of production.
If you are a fan of ASUS notebooks, then you have probably heard the legend about the origin of this brand. The name of the trademark was given by the ancient mythical winged creature Pegasus, sharing the last four letters with the inventors. Apparently, initially the creatives decided to convey to users the idea of a truly unique performance of this device through a mythical image.
The flight of thought was corrected by marketers who were looking for a way to distinguish their brand, make it recognizable and one that would catch the eye in the first place. Of course, the letter A in any alphabet is guaranteed to be higher than the letter P, so the proposal to remove the first three letters was accepted.
What is calibration?
What is calibration and how does it help you? Calibration is the process of zeroing the battery voltmeter reading. Zeroing allows the controller to return to normal if the battery is, in principle, still alive. The bottom line is as follows. A 100% charge rate means that the voltage in the battery cells has reached its maximum value. This is 4.2 V. It is at this point that the controller - the electronic brain of the battery - signals that the battery is fully charged. However, if the readings are not taken quite correctly, then the signal will arrive much earlier than the battery is charged.
The controller, like any brain, sometimes needs a reboot and rethinking of the usual algorithm of actions. Simply because over many months of work, this brain begins to lose count and incorrectly count volts and percentages. If it is fully charged, then completely discharged, and then recharged to capacity, then this may well help the controller restore its functions and no longer let you down with unreliable information about the full charge of the battery. Again, let's say it again if the battery itself is normal. Myths and legends that calibration will help revive a dead battery are not relevant here.
How do I restore the battery?
Calibration didn't help and your laptop battery still doesn't hold up? This means that you will have to disassemble and restore! Consultants from specialized companies such as uabattery.com warn that laptop battery repairs should be trusted by professionals. And it's better, in general, to immediately buy a new one. In any case, it will last longer than the restored one.
Intending to deal with the naughty technique yourself? Well, then prepare a scalpel, a soldering iron, a multimeter and car bulbs. Divide the battery in half along the seam, measure the voltage across each cell inside the case, and discard those cells with less than 3.7 volts. In their place, install new elements - "barrels" (it is this household inventory that the battery cells look like). The marking of new elements should be similar to the old ones. After that, glue the body.
Is the laptop running, is the battery charging and has started to hold the charge longer than before? Congratulations! No? Then the offer of the online store uabattery.com is still valid. Contact and consultants will help you choose a new battery compatible with your laptop!
