Antipyretics for children are prescribed by a pediatrician. But there are situations of emergency care for fever, when the child needs to give the medicine immediately. Then the parents take responsibility and apply antipyretic drugs. What is allowed to give to infants? How can you bring down the temperature in older children? Which medications are the safest?
Often, due to improper charging, the laptop battery is out of order. At best, it will show the wrong percentage of charge, the battery calibration will help here. At worst, the battery will completely fail, where only its replacement will help. Therefore, to improve its performance, today's article will talk about how to do a laptop battery calibration.
Once I talked about how to properly charge the laptop battery, so read it necessarily, observing the rules listed in that article, will help to serve your battery longer.
When do I need to calibrate the battery?
Calibrate the battery should be done when your laptop starts to show the wrong percentage of charging, for example, shows a percentage of 90, and shuts down very quickly, like after 20%.
It happens because of the "memory effect" of the battery, it remembers the level of charging and it turns out as if the battery is fully charged, in fact, the charge was disconnected much earlier than its end, and the battery remembered it as a full charge. Problems with memory have always been in nickel batteries (NiMh, NiCd), but as practice shows, Li-Ion is also subjected to this, although not so much. I remember, many claimed that lithium-ion batteries are not affected by the memory effect, apparently not true. Fragment from Wikipedia:
Researchers from the Swiss Institute Paul Scherrer, along with colleagues from Toyota Research in Japan, found that the widely used type of lithium-ion batteries are still subject to a negative "memory effect".
In general, the calibration should be done about once every three months, for prevention, this is enough for the normal operation of your laptop's battery.
How to calibrate a laptop battery.
In principle, there is nothing complicated, the only thing that the process itself can be very long.
Some laptops, such as the Asus, have built-in utilities for calibrating the battery. But in this article we will talk about another method that is suitable for any device. Now consider in detail how to calibrate the battery.
Before the start of the process, you need to disable the automatic shutdown of the laptop, the transition to hibernation (hibernation), which is performed at some specific percentage of the remaining charge. Let's say this is 10%, then the battery will not be completely discharged, in our case it is necessary to completely discharge, to 0%. You can disable this by going to - Start\u003e Control Panel\u003e
Equipment and sound\u003e Power supply and set the "Never".
The next step is to fully charge the battery, up to 100%.
After that, you need to unplug the laptop from the network and discharge the battery. Quickly it can be done, for example, by playing in some, you can also increase the brightness of the screen, which will help to discharge the battery faster.
And so, the battery is low, the laptop turned off, now, immediately it is necessary to charge it completely, do not leave the battery for a long time, this can disable it. During charging, the notebook should be turned off.
Here such, uncomplicated battery calibration process laptop. You should do it if you did it. But, if your battery has not been calibrated, it may be necessary to replace it.
A few more tips for operating the battery:
Do not expose to direct sunlight. The optimum temperature for storing the battery is + 10 ° C - + 35 ° C.
Once again I repeat that it is not necessary to keep the battery completely discharged - this is a sure death to your battery. Also, do not leave it to storage outside the laptop, when its charge is 100%, the optimal percentage of charging for storing the battery is approximately 50%. So you can safely forget about him for several months.
Proper operation and timely calibration will not prevent your battery from failing before the due time. That's all about the laptop battery calibration. Good luck.
The new laptop battery works without problems. But over time, the correctness of the settings is lost, the device starts to show a charge that does not match the actual capacity of the battery. In order to establish the correct operation of the controller, the batteries are calibrated. There is a reduction of the settings of the battery cells and the controller to one level. Simply put - this reset the characteristics of the battery to the initial settings.
How to restore the battery for a laptop: a simple instruction of 3 steps
Calibrate the battery in two ways: through the software settings of the laptop or by sequential charging / discharging the battery.
The first option is for the sophisticated users, because you need to go into the BIOS settings and run a special utility or download the battery calibration program from the Internet.
Experts BatteriOn told how to calibrate the battery in a more simple and affordable way.
Self-calibration of the laptop battery:
- Fully charge the laptop. No matter how dilapidated the battery is, the main thing is that the calibration process is continuous. You can work on the computer while charging. But keep in mind that the use of energy-intensive programs and applications makes the process longer. Once the 100% value appears on the indicator (the battery is fully charged), unplug the notebook from the mains.
- The next stage is a complete discharge. Note that the "Hibernation" ("Sleep") mode must be disabled. Otherwise, the device will shut down by 7% of the charge - sooner than necessary. For proper calibration, discharge the battery completely. Advice from "experienced users": you can speed up the discharge by running video, game, Skype, Internet at the same time, putting the movie on the download. The computer should shut down.
- Again, charge the laptop to 100%. Once the screen goes out - immediately connect the laptop to the power. Do not leave the lithium-ion battery completely discharged for a long time - the device may completely break down. Leave it until it is fully charged. As in the first stage, it is allowed to use the laptop during power from the network. When the laptop is fully charged, you can consider the calibration process complete.
As you can see, nothing complicated. It is enough to follow the instructions completely.
Each laptop owner is interested in how to extend the battery life of the laptop. The answer is simple: use the battery correctly and calibrate every few months. Then the work of your laptop will be stable even away from the outlet!

If you are a fan of ASUS notebooks, you probably heard a legend about the origin of this brand. The name was given to the trademark ancient mythical winged creature Pegasus, having shared the last four letters with the inventors. Apparently, initially creatives decided to convey to the 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 highlight their brand, make it recognizable and so that would catch the eye first. Of course, the letter A in any alphabet is guaranteed above the letter P, so the proposal to remove the first three letters was accepted.
What is calibration?
What kind of calibration and how does this help you? Calibration is the process of resetting the battery voltmeter. Zeroing allows you to restore the controller back to normal, if the battery is, in principle, still alive. The essence of the following. A charging rate of 100% means that the voltage in the battery cells has reached the 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 completely correct, the signal will be received much earlier than the battery is charged.
The controller, like any brain, sometimes needs to reboot and rethink the usual algorithm of actions. Simply because for many months of work this brain starts to lose count and incorrectly count volts and percentages. If it is fully charged, then completely discharged, and then recharged to the eyeballs, then it could well help the controller to restore its functions and no longer fail you with unreliable information about the full charge of the battery. Again, we will repeat again if the battery itself is normal. Myths and legends that calibration will help revive a dead battery is not appropriate here.
How can I restore the battery?
Calibration did not help and the battery of your laptop still does not hold? So, it is necessary to disassemble and restore! Consultants of specialized companies - in particular, uabattery.com - warn that repair of batteries for laptops should be trusted by professionals. And it is better, in general, to buy a new one right away. In any case, it will last longer than the restored one.
Are you going to deal with disobedient technology yourself? Well, then, prepare a scalpel, a soldering iron, a multimeter and car bulbs. Divide the battery along the seam into two parts, measure the voltage on each element inside the enclosure, and discard the ones where the voltage is less than 3.7 volts. In their place, install new elements - "kegs" (this battery is similar to this hozinventar). The marking of new elements should be similar to the old ones. After that, seal the body.
Does the laptop work, the battery is charging and started to 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!
