According to statistics, choosing a laptop computer, the future owner is least interested in what kind of laptop battery is used in this model. Well , there’s no need to even talk about learning the rules for using this battery .
The natural result of this approach is complete disregard for the manufacturer's recommendations and accelerated battery wear. It may seem to a person who has never looked in the “Notebook Battery” section of price lists of computer companies that this component of a computer system is a consumable item and does not require any special treatment. In reality, the cost of the battery is often from half to a quarter of the price of the product, which is quite a lot. Therefore, such a valuable component as a laptop battery must be protected.
Terms of Use
One of the most common mistakes made by owners of laptop computers is the constant work with the battery. Nowadays, when full-sized personal computers are gradually giving way to their compact mobile counterparts, for many users the laptop is used as a stationary desktop system.
That is, more than 90% of the time it works from the network, and the internal source is inactive. Because of this mode, the laptop’s battery degrades very quickly, losing capacity, and when it becomes necessary to work autonomously, the system’s operating time does not at all correspond to the instructions (as a rule, it is several times smaller).
Conclusion: with prolonged use of the laptop as an alternative to a desktop computer, the internal energy source must be removed. At the same time, its charge level should be about 40-50%, and once a month you should recharge the battery by installing it back in the laptop. As an option: you can periodically switch the system to battery power.
The second mistake is that few people know that there is a calibration function. As a result, due to the unconfigured operation of the controller, for example, the battery for a Toshiba laptop (and not only) loses capacity. The calibrated controller has the ability to accurately determine the remaining charge, current state and level of fullness of the cells.
The essence of this function is that at first there is a full charge, its level is "remembered" by the controller circuit as the maximum value. This is followed by a discharge until the computer shuts down. This is fixed as the minimum threshold. If calibration is not performed periodically, the actual and recorded values may vary significantly. Because of this, the charging process can begin long before the battery is completely discharged (or the indicator will show a full battery, and the operating time will be only a couple of minutes). Conclusion: you need to go into the BIOS (for example, the F2 button) and activate the "Calibration" field. As an option: download a special utility from the website of the laptop manufacturer and use it to configure.
Some interesting facts
For long trips, when the power supply network is unavailable, and it is impossible to charge the battery in the standard way, a solar battery for the laptop comes to the rescue. Inside this device is its own battery, recharged from the energy of sunlight. Conveniently enough, but there are a number of features that can be found out by studying the relevant information.
In Toshiba laptops, for example, a function is provided that allows you to specify the mode of use - stationary or mobile. The operation of the charge controller is adjusted accordingly, extending the battery life.
