The irrepressible technological race of computer manufacturers today is aimed primarily at achieving an ultra-powerful result in a miniature form of the final product. As a result, compact laptops become thinner, lighter and more powerful every year. Mobile phones in some cases have become superior in functionality to office PCs. The seemingly delusional desire to “hold the whole world in the palms of hands” today is partly a really feasible task. Nevertheless, along with the incredible successes of engineers in the field of minimization, there are a lot of "energy" flaws. So, the problematic situation “the device is connected, does not charge” is quite “popular” in the scale of its manifestation. However, in most cases, such malfunctions can easily be resolved on their own. This is what will be discussed in this article-guide.
Harbingers of Misfortune: The Consequences of Ignorance
Of course, a mobile device, deprived of the ability to work autonomously, loses all the advantages of its purpose. The banal ignoring of operating rules will sooner or later negatively affect the operability of the "mercilessly" used electronic equipment. An ironic conclusion in the form of a joke: “If your laptop does not charge even after it is connected to the power supply ... do not rush to throw away a high-tech device. After all, it can be used as a stationary PC ", it makes no sense. This is exactly what can happen if the user unknowingly or for another reason, for what reason does the energy service of his electronic "friend" incorrectly.
The fact is that in most cases, solely due to the user's fault, breakdowns occur due to violation of the power supply circuit of mobile devices, often expressed by the interrogative phrase: “charging is connected, but it does not charge”. In order for you not to have an unexpected surprise (excluding factory defects) an unexpected battery failure to charge, you must systematically carry out preventive maintenance of your device. A cell phone, tablet or laptop are all electronic devices that can work independently from a battery. Therefore, the principle of "power" for all of them is almost identical. At the same time, there are a number of distinctive features in the operation of each individual device, on the "board" of which there is a "life-supporting" battery. In general, the problem addressed requires a serious approach and comprehensive solutions.
Connected, does not charge: the main reasons and recommendations for repair
So, let's look in more detail at typical battery failures. Consider a number of common mistakes that owners of portable computing equipment, tablets and mobile phones make during operation. We also touch on some issues of diagnosis and prevention of breakdowns in the power system of the above devices.
Reason # 1. Uncalibrated battery
First of all, it is worth knowing that a modern battery (hereinafter referred to as the lithium-ion type of battery) is devoid of a “memory effect". That is, at any time, the user can energize the battery, without waiting for the recommended value for charging 15-20% of the total power rating. However, the problem of “connected, does not charge” may be due to improper operation of the battery controller, which is a kind of “energy intermediary” between the battery and the electronic device.
Therefore, if there is some technical “misunderstanding”, it is necessary to calibrate the battery, which will optimize the operation of the power elements, and at the same time, the system will receive up-to-date information on the state of the battery. It is possible that several complete charge / discharge cycles will correct the situation: connected - it does not charge.
Reason number 2. Temperature mode
A cold environment adversely affects the operation of the battery, since the chemical process inside the battery containers slows down significantly. Moreover, the battery begins to lose the accumulated electric potential. As a result, the battery discharges corny, and with prolonged exposure to low temperatures, it can completely lose its starting impulse. In such cases, the unlucky user will have to wonder: “Why is it connected, but not charging?”. However, this is fixable - use the “frog” universal charger, having previously found “+/-” marking on the battery terminals.
Hot weather also negatively affects the full performance of the battery. Since battery capacities, as in the case described above, quickly lose their electrical power potential. The hot air of the environment, in a “tandem” with the heat release of the internal components of the mobile device system, will most likely contribute to the emergence of a critical moment of overheating. Which ultimately can completely disable the “fried” electronics. Therefore, so that you do not have any difficulties, such as "charging is connected, but it does not charge," remember the favorable temperature regime.
Reason number 3. Water and its derivatives
Pay attention to the battery terminals; they may have oxidized. If such a “corrosion nuisance” occurred with a tablet or mobile phone, the design feature of which is a non-removable battery, then the chances of a successful resolution on its own can be negligible. Since the disassembly process often requires not only specialized knowledge, but also considerable experience in this field. The situation is difficult for the mentioned devices (in terms of resolution): “connected, not charging”, in the case of a laptop it is quite simple to implement.
It is enough to unfasten the battery, and access to the terminals obtained. Clean oxidized (contaminated) contacts with alcohol. Then replace the battery. If you are confident in your own abilities and your confidence is supported by certain knowledge (manual or video on disassembling a tablet, mobile phone) - remove the battery from the device. Clean the pads (connection cable) with an old toothbrush moistened with the same alcohol solution. Carefully reverse assembly.
Reason number 4. Battery not connected properly
It does not charge, what to do and how so - difficulties that can actually be a manifestation of the elementary inattention of the user at the time of positioning the battery in the corresponding connector. Not fully squeezed battery will be incorrectly perceived by the laptop system. What will become a kind of obstacle for subsequent recharging processes.
Considering this problem on the example of a mobile phone, it is worth noting one important detail ... Often, cellular devices do not accept third-party batteries or do not fully work with such power sources. In the event of a situation that is so unpleasant for many users and requires an early resolution of the problem: “it is connected, it is not charging,” replace the battery with the original product.
Reason number 5. Mechanical damage to the connecting elements
In the process of using the charger, the charger cord often bends, which may ultimately lead to a disruption in the supply of electrical energy through the circuit. In this case, there is a risk of short circuit. At the same time, the power supply connector and the system connector of the “battery” device are most susceptible to the damaging effects of the mechanical type (a systematic process of inserting and removing the power plug).
When a user encounters a typical “laptop connected but not charging” problem, you should carefully examine the power supply connector. Deformed sections of wire - this is the basis in order to replace the memory, or to carry out maintenance of the device.
Reason # 6. Software crash
The vast majority of autonomously working electronics are equipped with special graphic sensors that reflect current information about the power source used. The power management service integrated into the OS by changing settings will optimize battery performance. However, a common complication, usually implying a malfunction of the memory and consisting in the capacious phrase “the laptop is connected but does not charge,” often arises due to a “flown” driver. Since it is the specially involved program code that controls the energy-saving system of the separately presented electronics.
To restore the "energy balance", download the latest driver from the official site. After reinstalling, the problem should disappear. It is worth noting that most portable equipment has in its arsenal a special program that allows you to make some changes to the battery, and also contributes to the correct calibration of battery capacities. By the way, in laptops of the American brand Hewlett Packard, this is the most popular method for restoring battery life, if the battery is connected, it does not charge HP.
Multifunctional phones and tablet computers also have an energy monitoring service. However, there are frequent cases when, in order to solve the problem being addressed, it is necessary to completely replace the device’s system software. A rather complicated process of flashing the software part of a mobile phone involves the intervention of a qualified specialist, since the above situation with a laptop “connected, does not charge HP” in the case of a mobile device is fundamentally different in terms of the implementation of recovery actions.
A few words about the hard reset function
If you find "electrical misunderstandings", you can resort to a universal method - to perform a complete reset of the data of the computing device ("hard reset" is also applicable to mobile phones and tablets). So to speak, bring the device to its original state by rolling the system back to the factory settings. It is worth noting that in the mentioned devices this function is activated in different ways. However, the result is usually always positive. And do not forget to save data from the system partition. Since they (in the reset process) will be lost.
The inevitable finale, or a few words for edification
In the framework of this article, you got acquainted with the main causes of the often occurring malfunction "the laptop is connected, but does not charge." As you can see, such a difficulty, which caused controversial problems with the "pouring" of electricity into the battery of a mobile phone, as well as a tablet, has many scenarios of its manifestation.
