If the tablet, laptop or phone is connected, does not charge, what should I do?

The irrepressible technological race of computer manufacturers today is aimed primarily at achieving a super-powerful result in the miniature form of the final product. As a result, compact notebooks are getting thinner, lighter and more powerful every year. In some cases, mobile phones have outperformed office PCs in their functionality. It seems like a delirious desire to "keep the whole world in the palm of your hand" today is a partially realizable 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 "device connected, not charging" is quite "popular" in the scale of its manifestation. However, in most cases, this kind of malfunction can easily be solved by yourself. This is exactly what will be discussed in this article-guide.

Harbinger of trouble: the consequences of ignorance

It's clear, the mobile device, deprived of the ability to work autonomously, loses all the advantages of its purpose. The banal ignoring of operational rules will sooner or later negatively affect the performance of "mercilessly" used electronic equipment. The ironic conclusion in the form of a joke: "If your laptop, even after being connected to an electrical outlet, does not charge ... do not rush to throw out 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, improperly generates energy services for his electronic "friend".

The fact is that in most cases, only due to the user's fault, there are breakdowns related to the violation of the power supply scheme of mobile devices, often expressed by a question word: "charging is connected, but not charging." That for you it was not an unexpected surprise (excluding manifestations of factory rejection) an unexpected failure of the battery to be charged, it is necessary to systematically conduct preventive maintenance of your device. A cell phone, a tablet or a laptop are all electronic devices that can autonomously operate from the battery. Therefore, the principle of "power supply" for all of them is almost identical. At the same time, there are a number of distinguishing features in the operation of each individual device, on the "board" of which there is a "life-supporting" battery. In general, the problem covered requires a serious approach and a variety of solutions.

Connected, not charging: the main reasons and recommendations for repair

So, let's take a closer look at typical battery failures. Consider a number of common mistakes that allow owners of portable computing equipment, tablets and mobile phones in the process of operation. Also, we touch on some issues of diagnostics and prevention of power system failure of the above-mentioned devices.

Reason number 1. Uncalibrated battery

First of all, it is worthwhile to know that the modern battery (hereinafter referred to as the lithium-ion battery type) is devoid of the "memory effect". That is, at any time the user can energize the battery without waiting for the recommended charging value of 15-20% of the total power rating. However, the problem of "plugged in, not charging" can be the wrong 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 allow to optimize the operation of the power supply elements, and at the same time the system will receive up-to-date information on the battery condition. It is possible that a few full charge / discharge cycles will fix the situation: connected - not charging.

Reason number 2. Temperature conditions

The cold environment adversely affects battery performance, as the chemical process inside the battery tanks is significantly slowed down. Moreover, the accumulator begins to lose the accumulated electric potential. As a result, the battery is banally discharged, and with a long exposure to low temperatures it can completely lose its starting momentum. In such cases, the unlucky user will have to ask the question: "Why is it connected, but not charging?". However, it is correctable - use the universal charging "frog", having previously found on the clamps AKB marking "+/-".

Hot weather also adversely affects the full performance of the battery. Since the capacity of the battery, as in the above-described case, quickly lose its electric power potential. Hot air environment, in the "tandem" with the heat release of the internal components of the mobile device system is highly likely to contribute to the emergence of a critical overheating moment. That in the end can completely bring "toasty" electronics out of order. Therefore, so that you do not have any difficulties, such as "Charging is connected, but not charging," remember the favorable temperature regime.

Reason number 3. Water and its derivatives

Pay attention to battery clamps, maybe they are oxidized. In the event that such a "corrosion trouble" occurred with a tablet or a mobile phone, the design feature of which is a non-removable battery, the chances of a successful resolution by own forces can be negligible. Since the process of disassembly often requires not only specialized knowledge, but also considerable experience in this field. It is difficult for these devices (in terms of resolution) the situation: "connected, not charging", in the case of the laptop is fairly simple to perform.

It is enough to unfasten the battery, and access to the clamps is 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 for disassembling the tablet, mobile phone) - remove the battery from the device. Clean the contact pads (connecting stub) with an old toothbrush, soaked in the same alcohol solution. Gently reverse the assembly order.

Reason number 4. The battery is not connected properly

It does not charge what to do and how it is - difficulties that can actually be a manifestation of elementary carelessness of the user when the battery is positioned in the corresponding connector. Not fully compressed battery will be incorrectly perceived by the laptop system. Which will become a kind of obstacle for subsequent charging processes.

Considering this problem on the example of a mobile phone, it is worth noting one important detail ... Often, cellular devices do not perceive third-party batteries or do not fully work with such power supplies. In the case of such an unpleasant situation for many users, which requires an early resolution of the problem "writes connected, does not charge," replace the battery with the original product.

Reason number 5. Mechanical damage of connecting elements

In the process of using the charger, the charger cord often bends, which in the end can lead to a violation of the supply of electrical energy through the circuit. In this case, there is a risk of a short circuit. At the same time, the power supply connector and the system connector of the "battery" device are most susceptible to the destructive effect of the mechanical type (a systematically produced process of insertion and removal of the power plug).

When a user encounters a typical "laptop is connected but not charging" problem, you should carefully inspect the power supply connector. The deformed sections of the wire are the basis for replacing the memory or for servicing the device.

Reason number 6. Software failure

The vast majority of autonomously operating electronics are equipped with special graphic sensors that reflect current information about the power source used. Integrated in the OS power management service through changing settings will optimize the battery. However, a common complication, usually implying a memory malfunction and consisting in a capacious phrase "the laptop is connected but not charging," often occurs due to a "flown" driver. Since it is the specially programmed 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 reinstallation, 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 in the operation of the battery, as well as facilitates the correct calibration of battery capacities. By the way, in the laptops of the American brand Hewlett Packard this is the most popular method of restoring the battery capacity, if the battery is connected, HP is not charging.

Multifunction telephones and tablets also have an energy monitoring service. However, it is not uncommon for the system software of the device to be completely replaced to resolve the problem. The rather complicated process of flashing the software part of a mobile phone involves the intervention of a qualified specialist, since the above situation with the laptop is "connected, it does not charge HP" in the case of a cellular device is radically different in terms of implementing recovery operations.

A Few Words About Hard Reset Function

If there are "electrical misunderstandings", you can resort to a universal method - to perform a complete reset of the data of the computing device ("hard reset" also applies to mobile phones and tablets). So to say, to bring the device into its original state, turning the system back to the factory settings. It should be noted that in the mentioned devices this function is used differently. However, the result is usually always positive. And do not forget to save the data from the system partition. Since they (during the reset) will be lost.

The inevitable ending, or A few words for the edification

Within the framework of the article presented, you were introduced to the main reasons for the often occurring malfunction "the laptop is connected, but not charging." As you could see, such an embarrassment, which caused mixed problems with the "filling" of electricity in a mobile phone battery, as well as a tablet, has many scenarios of its manifestation.
