What stopped charging battery on laptop

The main advantage of laptops before the desktop PCs is their high mobility and Autonomous operation. Allow her to provide intensive and efficient power sources, from the parameters which depends on the duration of the laptop.

Rechargeable portable PC contains also special controllers. Very often you can face a situation when it is serviceable device, it suddenly starts to behave strangely – it will charge rapidly drops even with fairly moderate use, or the battery on the laptop is not charging fully.

Most such situations can be caused by incorrect charging or failure of the components of the electrical circuit of the laptop.

Maybe the problem is not the battery

Difficulties with the supply is not always rooted in the self-contained power source. It is possible to define at the stage of inclusion. In that case, if the device suddenly stopped showing signs of life when switched on, it is necessary to pay attention to the integrity of the electric circuit portable charging and power socket to which it is connected.

To test the charger, you can use the same from another PC laptop. If you connect the laptop also will not submit signs of life, so failure in itself or in the auxiliary power supply.

Common problems of the battery

As you know, over time, the characteristics of chemical current sources, are falling, and this process is irreversible. One of the important parameters – the number of recharge cycles, in a modern laptop is about 700 times. This means that if a portable PC connected to the mains every day, to function properly it will be at least about two years.

If a portable PC was used for a long time, it is likely that his batteries were able gradually to break down and can no longer provide enough charge.

To help determine whether it may dedicated software. Most manufacturers of equipment, such as portable PCs and laptops, released a special utility for testing the condition of power sources.

They usually give the detailed information, among which are the following parameters:

  • the working capacity;
  • voltage;
  • temperature;
  • the battery level and others.

In addition to changes in the characteristics of chemical elements, the problem may lie also in the failure of the controller. It is usually located on a special circuit Board inside the battery pack or less built into the motherboard of the laptop. Check its help specialized utility software from the manufacturer or third-party developers.

Connected but no charging

The most common problem with the autonomy of the laptop is that it is connected to the network, properly functioning, but the battery does not occur. This suggests that the electric circuit of the laptop and the charger is OK, at least in terms of electricity supply on the PC, but there is a problem with the controller. Reasons why the battery connected but not charging, there may be several.

In the battery unit of the laptop is usually a few elements from 3 to 12 pieces. If one of them was defective or prematurely failed, it disrupted the entire electrical circuit and need to replace it. When a sufficient level of knowledge of this procedure can be done independently, correctly picking necessary elements in the parameters.

Do not neglect the necessity of regular inspections of the physical condition of the contacts. Over time they can oxidize or become clogged, leading to poor contact surfaces and problems.

In this case, stationery eraser to wipe all contacts Do this procedure carefully, to avoid damage to the contacts themselves and the elements placed in the neighborhood.

Charged, but not completely

The situation when the battery is charged not completely, this may indicate such problems:

  • physical deterioration of the chemical elements;
  • the failure of the controller;
  • actions of third-party utilities and managers.

In the first case, you can use the aforementioned software methods for determining and diagnosis of all important parameters. According to the obtained results it is possible to determine their condition and need replacement.

Incorrect operation of the controller can also be defined with the help of special programs or regular methods some operating systems.

In the latter case the problem may lie in the fact that in the background is running special utilities that control power supply to the laptop and charging. Что делать, перестала заряжаться батарея на ноутбуке

As practice shows, sometimes the equipment manufacturers or third-party developers offer software that is designed to adjust the parameters of the power supply of the mobile PC. These utilities automatically change charge process as well as optimize the consumption and hardware utilization.

Disabling third-party utilities to manage the resources of PC, you can achieve the correct display of battery status and charging it to 100 percent.

If not, you must follow the steps below:

  1. turn off the power;
  2. disconnect the charger and remove the battery, if available;
  3. hold down the power button for up to 30 seconds;
  4. insert the battery without connecting the charger;
  5. to turn on the PC and check power supply.

Similarly, you can repeat this set of steps, but to turn on PC without auxiliary batteries with network connectivity. As a result of the action will disappear residual voltage, without exception, all of the capacitors on the Board.

Installed software, or other power supply it is recommended to translate into the optimal mode of supply. Using the economy or maximum performance, you should disable.

The battery of the laptop is not charging

If by results of check of the chain revealed that the difficulty lies in the self-contained power source, then the solutions to this problem may be several.

The main ones:

  • replacement of one or several chemical elements in the block;
  • calibration of the controller;

  • checking and cleaning of contacts.

Of the failed individual chemical current sources in the block can break an electrical circuit, making impossible the charge. Their replacement can be carried out independently or in the service center.

The failure of the controller can be caused by failure or incorrect operation. In the first case, you will need to replace it or to repair the entire battery.

To diagnose the problem will help third-party tools, the most popular of which are:

  • Aida64;
