Disruption of laptop battery charging is one of the most common malfunctions. This problem occurs most often after three years of device operation. There may be several reasons in this case - from the breakdown of the laptop itself to damage to the contacts in the power supply.
How to determine the cause
Experts point out that most problems with laptops arise from improper use. For example, some owners of such devices almost never turn them off using a simple method of closing the lid. In this position, the system goes into sleep mode, but the laptop continues to work. Doing so can be the main cause of battery indicator malfunction.
The first step is to identify the source of the problem. If the laptop does not turn on, the screen does not function and no visible processes occur, then most likely the culprit in this case is a faulty battery. In the event that the laptop turns on, functions normally with the charger on, but turns off without it, then the power supply is the cause of the malfunction.
If, when examining the laptop, you notice any damage - cracks on the cord, foreign objects in the slots for connectors or problems with the device case, then it is better to send the computer to the center for diagnostics right away.
Examine the laptop carefully. All connectors must be correctly and firmly inserted into their respective slots. The cause of the malfunction may be not only in the laptop itself, but also in the power outlet. That is why try moving your laptop to a different room and turning it on from a new power source.
The laptop battery may not charge due to a malfunction of the charger itself. The easiest way to identify this problem is to replace the power supply. If the laptop works normally with another device, then just purchase another charger.
A more serious problem is the breakdown of the laptop itself. Without special knowledge and skills, you will not be able to repair it. It is better to take the device for inspection to a service center or use any salon where such services are provided.
What to do
There are a few things you can try to troubleshoot a laptop battery that is faulty. Discharge the device completely first. This method is relevant only if the battery has stopped charging at 100% and the laptop is still working. After such manipulation, turn on the power supply and wait until the charging process is completed. Once the battery indicator has reached the correct level, then you have nothing to worry about.
Some manufacturers place certain restrictions on the performance of the battery charging indicators. In this case, not only 100% can be considered the norm.
Please note that most malfunctions can only be detected on the basis of special diagnostic data. If the power supply is operating normally, the cause of a malfunctioning battery charge may be internal damage to the connector, breakdown of the printed circuit board, or burning of its tracks.
