Computer technology has long become an integral part of modern human life. It is used in various enterprises, in offices and for performing various tasks at home. Fast information processing, the ability to interact with other users and the emergence of network access are the main advantages of using computers.
Manufacturers are trying to improve performance, add new features and improve the quality of technical specifications. But despite the application of advanced ideas and developments, over time, any equipment can fail and not fulfill its functions in full. This can significantly slow down or completely stop the workflow, so it is important to quickly diagnose and fix problems.
In our article, we will talk about a way to check the status of the power supply using various devices. This method will allow you to check the condition of the equipment without disassembling the case and internal structure.
What are multimeters?
Such a check can only be carried out using special equipment. This device is called a multimeter. If this is your first encounter with this element, it will be useful to learn about its design, principle and features of functioning.
Multimeters are special devices that capture electric current and read information about its strength, voltage and resistance. There are various models of devices that differ in the method of application and the accuracy of the data obtained. It is also called a tester, because the test consists in testing the electrical signal passing through the wires and the main elements of the electrical circuit involved in ensuring the operation of all equipment.
Important! Typically, this method is used in the absence of external damage after diagnosis. If you encounter a problem with the functioning of the laptop, this method will help identify the source of the malfunction.
How to check laptop battery?
If a problem occurs in the power supply, you can use various methods for assessing defects. Of course, it is worthwhile to conduct an external inspection to detect mechanical damage. If this fails, you should use a tester. To use it, you must complete the following action plan:
- Connect the power supply to the network. Inspect socket integrity and wire quality.
- After that, you need to ensure the connection of the tester. Depending on the model used, the device can be run along the unit (wireless test method), when using wires, you need to connect special terminals to the equipment.
- The connection starts with the red wire, which is inserted inside the plug, after which the black wire is brought up with the tip up next to the power supply.
- After that, evaluate the readings on the main screen of the device. With a sharp deviation and a pendulum-like swing of the arrow, you can judge the equipment malfunction, in which case it is worth replacing the elements.
- If the readings on the device are not recorded, this may indicate a wrong connection of the multimeter, or damage to the wires that provide the connection of the power supply with the laptop. In this case, you will have to change the wiring, which is much cheaper compared to changing all the equipment.
Important! If you manage to detect a malfunction, you can make an independent repair or seek the help of professionals. To get free warranty assistance, you cannot repair the device yourself.
The frequency of testing depends on the intensity of operation and the operating mode of the equipment. If you notice various malfunctions in the operation of some components of the equipment, you should pay attention to the power supply. To check, you can use a different type of battery, if with it the laptop is functioning properly, it is worth changing the element.
It is also recommended to carry out diagnostics at least once a month, this will help in the early stages to identify problems and fix them to extend the life of the device.
