This video explains how to check if a laptop's power source is working correctly. First, you should check the cables and make sure they are not broken. Then, you should compare the direct current output voltage with the electric circuit diagram. If the voltage is lower, it means that the power source is damaged and needs to be repaired.

• 00:00:00 The laptop's power source is the source of energy that transforms alternating current into direct current to allow the laptop to work. It is also used to charge the laptop's battery, so it is called a battery charger to check that the power source is working correctly. To check that the power source is working, you should check to see that the cables connecting the power source to the laptop and the laptop itself are not broken or that the conductor material is exposed. Compare the direct current output voltage with the electric circuit diagram to see if it is lower or not there. This means that the power source is damaged and needs to be opened to be repaired. Laptop power sources are usually made of plastic and so you must cut the connection between the two covers with a knife and pull them apart inside the power source. You will find the power supply's circuit protection rectifier and filter in this case. To detect problems with the rectifier and filter, you must connect the power supply to the laptop's power cable and measure the voltage of direct current on the supply side. If there is no voltage
