To detect a defective power supply, you must be aware of the symptoms of the defect. Noise, interference, heat and other factors indicate defects. Further explanation:
The laptop automatically turns off after the battery is turned on, cannot be charged, or the notebook is turned off after a certain working time, and can only be used again after cooling.
Cause: The laptop is powered by an unsuitable power source, such as too little power.
When the power adapter is connected to the notebook, the power indicator on the power adapter blinks or does not illuminate.
Cause: The power supply is overloaded. In addition, there may be defects in the control components on the motherboard of the notebook computer.
The control LED is not bright or very weak. The laptop is working fine on the network, but the battery is not charging.
Cause: The power supply is too weak. In many cases, it is possible to set the voltage required for a universal power supply through a switch. If necessary, you can correct the error by changing the voltage level.
The laptop can detect changes in brightness during operation even if it is connected to the mains.
Cause: If the software's power settings are set to the default settings, the brightness may change because the device will switch permanently between AC and battery power. This may be caused by a loose connection of the power outlet or the power cord itself.
A beep sounds when the power is connected to the power source.
Cause: Although the power adapter is not fully defective, it may fail at any time. A weak solder joint on the indoor capacitor triggers noise. It is recommended to purchase a new power supply because sudden defects can cause serious damage to the notebook.
