The laptop power adapter is one of the most prone to failure accessories, and the all-plastic sealed case is not easy to open, so many people are helpless when the laptop power adapter is damaged. In fact, it is not so difficult to troubleshoot the power adapter at home. Here are some practical methods on how to troubleshoot the adapter yourself.
In the case that the power adapter has a problem, first of all we need to determine whether the contact problem caused the failure of the adapter. We can first try to shake the power connector or laptop battery lightly to see if the power adapter or laptop battery is in good contact. If the contact is found to be abnormal during the inspection process, the cause of the failure is likely to be the deformation of the power connector of the computer or the decrease of the elasticity of the battery contacts. Try to reinstall the power adapter or battery.
After checking the connectors of the laptop power supply and battery, if there is no problem, then the second step we need to do is to open the package of the power adapter, and then use a multimeter to measure the output voltage of the power adapter or battery, so as to Judge and check whether the output voltage is stable, and whether the actual output voltage value is consistent with the nominal voltage of the power supply. If the output is unstable or the actual output voltage differs greatly from the nominal value of the product, the damaged power adapter or battery needs to be replaced.
If in the above detection steps, the output voltage and contact of the power adapter are normal, then the fault is probably not the adapter itself, but the notebook power board or motherboard. This requires the user to send the faulty laptop to the repair place, open the laptop case and check whether the power board is in good contact with the motherboard. If the power board and the battery are in good contact, then the replacement method can be used to check whether the power board is normal. If any abnormal situation is found, it can be replaced in time.
