Most of the students and people who work in the office now have a laptop, but the power of the notebook used yesterday is still good, and suddenly it can't be used today. At this time, it is more panic. If the computer's power adapter is really broken, then the notebook's battery capacity will be enough for several hours. But the quality of the power adapter is still ok, so it's time to find the part of the problem.
The notebook's power supply is divided into two parts, one is the power adapter and the other is the power cord. Now you need to step out and find out where the problem is.
Find the problem with the power cord first. If there is another power cord, try using another power cord. If the indicator on the power adapter is on, the problem is on the power cord. If you don't have it, you need to take the power adapter and power cord to try a number of different outlets. When there is a test, the indicator light is on, then the problem is found, that is, on the power line. .
If the indicator of the power adapter has been running out of the results of the previous test, it is very likely that the power adapter is faulty.
Now that the problem has been found, then how is it solved? If it is a problem with the power cord, it can be said that the plug on the power cord has been used for a long time, and the contact is not good. At this time, you can bend the right amount of the three feet on the plug on the power cord, but the best solution is to go to the store and buy another power cord of the same model.
If it is a problem with the power adapter, you can find a repair shop to repair it. If it is within the warranty period, you can return to the factory warranty. If there is no repair value, then go online and buy a power adapter of the same model.
