Answer:

According to the situation you describe is likely to be the problem of power adapter, and now the power adapter has an electronic chip, unlike the old adapter so simple. It is best to find professional personnel to detect what their best not to hands.
Into bios, look inside the power adapter, there is no display of its information. Such as how many watts. If there is no power adapter problem. change
It is estimated that the power is broken, for a try
Usually the power adapter is faulty, it is best to re-purchase one; There are two main indicators of the adapter, namely: voltage and current, and the voltage and current for each notebook is not the same, the configuration or purchase must pay attention; In the notebook's manual or "specification range" or "electrical parameters", generally indicate the basic parameters of the adapter, the most important of which is the voltage and current, if there is no original adapter, you need to find alternatives, we must choose: 1, the new adapter of the voltage and the original exactly the same; 2, the current should be slightly larger than the original maximum output current (20 ~ 30%); 3, the positive and negative polarity of the adapter plug must be the same as the polarity of the socket (ie, the original adapter) 4, the hole diameter of the plug must be the same as the diameter of the socket (ie, the original adapter) (the plug has a large hole and hole points).
