If not, you can confirm the problem in the adapter or motherboard.
1, with a multimeter to check whether the normal socket, the supply voltage is 220V.
If the utility voltage is not normal, it is recommended to replace the use of environmental testing.
2, with a multimeter to check the power adapter output voltage and current is consistent with the label.
If the gap is very large, and the mains voltage is normal, you can determine the power adapter failure,
Need to replace the notebook power adapter.
3, if the above check is normal, remove the laptop battery, do not external adapter. Press and hold the notebook power button 5 seconds to repeat 3 times. After releasing the notebook residual charge, insert the power adapter separately, power on the test.

Notebook power adapter is standard, the ambient temperature of 40 degrees, the adapter temperature should not exceed 55 degrees, the general manufacturers of the adapter can fully meet this requirement, if you are a big brand, it should not appear this Kind of problem.
- Q:Laptop adapter and computer interface contact bad DIY repair?
