Power adapter plugged into the computer on the flash does not plug in the normal light plug on the computer when the power is also broken or the sockets of the power adapter plug problem
3, the power adapter is normal, the interface is normal, the computer is not normal, the computer pull the current is too large. But from what you said the situation, the computer should be normal, so look at the following two cases.
If the interface is no problem, look at the same output voltage, the current is not less than the adapter used to see if there will be such a problem, you can determine the power adapter is not a problem.
2, the power adapter is normal, the computer is normal, but the interface is not normal, such as the interface where there is a short circuit.
There are three reasons:
1, the power adapter is not normal, may be the power adapter aging or fall, resulting in a transformer inside the problem, lack of carrying capacity, such as the rated output 1.95A, but now only output 0.6A or even lower, then you connected to the computer When the output current is large, the power adapter can not stand, protected, has been restarted, there will be power adapter lights flash.
