Laptop computer about electricity no electricity, is the power adapter problem?
"The adapter light is bright" is just a matter of line between the AC power supply and the power adapter, and the power adapter to the computer that line may be bad or the computer interface is not good. Practice shows that the adapter's computer interface where the line is most likely broken
To judge this is very simple:
1. The computer is in the battery state to see if it works properly. If it does not work, the battery has a problem
2. Remove the battery from the computer with a power adapter to see if it is working properly. If not, there is a problem with the power adapter
3. If the two states can work that is the computer charge management part of the poor contact and other issues.
This situation is definitely not about what power off, if it is really about electricity no electricity, then your laptop is a one-time shutdown, rather than the screen flashing.
I think this situation is more like a laptop screen lamp problem. Is unlikely to be a power problem. The screen flashes from the surface that there may be enough current. If the adapter can not provide enough current for the notebook, then the notebook will be over-current protection, which automatically shut down.
You can find an adapter with the same output voltage as your adapter, the output power is greater than or equal to your adapter other adapter, if the situation remains the same, then it is certainly the problem of the lamp.
But the inferred will not be a power problem.
