AC adapter is LI SHIN brand, the recent frequent failure, can not pass the power (light does not light).
That is, every day to plug in the power supply that moment often hear the spark sound, and sometimes power (light), and sometimes can not pass (light does not shine), what is the story, my devil? Can not be energized sometimes to put a few hours, then try again and again, it seems that the problem is intermittent attack. If you shut the machine, unplug the power, they want to plug in the power on, this is not power. Has bought another power supply, the same problem.
if the power plug in the boot when it is often heard that the spark is an abnormal phenomenon of the adapter,
Plug in the power after the boot. Not repair books.
If you replace the new adapter, please make sure that the adapter you are buying is compatible with your computer? If it matches, it may be a bad access to the power supply on the notebook, or your adapter's DC head and computer Do not match, too loose will be bad,
