(19v, 3.74A) power adapter to charge the notebook, the first charge for 10 minutes, the second charge for 20 minutes, the results of a black screen can not boot the notebook , The power adapter is also broken, I then use a good power adapter to charge the notebook, the adapter lights flash, and some master said the notebook motherboard may be broken, I would like to ask what is the reason why the notebook can not afford machine, if Is the motherboard burned out, that in the end is the power adapter burned to the notebook motherboard to burn out, or laptop motherboard short circuit to the power adapter to burn out? Thank you, everyone gave me an answer, I took all my points out
General such a problem is the laptop motherboard circuit and the cathode 19v short circuit caused. The power adapter is not good quality will burn the notebook. In fact, this problem is still a good solution. Repaired between 180-260. Specifically have to see that short circuit. You put the battery out of power to try to see what reaction. If not enough, then the motherboard is short-circuit, and only to repair.
