Hi At first the laptop was off because of Poured water.it8586e was damaged and changed .after change of it8586 laptop turned on and had screen. but after several seconds it shuts down. The ec_on signal falls down and then system shuts down. I removed pr414 and pulled up the pin 13 of rt8243a (ENM) to LDO3 , so laptop worked well without shutting down. but there is a new problem in this condition.the problem is laptop could not switch by battery .It only switchs by external power .after switch i can remove the power and it works well again. The question is why ec_on drops to zero.how can i solve it? help please . THe ec_on falls down--->system shuts down ---> ec_on rise up again and system can switch again. |

думаю ec_on нужен для выключения каналов шим в режиме работы от батареи. еще, он возможно, выключает ноутбук в каких-то аварийных режимах. для начала, я бы искал проблемы в заряднике, батарее и логике их работы. |
