When plugged into the computer, the AC adapter blinks. Is that a problem with DC harness or recently replaced DC connector. If the motherboard fails, I replace the whole unit. I was really hoping there was some sort of fuse on the motherboard or maybe that dc jack…. I think you have a good chance to fix the laptop if you replace the power button board which located under the keyboard cover. This sounds like motherboard failure to me.
