So I’ve read everything i can about fixing my laptop and nothing worked. I don’t know what is wrong with it now. The previous issue was a severed charging cable(female end). And i replaced that. Battery charges. And hold a charge. Power light comes on. And i hear a low buzzing/humming sound which sounds like the CPU. Which i was hoping is a good sign. I need all the help i can get if it could be done in house. Please and thank you.
