I am about to fix a laptop for a customer and I am not quite sure what is wrong with it. I kind of have an idea, but not completely sure. They said that it has been dropped and won't turn back on. I plugged the battery in with charger, nothing. So I am thinking that it is the mobo. Tell me what you all think. I know the hardrive is good because i pulled it out and tested it. So im pretty sure it's the mobo or processor or a combination of both. Let me know!
