Hello, everyone. When it comes to power supplies and the energy flow inside a computer, I can get a bit lost, so I have a question. I'm repairing a friend's Toshiba C655 laptop and inside it seems that the DC jack cable that goes to the motherboard is fried in half. It looks as if it got so hot that it separated from the black cover around the cable and then split in half. I suspect that the AC adapter that they were using was too powerful for this specific laptop, but with all of that in mind, I am wondering if something like that fried the whole motherboard or not. I'd hate to order another DC cable, replace it and find out that the motherboard is fried. What do you guys think about this situation? Thank you so very much.
