Sony Vaio - Not powering up, perhaps mobo?

[Luisa_1]

I have a Sony Vaio VPCSA and it doesn't want to power up at all. It was working fine and then we heard a bit of "poof" and then it was dead. Reckon the motherboard would be dead?

Hi, you heard a "poof" and the laptop is dead. What do you want me to do?

Well, I presumed that posting a question to a forum would provide a probable answer. The question was related to whether it might the motherboard or the DC Jack. So if you don't have a suggestion, then a response is not expected.
