Has your motherboard got a part number on it?

According to the P/N in the thread title, you have a Sony Vaio Duo 11.

Ebay has a bunch of boards for that model, but they're really expensive:

In my opinion, it isn't worth fixing it. You're going to buy a used part which has the exact same potential defect that caused your current device to fail. It also has no warranty if it does fail again.
