The sun roof leaked water onto the computer, does this mean the computer is ruin

What is your question?

Took it to a Volvo dealership, said it would cost more to repair the car as to what it was worth, they said we needed to get a new computer for the car, but could it be dried out, and the computer reset? As of now the car cannot be started.

How long has your 2009 Volvo S80 had this problem?

A few weeks
