Netbook won't restart?

Love my little laptop...was using it on battery power when it was getting low so I was going to plug it in while using my external cd/w/r.......but today for whatever reason I oppsed.......while connecting my external cd-w/r I accidently plugged my power cord into the cd-w/r instead of my netbook while the external cd-w/r was already connected to my usb port on my netbook....needless to say my netbook screen went on & off, on then totally off.....can not get it going now at all, even waited 20 minutes for battery to cool down......did I fry my netbook or is it salvagable??
