Your best bet would be contacting the computer's manufacturer and ship it out to them to repair it. This happened to me once when my dog ripped out the charger by running through it. They were kind enough to send out a box for me to ship it for free and took care of the repairs free of charge. It was back to me in 4 business days.
I had purchased the laptop within two years of the accident though, so it was still under warranty. Most computer companies will still assist you with this if your warranty is up though.
Best of luck.
