Wire responsible for power is broken

I have a sony fw and like many others the hinge was loose.
It eventually fell off leaving the wire exposed.
After a while the wire broke.
There is no way to charge my computer? How can i fix this? Glue the wire? see if the warranty is still valid? if it is how much will it cost? how much will it cost if it is not? Find someway to charge the battery(like if 3rd parties make battery charging stations) and use the computer that way? What are my options and their associated prices?

I'd appreciate any responses.
It is very difficult to get by without a computer.
You never realize how much you depend on it till its broken.

Thank you.
