How to fix an overloaded psp 1000?

I know this is a bit old of a system, but I used a laptop charger with the same port after it was advertised to work to charge a psp, but now I cant turn it on, cant get a charge light when I plug it in (with the actual psp charger I bought after this), and get an orange light when I put the battery in just the right way. Is it even worth it to try and fix it at this point? It has a nice design so I want to save it if possible.
