Does anyone know what the problem might be and if so is it fixable. Thanks 
It could be one of a lot of things, hard to say without more input from you. And anything is fixable. Just depends how much you want to spend to fix some things.
Was it dropped ? ?
That's probably the most important question. My next question would be are the lights on the adapter or the laptop? And does the charging/charged light indicate anything? I know that my cats knocked my laptop off my couch and the power button got damaged. Luckily everything is alright, except the small piece of plastic from the external button to the internal switch. So sometimes I have to press it multiple times at different angles to get it to start. so yeah... could be anything.
