Need help with my new psp

[Wig44.]

Well, I got my PSP today and I put in the battery, UMD and turbo stick duo and it doesnt turn on. So I put it in to charge and the orange LED that is supposed to show up to say it is charging hasnt. I'm leaving it on charge and hoping for the best but does anyone know would could be wrong/solutions or if I'm worrying over nothing?

Thanks!
Will

Has it turned on before? or is this the first attempt to turn it on?
