PSP wont turn on!

[Blue Cypher]

Hi, i left my psp in a locked room in work over the weekend and the ac adapter was plugged in.When i come to use it this morning though my psp wont turn on at all, and the green light that usually shows its charging isnt lighting up or anything. I was wondering if anyone else had this problem, if the cable is broke that would explain why it wont charge, but i thought it still had a little charge left when i left it so if anyone could help me out i would be great full.
