How well does Gamestop check handheld systems when they're traded in?

I plan to get a used PSP and I was wondering, do they repair systems, or even check to see if they are fully functional? Also, must I sell the adapter too?
I'm selling my old PSP to get a new one. My PSP 1000 is old. However, I do not buy used systems.
