Is there any way to fix the PSP's power button?

Really, don't ask me how this happened...
But I was wondering if there was any way to like buy a part, and then fix it?

Here's a picture of my PSP

Those pictures dont do any justice. Cant see exactly what happened to the button.

Did it fall off?
Did it break?
Did it fall inside?

Anyways, if the whole power switch is still in tact, just open up your psp and re-insert the button.
You can find a guide on llama.com if you need one.

The buttons itself is gone, but I could still turn it on.

Someone else already offered me help, but thank you too [:
I'll buy a new one.

The first site I think of is Game Asylum
