I broke the power button

Question

I broke the power putton on my Rio 6GB Carbon Pearl. I have dropped it a few times so it broke off. When I shake it I can hear it rattle around. I know I didn't damage the hard drive though because I can still charge it and it turns on that way. I have been using a pencil or a pointy object to poke inside and push on the thing the power button was pushing down on to make it turn on. This worked for a little while, but now it has completely stopped turning on (unless I charge it) Can you please help me? Thanks!
