Rubber Power button cover replacement

My N3060 NIA has a rubber membrane covering the power button. The membrane on my KOBO is so worn out that I have removed it. I can still turn the unit on using a tooth pic or match stick. Can I get a replacement rubber membrane/power button cover?

I have this problem too, but I can no longer turn it on using a tooth pick. Can someone please post an image of what the back of the motherboard is supposed to look like?

Thanks
