Oof! I opened up the back of my GLO to see if the SD card was 4GB. It wasn't, it was 2GB, fine, but when I snapped the back cover on again, the power slider was dead

I tried paperclip reset, I tried factory reset, nothing works. I obviously did some harm to the hardware, but I can't see anything in there that seems damaged.
My question: Has anybody had this happen, and if so, is it at all possible to fix?
