Having issues after replacing battery

Hi,

I was replacing my battery and as i was trying to get the bios battery out, I used a metal object (I'm an idiot) and accidently hit something on the logic board causing a spark. Now, my computer won't start. The sleep light came on and then clicks off, then repeats. Nothing else happened. I tried taking the battery out, pressing the start button a couple of times for 5 seconds. The sleep light stays on and the fan, but it still won't start. What can i do????

Please help!!!!!! Thanks
