Replaced main battery, screwdiver slipped, 50% DEAD. Tips?

Hello all,

This is my first time on this board because well....I've never had a broken item. So here I am. I just received a new battery (ifixit replacement battery) for my MacBook Pro 15 unibody mid 2010. Once I got the new battery in, and was pushing the battery plug in (like a dumb A$$ I used a screwdriver) I slipped and ran the screwdriver lightly across the circuit board for about 10 cm (roughly the width of a credit card). I looked with a magnifying glass and can't see damage but there is a light scratch running across the board...very faint, but still there.

So I re-assembled, hit the test light, and all the LED's lit up indicating a full battery. I hit the power button and I heard the hard drive kick in with it's little "klink" sounds, a faint sound of fans, and nothing. The front right (white) power led doesn't come on, no screen, no keyboard lights, but the optical drive did take a DVD but won't give it back.

So, I powered down, took RAM out, and tried to re-start with battery and no RAM. SAME.

I placed old battery back inside, with and without RAM...SAME.

I put new battery back in, powered up with 10 second press of power button...SAME. Now the hard drive "klinks" on, and nothing else.

Can I reset PRAM, or clock battery, or anything else that will help me narrow this down? Could I have fried the board with a light running of a metal screwdriver (boy that sounded dumb coming out! :-) No welds or physical damage to board that I can see under magnification.

SUMMARY:....Battery is good, magsafe works, swapping batteries has no change in behavior and I tried with and without RAM....hard drive engages, fans go on, optical accepted DVD.

I humbly wait and hope I hear something. Thank you in advance to anyone that tries to help.
