MBP won't turn on after upgrade attempt

[Drakorex]

I was attempting to replace my late 2011 MBPs optical drive with another hard drive and it no longer turns on.

There are no light or sounds at all, no battery power indicator, no light on the MagSafe.

During the process everything was removed carefully and replaced, but a screwdriver slipped and scraped the very edge of the logic board although I don't think that should cause any issue?

Any ideas that could help me please?

It should require a lot more then it slipping I would think, unless the LB are wimpy. Never actually been in a macbook but I have been in several other laptops. I do assume you removed power while doing this upgrade right?

Redo the job, see if you missed anything. I've missed things once in a while even though I was so sure it was done perfectly.
