Thanks for such a quick response!   I dropped the glass on the left side of the keyboard (about the s,d,f keys).

Also, when I attached the ac adaptor cord the green light comes on for about 2 seconds and then shuts off.

Thanks again!

First, are you under warranty? Second, do you have accidental damage service? (I assume not, if you've come here for advice.)

Warranty will not cover something like this, for obvious reasons. But I would say the best thing would be to get an estimate on it. It may save you time - it may or may not be worth repairing, if it's the motherboard. On the other hand, if it's not the motherboard, then you should be in good shape, just in need of a few part replacements here and there.
