After LCD replacement MacBook doesn't power up. Any suggestions?

Yesterday I replaced the damaged LCD on my 2008 MBP 15", model A1260. It only took a couple of hours and did not seem complicated using the iFixit guide. Once I got it back together, with no excess parts left over, I connected the power adapter and it worked as usual, indicating that the battery was charging. It now shows that the charge is complete (green light). However, when I pressed the power button to fire it up, nothing happened. It is not powering up at all, no sounds, no HDD spin-up. Apparently the power button is not activating the power up sequence.

I am pretty sure that all the connectors were remated and were making solid contact, but of course I could be wrong. It looked to me like the ribbon cable connecting the keyboard and trackpad to the motherboard could potentially become disconnected when the upper case was reinstalled (step 9 of the repair guide), but I tried to be careful in doing it.

Any thoughts? Thanks.

Recheck the ribbon cable connection. Don't screw it down until it's booting. See this Question you may have made the same error.

If this answer is acceptable please remember to return and mark it.

I finally had a chance to tear into the MBP. Sure enough, the ribbon cable connecting the keyboard to the motherboard was not connected. I reconnected it ... it simply pushes onto the connector. Before I secured the keyboard I plugged in the power adapter and fired it up and it worked like a charm. The new display looks great too!

Thanks.
