Laptop Not Booting Properly

[xCloudZerox]

In a nutshell: I disassembled my entire laptop in order to replace the thermal compound. Now when I try to start it up, only the keyboard LED's and touch control panel LED's light up and flash at regular 1~2 second intervals. The screen is completely blank.

 

Any ideas what could have gone wrong?

Yeah, you may want to open it up again and make sure everything is connecting properly.

It was my first time opening up a machine to such an extent, so their may be a possibility I didn't connect something correctly. I want to say I'm 99% sure I did connect everything, but I guess i'll go ahead and reopen it within the next week or so.
