HP Pavilion DM4 Won't Power On

[dios_et_dios]

I have a 2 year old HP Pavilion dm4-1060us laptop. I opened it up to clean the fans and apply some new thermal paste. I have experience building computers and fixing laptops, so I was very careful.

When I went to turn the computer on again, it seemed like everything was booting okay (It got at least to the Windows screen), so I walked away. When I came back it had turned off. Now, when I hit the power button, the light for the ac adapter goes off and nothing happens.

Any suggestions? I tried removing the AC adapter and battery, holding the power button for 1 minute, and then trying it with just the adapter. Nothing.

Also, the computer was low on battery before I dissembled it the first time. Any chance that the problem is with charging the battery. I know that the AC adapter is fine.
