Good morning donbart,
Sounds like you probably did in the motherboard. They have a number of surface mounted fuses that are not easily replaced without specialized tools and training.

However, before we jump to that conclusion, there are two things that we can try. (Remove the battery and don't replace it until you are done with these processes) Reseat everything, or take it down to "bare bones" and see what happens.

Reseating everything means to tear it down to the point that you can access every connector and removable component. Disconnect each cable, and component, one at a time and plug it back in. While you're doing this, check for water stains (mineral deposits) and gently clean them with alcohol if any are found. If it doesn't come up after doing this, try the bare bones approach.

By bare bones, I mean to disassemble to the point that you only have the a/c adapter, motherboard, 1 stick of memory and the display hooked up. At this point, if it doesn't come up farther than it does at present, you more than likely have a bad motherboard.

If it does show signs of life, start reconnecting one item at a time, and try to power up after replacing each item or connector. If you replace/reconnect something and it no longer does anything, you have just located the part that is bringing your system down.

Using this approach, I have seen memory cards, hard disk drives, keyboards, mice, touchpads, floppies, cd readers all cause this type of problem.
