PowerBook 17" says I have no mouse or keyboard!

Looks like you got ahead of youself here by powering on your device too early.

Diagnose the problem-

1. Where is the damage located exactly?

2. Is it repairable without replacing the logic board?

3. Go back to see what you did and make sure you didn't miss a connection.

4. Take a picture of the damage and post it for a better answer.

5. Good luck.

It is extremely risky to work on a motherboard when it is still powered cause it's easy to short a connector if the wrong pins enter in contact during the connection. Now try to clean the connector and the socket where you see the burn marks. Use a very small flat screwdriver and carefuly scratch the pins to remove the burn mark and clean the metal. If you're lucky and nothing else is damaged you may be able to restaure the keyboard connection.

Thanks for all the good advice. No use talking about beeing careful with power and connectors. I learned that now. I tried to scratch the pins with a small flat screwdriver but no luck. I hope to take a picture of the part. It is so small I need a good macro.

Here are some pictures. You can see where the damage is.

Your motherboard seems to be damaged. We clearly see the busted resistors and who knows if the top case may be damaged by the short too.

Doe this mean it is not repairable and i would have to buy a new motherboard?

you would have to find a skilled technician to check the busted resistors and replace them if needed or buy a used motherboard on ebay but first the top case should be tested cause it could also be the problem.
