After removing the logic board my number keys don't work?

I was having problems with my heat sink, so I followed the guide to replace it in my macbook pro which requires removing the entire logic board. I did this and then put everything back together, but now the number keys one through nine on my keyboard don't work.

I've tried reconnecting the keyboard ribbon, but nothing works. I also checked the "keyboard viewer" in system preferences and the keys will not work.

While I was removing the ribbon the first time, I'm worried that I damaged the connecter piece on the logic board. Did I totally mess everything up?

Can you provide a few hires pictures of the ribbon cable end and the connector so we can see the damage.

It's possible. Many people "read" the guide not study it so they pull off connectors because they didn't unlock cams or pulled in the wrong direction. Photos would help us determine if there's damage.

If there is damage soldering logic boards is generally not a good project for those who tore parts off the board in the first place… soldering computer components requires special tools, & lots and lots of practice. A electronic or computer repair shop may be able to fix or replace a component on the board for you.

While I do understand your frustration here Apple is not alone in soldering connectors onto the logic board. Sorry to hear you have a damaged connector. Even I've broken a few with little effort.

I would first see if you can locate someone with the skills (SMT) to put a new on onto the logic board. That could save you the need to replace the logic board.

As to your other question the BIOS (EFI) is on the logic board on a EEPROM chip so you don't need to worry the new board will have it on it. And after you get things back together it will automatically update as needed via the OS.

Yeah so I've done a lot of investigating into this: I definitely did pull off the connector from the logic board, and because mac solders everything in, that means replacing the entire logic board. I've actually managed to find a used logic board for about $350.

Here's new a question: do you guys think I should do it or should I just buy a new mac?

Also, if i replace the logic board, how do I reset the BIOS or whatever it is in the MacBook Pro to make sure that the board works correctly with all of the other hardware?

Thanks!
