Problems after hardrive upgrade - Ibook G4 "12

The connector you broke is the power connection. It has to be resoldered or you just thrashed your logic board.

Don't try to resolder the connector directly to the motherboard, you would probably scrap the board. Instead use two small wires and solder them to the two contacts on the board where the connector was seated then solder the other ends of the wires to the connector. That's micro soldering and it's not a newbie job so my advice would be to find a electronic technician to do the soldering. If you decide to do it yourself don't put solder on the motherboard but only a very small amount on the wire end then ajust the wire to the contact on the motherboard and briefly apply the soldering iron on the wire end.

Gook luck !!

I just replaced my HD and it won't power up at all. I didn't mess up the power connection that I'm aware of. I went back to that point and double checked that I had reconnected the blue/white power wires and that they were not loose. Can you think of anything else that might be preventing it from powering on?

Did you make sure you reconnected the DC in board to the motherboard?

I never disconnected it. I used a different guide that bypassed that step by sliding the casing around the DC. I know it works because it is orange, and the battery is recharging. btw, here is the guide that I used. It is all the same except for the DC removal.

boltzwagon, first I'd try to reset the power manager: unplug the ac adapter, take off the battery and push on the power button for 5 seconds then reinstall the battery, connect the ac adapter and try to boot the ibook.

You say the ibook doesn't boot but do you ear a hard drive activity and the reset sound of the optical drive when you push on the power button ? If no activity at all then you have an electrical problem caused by:

- a bad AC adapter combined with a dead or low battery

- a faulty power switch

- a bad DC board

- the DC board cable connector is not well inserted in his socket under the motherboard

- a dead motherboard

To check if the problem is related to the power switch: take off the ibook top case, disconnet the power switch connector from the motherboard, connect the ac adapter, carefully enter a very small flat screwdriver inside the power switch connector and briefly short the two pins inside the connector. The ibook should then boot and you now know that the problem is the power switch.

thanks. I will start troubleshooting with these tips and upadate my progress later. Again, I appreciate your help and expertise.

When I push the power button, there is no activity at all. I tried resetting the power manager first.

Nothing.

I am pretty sure the AC adapter, battery, and DC board/cable are all functioning properly. Here's my reasoning. The battery was at 0 charge. I plugged in the AC adapter and it charged up the battery fully. That would mean that the adapter works, the DC board works, the DC cable works and is connected properly, and the battery holds a charge. Let me know if I should have any reason to think that any of these could still be the problem.

I tried your suggestion of bypassing the power switch with no result. This would leave only one option--a dead motherboard. Which, of course, would suck. I see that this site has them available for purchase, but I am not guaranteed that replacing it would solve the problem. It's a 4.5 yr old computer, so I guess I'm gonna have to cut my loss at some point and upgrade. Let me know if you have any more thoughts. Thanks.
