Well i decided to try this because i fixed an imac G5 isight this way, it had screen and logic board issues, random shutdowns, etc... you could just press on the logic board in a certain spot, and it would just shut off..

I fixed the logic board by reflowing it, but i still havent gotten around to replacing the screen to rid of those annoying lines. However, after reflowing the lombard's CPU card, all problems did go away. However I am going to have to get the PROPER AC adapter for it. as i cant charge the battery and run the machine at the same time. it wont charge and the AC adapter gets bloody hot.

Soon as i shut the lombard down, it charges right up.
