Must I erase the hard drive after installing a new logic board?
Tonight I made a second attempt to install a different logic board into a MacBook Core Duo that I've been working on. For background on this undertaking, see the details outlined in my question regarding MacBook Core Duo not working properly after internals were replaced.
I'm having the same issues as before, even with this second logic board, but I've noticed this time that the fan is working and the screen does indeed display that reassuring instantaneous white flash upon depressing the power button. So, I'm convinced the display is working properly.
However, even with all the internals operating correctly, when powered on, the sleep light immediately lights up and remains lit and when resetting the PMU, no tone is heard after the sleep light flickers, which is unusual.
What I'm wondering now, is if what I need to do is to completely erase the hard drive I'm booting with in order for the MacBook to boot up? Will this possibly solve the issue? I've tried booting from an install disc, but the optical drive won't read the disc and it ends up holding the disc hostage until I extract it by taking the drive apart. I'm thinking about attempting to boot from my MacBook Pro via target disk mode to avoid this issue, but I'm not sure how well that would work. Other than that, I've wondered if disconnecting and reconnecting the PRAM battery could help get me anywhere. I feel like I've tried everything and haven't gotten very far.
Thanks again for your help, reliable and wise iFixIt community.
After switching out the RAM cards I'd been using throughout the whole process with an older set from the original computer, I was able to get the MacBook to fully boot the OS from the hard drive with all the data intact and problem free. For some reason however, when powered on, the "system can't locate a startup volume" question mark folder flashes once before going to the Apple logo and booting up. I've heard from people and Apple Geniuses that this means that something is wrong, but I'm unsure of what. It doesn't seem to be causing any software issues. The only problem I am having now though is that the keyboard and trackpad on the top case are completely unresponsive, even thought the power button works. Any suggestions on how to fix this issue would be greatly appreciated. Thanks!
