Replaced left fan for MBP A1151, and now have no sound.
I recently replaced the left fan on my MBP A1151 using the replacement guide. All went well, but when I booted back up, there was no sound output. The initial little chime that sounds when the computer first turns on is there, but I have no audio output from within the OS. I opened it back up and rechecked all connections, and everything looked good. I was having no audio issues before the repair.
The fan is working fine.
Is this a good question?
