Réponse à : « MacBook Pro not booting up »hey whats up Dan thanks for checking in and trying to help out i actually figured it out took a while but i figured it out turns out it was a bad ON & OFF button i ordered a whole new upper case with a new keyboard no button and mouse pad from ebay for $20 bucks swapped all the components to the new upper case and it worked like a charm.
Réponse à : « Boot up after replacing hard drive »Sounds like you need to reinstall the operating system. I would turn it on and as soon as it turns on try this: 1. Hold down the Command Key & the “R” key @ the same time. Wait till recovery mode shows up and follow the instructions from there on to install the new OS. 2. Hold Down the Command + Options + R Keys at the same time this is for Internet Recovery mode. 4. Try resetting your PRAM by pressing and holding the Command + Option + P and R keys right as you turn the computer on and wait for the computer to restart on its own and chime once again then let go.
