Did a clean system install from machine B (while still in target disk mode). Hard drive checks out with no errors and is formatted in Extended Journaled.

DVD spins up but then three beeps.įired the machine up as a target disk and ran disk utility via remote control from another machine, we''ll call that one "machine B". Bought new ram, put it in, reseated it a bunch of times, still three beeps every time.Īttempting to restart using the system DVD by holding the C key, same problem. Computer starts with normal chimes, then when it gets to the grey screen with the Apple, I get the "three beeps". Now I can't get as far as the password screen any more. So I attempted to boot from my own Snow Leopard DVD, then I started getting three beep errors. I thought this was going to be an easy case of erase-and-install. My friend did not have the password to get into the machine and no original system disc.

They were given the computer by someone who didn't want it. I'm working on a Macbook pro 15 A1278 for a friend.
