It beeped 3 times, stopped, beeped 3 times, stopped etc. What was unusual, however, was that it immediately started beeping loudly when I held down the option button and continued to do so without ceasing. This morning, when I got into work I restarted my Late-2010 MacBook Air (128 GB HD, 1.86 GHZ Core-2 Duo, OS X 10.7.3) while holding down the 'option' button as I normally do to access bootcamp and load Windows 7 because I need to use Excel Macros during the work day.

MacBook Pro, Mac OS X (10.6.3) MacBook Air :: 3 Beeps Continuously On Restart? Mar 9, 2012
MACBOOK PRO 3 BEEPS FIX INSTALL
System install was a success and was able to restart machine B successfully from the hard drive of the faulty machine. 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. Fired 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.Attempting 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.

I then booted up this morning with a full battery and the boot up took a lot longer than normal - maybe around 3 minutes on the spinning logo, and then finally booted - are these all worrying signs?
MACBOOK PRO 3 BEEPS FIX UPGRADE
This i7 is coming up to its first year (which I think is covered by Apple?) and I *think* this maybe a memory issue? If it is, and my Mac is covered, then by a sheer stroke of luck, I decided to get Apple to fit the 8GB memory at the time of purchase (bad I know! and I don't usually do that) BUT that would mean that Apple fitted the memory upgrade and I haven't touched anything myself. However this time, I had the frozen screen saver, and a continuous 3 beeps which I've never had before in a loop? I then re-pressed the power switch on the Macbook and it rebooted fine and seems ok. I get a frozen screen saver which is normal, while the progress bar finds it feet back on power. I tried also turn on laptop on SMC bypass and all missing rails have a right voltage only PPVCORE_S0_AXG2_L & PPVCORE_S0_AXG1_L are not present.Īny ideas ? Is any chance that something else could cause this issue.My Macbook Pro battery had run down (it does quite a bit) so I rebooted with the power inserted. I have thinking maybe CPU is not connected properly but I bit worried with next soldering attempt it will die as to many times heated up. There was no liquid damage on board with 3 beeps. Got it with 3 beeps issue have tired reflow ram replace PCH no luck I decide to replace CPU because it was getting crazy warm.Īfter replacement (I remove same CPU from Donner board) with was liquid damage but I was getting a display but it was too badly corroded to fix and many things doesn't work properly.Īfter CPU swap laptop is turning on with no beeps but there is no display no chime fan is spinning I measure board and no power on a main rails. I have this MacBook Pro for repair board 820-3332-A
