Macbook pro 3 beeps when booting from usb manual#
I went through my instruction manual as well as online searches to see if maybe I could somehow restore the computer to factory settings.
I tried restarting it in safe mode (holding the shift button down during startup), but it only resulted in the computer freezing on the logo screen for about five minutes before shutting itself off (no beeping or light that time, though). It froze on the logo screen and continued to beep for a half an hour before I forced it to shut down (control+command+power button). It did the opening chime and then the logo screen came up, but then it started a series of beeps along with blinking battery light (it is fully charged). I waited for about an hour before manually starting the computer by pressing the power button. It shut down fine, but then didn't start up again on it's own. It stated that it needed to restart to complete the updates, so I confirmed it. I have a brand new Macbook Pro (Christmas 2011), and today it was installing updates.

MacBook Air, Mac OS X (10.7.3), Late 2010, 1.86 GHz Intel Core 2 MacBook Pro :: It Makes Random Beeps? Mar 19, 2012 I think it's strange that it did it once but hasn't again despite numerous restarts and also strange that it happened immediately upon hitting the 'option' key when the screen went dark, as I always do. I've done a bit of research and it sounds like it's indicative of a RAM issue but want to see if anyone knows for sure.

It's the first time that I've heard this beeping except when I installed a firmware update a few weeks back. I restarted and held down the 'option' key again, booted into Windows 7 fine, and have since rebooted into OS X as well without issue. The fans started running pretty quickly and I held down the power button and it finally shut down. 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 when booting from usb 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. MacBook Pro i7 8GB - iPhone 4, Mac OS X (10.6.7) MacBook Pro :: 3 Beeps On Start Up? Mar 22, 2012 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?

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.
My Macbook Pro battery had run down (it does quite a bit) so I rebooted with the power inserted.
