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 power off 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?

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. MacBook Pro :: Does Not Turn On - Light Blinks And Beeps 8 To 9 Times May 21, 2012 3 successive tones, a 5-second pause, 3 successive tones. 1 tone, a 5-second pause, repeat = No RAM installed. I waited ten minutes and did some quick research on my ipod. I pressed the power button until it was quiet. Talk about a rude awakening! The screen was dark and did not respond to keys or mouse clicks. I keep my laptop running most of the time, and at 4 o'clock this morning it started beeping at me.A reflow (heating of the solder balls under the GPU at around 250 degrees) could fix the problem temporary but in order to have a permanent result you need to remove the GPU and replace the solder balls (reballing). 3 beeps indicate GPU (video chip) issue.Macbook Pro Beeps 3 Times And Does Not Boot.3 successive tones followed by a 5-second pause.

Either your computer's memory was removed or something is interfering with the system checkup. If you hear this pattern of beeping, it means that the Mac could not find any RAM installed. When you start your Mac, it will automatically run system diagnostics. This happened on my Macbook Air and I transferred my data to a Macbook Pro the. Some notes, I know this isn't a ram or hardware issue. I've searched for this issue already but haven't been able to find a solution. It beeps once, 3 seconds pass, then it beeps again-this repeats. My Macbook randomly beeps two times every couple of minutes or so.
