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.

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

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.

So easy that I actually wouldn't take it into Apple. The good news is that is one of the cheapest components to fix (assuming it actually is the memory at fault and not something else).

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.
