My Mac started beeping at me the other day and I am hoping that somebody can tell me why as it was definitely abnormal beeping.
I have a macbook pro 15 inch aluminum unibody that was the latest model when I bought it back in January this year. It came with 4GB of ram and a 300GB HD. I have not added any ram or changed the hard drive or added any third party hardware to the computer. I am running Mac OS 10.5.7 which I updated about a week ago without a problem.
The computer had been going with with nothing unusual and I was browsing the internet in Safari when suddenly I heard this disturbing beeping coming from my mac. The sound was quite short and quite loud. It reminded me of the beeps made by macs when you reset the pram. The beeps were quite random. sometimes occuring close together like a countdown and at other times being spaced unevenly apart by a few minutes. The beeps seemed to become less frequent when I disconnected from airport and more frequent when I reconnected. Eventually I changed user and then left my computer for a time and then changed back to the affected user and the beeps had stopped.
The beeps were definitely not my system alert sound as it sounded quite different. Also they didn't respond to changing the system volume, whereas my alert sound did. I ran disk first aid and it came up with nothing.
The only unusual thing is that later that day I was watching a movie on my computer while unconnected to the power supply and my computer ran out of battery life. Instead of going to sleep it shutdown. I restarted it after connecting it to the power supply and there was no problem.
Does anybody have any clues as to what might be going on?
