Beeping Noise!!!???

A couple weeks ago I was getting this strange 56 K modem type sound from the audio card. It was a happening at random times. It came from the speaker. I could hit mute and I couldn't hear it, if my headphones were in it would play through there. So it's coming from the audio card not some internal device. NOW, however, I am just getting beeps. It happens at random times still it is actually four sets of double beeps, like '" beepbeep--beepbeep--beepbeep--beepbeep"

NO, idea what this is. It's not something happening at log in or anything. I've rebooted etc. Any help? I have a Mid 2010 MBP with Snow Leopard.

Does this happen at start up? If so, read this: Power On Self-Test Definition-Part 2

You might run a Apple Hardware Test using your original install disk 2 and see if that tells you anything.

Probably the Apple store Genius bar is a good place to have this diagnosed.

What you describe is out of the norm.

Ciao.

Seems like there may be a problem with your macbook, it has happened to mine recently too but received three beeps instead of four. There is a list of how many beeps you get can be entitled to what is wrong with the laptop such as:

1 beep = no RAM installed

2 beeps = incompatible RAM types

3 beeps = no good banks

4 beeps = no good boot images in the boot ROM (and/or bad sys config block)

5 beeps = processor is not usable

ughh, really, this is the same old stuff everybody else keeps posting, THIS IS NOT A STARTUP issue. Sorry, just had to make this clear. EVERYTHING works just fine. I've never heard it at startup. I couldn't get the self test to run at startup using the "d" key. it just froze there and wouldn't load it. So, I will see if I can some tests with the install disk. Just have to figure out how to do that.

That is because in order to run the Apple Hardware Test (AHT), you need to insert disc 2 first: http://support.apple.com/kb/HT1509
