Three beeps on MacBook startup
My roommate Molly just purchased a brand new $999 MacBook. I was of course there for the unboxing and original setup. We fired it up right away, and were greeted by the chime and then a series of three loud beeps right away.
Some quick research suggested it may be the battery so we plugged it in and made sure it was fully charged. Did not help.
A little more research suggested it might be memory related. Since it was FedEx’d, I thought I’d yank out the RAM and stick it back in there to make sure it was securely in place. That’s exactly what I did and it fired right up.
So– defintely check out that your RAM chips are securely in place if you have the three beeps problem.
