If anyone has anymore info in regards to this issue that'd be great. Sometimes it will beep and then boot fine, others it wont boot at all and just stays on a grey screen. As soon as it happens again i will.īecause it only happens every once in awhile, probably once every 5 times i boot the machine, its hard to catch, and even then its random. It has since happened twice more, and i have yet to remember to count how many Beeps the machine makes. I powered it down and turned it on again and it was fine. The computer then would not boot to the Apple Logo. However, the next time i booted the machine, I encountered the same problem that the OPer had.Ī number of loud beeps coming from where the HDD is situated in the machine. Now it came back with the new drive, I then installed 10.5 and did all the updates.

There were no issues, so i powered it down and dropped it off to a Mac certified tech to have the upgrade done. Now when it arrived to me, before i got the upgrade done, i only booted the system once to check that the machine worked. Now as soon as it arrived and went and upgraded the standard 200GB 5400RPM system drive with a Seagate 320GB 7200,3 Drive. It hadnt been used for much by the previous owner, sitting on a desk as a desktop computer mainly. I just bought a second hand MacBook Pro 4,1 (2.4ghz, 4GB Non ECC Ram) If your MacBook Air or MacBook Pro computer is broadcasting 3 successive beeps at intervals of approximately five seconds, it means that RAM memory did not pass the data integrity check. The beeping indicates that there is an issue with your notebook’s RAM.

Hi, bringing back and old thread in a hope to find some answers to the same problem. Why MacBook beeping 3 times and won’t startup Typically it’s a RAM issue.
