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)
